Hello!

You are now the proud owner of TerraTecs EWS AudioSystem for music and audio-production and we congratulate you on this decision. You have chosen a state-of-the-art audioproduct and we are confident that the AudioSystem will serve you to your expectations and will provide you with lots of fun in the years to come.
This manual will cover both EWS 88 MT and EWS 88 D. The installation and use of the two is generally identical and, as such, we will only go into some specific details wherever necessary. Following is a summary of what you now have in front of you.

AudioSystem EWS88 MT

High-quality audio performance. The AudioSystem EWS88 MT gives you analogue recording and playback of audio to a very high standard. The break-out box 88AX is equipped with the latest 24-bit converters with up to 96 kHz sample playback rate. This results in a remarkable s/n ratio of 108dB(A) using the analogue outputs!

AudioSystem EWS88 D

Flexible ADAT connectors. The AudioSystem EWS88 D gives you digital recording and playback with its ADAT-LightpipeInterface. This offers up to 8 audio channels with 24-bit resolution. The optical interface can also transmit S/PDIF-standard signals and Raw-Data, like Dolby AC-3. Last but not least, ADAT signals can be converted to S/PDIF signals and vice versa.
Recording and playback of audio in the digital domain. The AudioSystem EWS88 is equipped with one stereo 24-bit S/PDIF-format connector for transferring recordings from DAT or Minidisk to your PC entirely in the digital domain. In addition, you have full access to all common sampling frequencies and their settings like copyprotection and generation-bit. The optical S/PDIF-Interface on the EWS88 D gives the same features (i.e. AC3 and DTS).
Software la carte. The ControlPanel the brain of your EWS88 will become indispensable before you know it. It features a well laid-out user interface, and intuitive control of the cards settings make the day-to-day use as easy as possible. You will also find Emagics MicroLogic AV (EWS-Edition) as part of the software package to get you started. The current version 4.1 of the MIDI/AudioSoftware offers you real 24-bit hard disk recording.
The drivers quality leaves no-one second-guessing. Special ASIO 2.0- and GSIF support allows for incredibly low latency. We hope you will enjoy using the EWS 88 and suggest, to flip through the manual every now and then. Apart from the necessary technical information, we have prepared diagrams and examples in the relevant sections of this manual. We believe that even experienced users will be able to learn something. At least you should read the small summaries, which are framed and highlighted with an exclamation mark. The frames summarize the following paragraph and contain important tips concerning the setup, which will make your everyday work with the EWS so much easier.

Playback of multimedia players or windows system sounds through MIDI-Mapper is preferable.
Should you select EWS88 MT (D) MIDI, then all MIDI data, which is using MIDI-Mapper, will be transmitted through the MIDI OUT on 88AX, or the MIDI interface on EWS88 D. This allows you to use external sound modules for playback. Important: All settings mentioned above do not compromise MIDI playback in the most common sequencers.
Card connectors and their applications.
There are numerous high-quality connecting options with the EWS88. Here we would like to explore these options and describe the corresponding setting in the EWS88-ControlPanels in detail. In addition, you will find tips for regularly used functions. Tip: In order to understand the internal routing, you should read the chapter ControlPanel. from page 53.
Analogue outputs on EWS88 MT.
The analogue outputs on 88AX accommodate musician friendly levels of 10dBV or +4dBu. You can plug in your mixer and/or your instruments.
General. The AudioSystem EWS88 MT is equipped with 8 high-quality outputs (labeled OUT on the break-out box), which can be accessed individually. The connectors are of the Cinch(RCA) type and are always displayed as pairs in the ControlPanel (1/2, 3/4, 5/6, 7/8). Naturally, you can also access the channels individually. All output levels can be set between 10dBV and +4dBu in the ControlPanels Settings.
Safety-warning: Never plug analogue instruments into the jacks if the power is on! This will protect you from electric shocks, as well as your speakers and your hearing from sudden signal peaks. When plugging in digital instruments, you should at least turn down the volume.
Analogue inputs on EWS88 MT.
The line input-sensitivity on the 88AX may be controlled individually. You can switch between 10 dBV and +4 dBu and adjust the gain controls in order to make the most of the 24-bit converters.
General. The AudioSystem EWS88 MT is equipped with 8 high-quality inputs (labeled IN on the breakout box), which can be accessed individually. The connectors are of the Cinch(RCA)-type and are always displayed as pairs in the ControlPanel (1/2, 3/4, 5/6, 7/8). Naturally, you can also access the channels individually. The input sensitivity may be switched in the ControlPanel between 10dBV and +4dBu in Routing / Analog Input Levels. 10 dBV is very common in home-studios (the signal-levels are comparatively low, which is compensated for with the higher input sensitivity). +4 dBu is generally a professional setting (Instruments are powerful enough, hence the input sensitivity is acceptable). If you find that one of your instruments does not deliver a high enough level, you can increase the sensitivity in 0.5dB increments in the ControlPanel.
You can find more information on controlling inputs in the chapter Software. from page 47.
Interesting notes. Connecting and recording from turntable. Very hip is currently the restoring and archiving of Vinyl or Schellack recordings. The AudioSystem EWS88 MT certainly does enable you to make high-quality recordings. However, there are certain considerations and we would like to point them out to you. A direct connection to the EWS88 MT is not possible, because turntables technically limited due to its pick-up mechanism provide a rather weak and extremely unbalanced signal. As a result, it is vital to slot in an amplifier (hi-fi-amplifier or a dedicated phonostage with optimized distortion correction). A Hi-fi amplifier is usually equipped with a TAPE OUT socket, which you can connect to the EWS88 MT. TerraTec does offer such a pre-amplifier for vinyl enthusiasts. The TerraTec phono PreAmp is equipped with a high-quality RIAA-EQ, as well as gain switches for the different cartridge formats. It also offers a mini-jack connector for use with standard sound cards. The power is supplied through the cards GAME Port. As such, it is vital to use a sound card which can operate in conjunction with the EWS88. We recommend our own TerraTec DMX Xfire 1024. Both components are probably cheaper than any comparable hi-fi amplifier equipped with a phono-stage. Software for digital transfer and editing is included in the EWS88 package. Samplitude Project from SEKD, for example, is optimized for handling large files and should pose no problem to beginners. However, conventional software alone is not really suited for dealing with the requirements of restoring audio files. In addition to the usual functions like editing, equalizing and volume, there are functions like removing background noise and clicks optimizing S/N ratios as well as other sound processing tools. And finally, a CD burning facility would be on everyones wish list. All these functions are offered by specialized software, which can be purchased from the following manufacturers: Algorithmix Dartech Diamond Cut Productions Sonic Foundry Steinberg Microphone. The analogue inputs of the EWS88 MT do not accommodate microphones, especially not phantom powered ones (48V). The are usually equipped with a 6,3mm jack or XLR jack so you might as well save yourself the time and not use your home-made adapters. If you are planning to record microphones with professional quality (i.e. speech, vocals or acoustic instruments), then there is no way around using additional peripherals. Dedicated channelstrips or mixing desks with suitable XLR-sockets AUX-Sends (or subgroups) can be purchased in the right shops.

The ADAT connectors on EWS88 D.
The optical connectors on the EWS88 D accept other instruments, which respond to sending and receiving ADAT and S/PDIF signals. Included here are ADAT recorders, digital mixing desks or DAT and MiniDisk recorders. An optical connection allows for up to 8 channels to be transmitted with a sampling rate of 48kHz.
General. Connecting ADAT compatible equipment to the EWS88 D is incredibly simple. Generally you will find a single input and a single output connector (IN and OUT). You can recognize the OUT connector by the red light shining inside it. Connect the ADAT out of the EWS88 D to a ADAT IN of your peripheral, and vice versa. Using the ADAT connection for recording, you need to ensure that the sampling frequencies of both are identical. To guarantee perfect synchronization you must switch the masterclock setting in the ControlPanel to External.
Skipping this important step may result in audible dropouts in the recording. Of course the external instrument must be switched to the appropriate setting as well. If you intend to connect both instruments in both directions permanently, you must decide on a common synchronization frequency. Which format is most suitable for your studio, can only be decided by yourself. You need to consider, that for safety reasons when synchronized externally, the EWS88 only transmits audio data which are identical to the receiving machine. But here also special cases are to be taken into consideration: Digital mixing desks (i.e. Yamaha 02R), do not transmit any audio data when there is no external synchronization present (i.e. when your PC is switched off). The suitable drivers for digital ADAT recording are EWS88 WaveRec. As up to 8 audio channels can be received, the drivers are grouped in pairs (1/2, 3/4, 5/6, 7/8). You can find more information on the drivers from page 48.
Useful information. The digital interfaces on the EWS88 all transmit bit resolutions between 8 and 24 bit, as well as all sample rates between 8kHz and 96kHz. The same applies to the optical interface. However, as an ADAT Signal is transmitted via a TOS link-cable, its maximum sampling frequency is physically restricted to 48kHz, because 8 channels apear simultaneously. The EWS88 D allows you to use optical interfaces independent from the ADAT standard and, for example, to the S/PDIF-standard. This will enable the card to transmit data with a 96kHz sampling rate. The relevant settings in the ControlPanel for this are described in detail from page 53. Various manufacturers of software DVD-players ( i.e. Power DVD, Version 5.55 ) support playback of DVD audio material through the EWS88. This allows you to split the signals ( 5.1 or 7.1) and playback AC3 or DTS material. You can find more information on the Power DVD on: http://www.cyberlink.com.tw. The AudioSystem EWS88 D allows you to convert ADAT-signals to S/PDIF and vice versa. The relevant settings in the ControlPanel for this are described in detail from page 53.

For example: You are using a Audio-/MIDI-Sequencer (Cakewalk, Emagic, Steinberg whatever). In your arrangement are Audio- and MIDI-tracks present. All audio tracks are routed through various effects (plug-ins) and are being sent to the card's digital mixer (i.e. 1/2). The MIDI tracks control two external synthesizers, which you can connect to input 3/4 and 5/6 of the EWS88 MT. In addition, you are also running a software-synthesizer (Generator, Reality, etc). This audio-program uses WavePlay 7/8. And of course, you also own a EWS64, which also receives MIDI Data. You can connect the EWS64 to the EWS88 using its S/PDIF-output. All 10 audio signals are routed into the digital mixer. You can manually set all ten gain-levels and pan positions and the master volume can be adjusted using the Master Volume-fader. (The Digital Mixer has a 36-bit resolution and can mix up to 4096 24-bit audio-channels. Wow!). On the Routing-page (refer page 56) you can set the output of the digital mixer to either 1/2 or S/PDIF, the master-signal can be transmitted digitally or analogue. Thats all, ControlPanel understood! Summary: If you want to use the EWS88 MT purely as a I/O-card for your Audio-/MIDI-sequencer, you won't actually need the digital mixer. As mentioned earlier, your sequencer (software) controls the volume levels and pan positions. They are routed to the outputs directly.
Settings. The settings window allows you to adjust a number of hardware settings, drivers and in response to our customer demands the color scheme. Routing. Signal routing is the most interesting feature in the settings window. Here you determine which signal is routed to the output and whether it is muted, or not. (All signals are routed through the digital mixer , but need not necessarily be routed through the master output.)
Usually, you will send an audio-signal (or multiple signals) from a certain audio program. This will be done by the windows drivers described as WavePlay-1/2, 3/4, 5/6, 7/8 and S/PDIF. Here you can determine, that a signal, which is routed through 3/4 is also audible through 3/4. Alternatively, it is possible to rout an incoming signal (a signal not from a WavePlay-driver) directly to an output. This is especially useful when you record a signal from your sequencer and want to monitor it directly.In this mode, the WavePlay-becomes inaudible. To summarize this section for the musician experienced with mixing desks and recorders: The signal routings described in this section are akin to switching between tape and line input on a mixing desk. Choosing WavePlay --> Out x/y means, youll hear the signal off tape (in the case off the sequencer). Choosing In --> output x/y youll hear the incoming signal. As a sound card-user, you will certainly ask yourself: What about the volume control?!. With Windows you are used to adjusting the volume-levels within the Windows mixer. This is completely sufficient when you are mixing different signals, i.e. (Wavetable-)Synth, CD input, line and microphone input, etc. This, however, is a real recording-system, which is to process signals from different programs and route them without signal-degradation to the output section. Basically: The volume levels should be set in the respective programs themselves. Imagine your sequencer is directly connected to the outputs of your EWS88 if you have ever used an external mixing desk, you would appreciate not having to adjust the volume-levels at three different points (in the audio-software, on the sound card mixer and the external mixing desk).

The I/O Board. An extremely simple feature of the ControlPanel. In case the 88AX becomes detached from the card, (this might be possible with tightened screws though), the converters must be newly calibrated. This will take almost exactly 250ms shouldnt hurt. However, you should make sure, that the module never becomes de or attached during operation. It could be damaged.

Output.

Here you can adjust the levels (between +4 dBu and -10dBV) for all outputs of the EWS88 MT. 10 dBV is very common in home-studios (the signal-levels are comparatively low, which is compensated for with the higher input-sensitivity). +4 dBu is generally a professional setting (Instruments are powerful enough and make noise less prominent, hence the input-sensitivity is acceptable).

S/PDIF Out.

Here you determine, whether the signal you are sending via the digital interface contains security information. It is possible to include a copyright protection signal into your (original) recording. This is especially useful when you send out some demo tapes and do not want (digital) copies made of your composition. Also included is the newly developed Non-Audio mode. Apart from S/PDIF and ADAT signals, AC3 and DTS signals (i.e. from a software DVD-player) can be transmitted directly to an external Dolby Digital Receiver.
Digital Out (only EWS88 D)
Especially the optical digital output allows you to choose the settings for the required format, even independently from the optical digital input. The optical output can send i.e. S/PDIF signals, while the optical input receives ADAT signals. For testing purposes, you have the ADAT thru-option , which will route the incoming signal directly to the optical output, bypassing the digital mixer and the drivers. Digital In (only EWS88 D)
The optical input can also be switched between ADAT and S/PDIF signals.
When switching between input sources, you are presented with two options: 1. ADAT IN S/PDIF co-axial The optical TOS-link input can receive ADAT signals, while the co-axial S/PDIF input is also available.

ADAT On Coaxial - S/PDIF

Optical Digital In

EWS Engine

ADAT In

Clock Source Clock In

S/PDIF In Coaxial Digital In
Both signals can be auditioned and processed simultaneously (ADAT- and co-axial S/PDIF) , but only one can receive the clock signal. Clock Source allows you to chose, which input is to be used for this purpose. Example: The co-axial input is connected to a DAT-recorder and the optical input is connected to a mixing desk with ADAT interface. The ClockSource is provided by ADAT. The mixer is the master and set to 44.1kHz. As the DAT-recorder plays with a sampling-rate of 48kHz the signal will be distorted. Even when the DAT-recorder is set to 44.1kHz, the signal is still not synchronized with the clock provided by the mixing desk, and the signal is still distorted (even though this is hardly audible). 2. ADAT Off S/PDIF Optical As the TOS-Link interface can transmit S/PDIF signals and the EWS88 D can only process one S/PDIF input, the co-axial input will not be available here and the Clock-source is set to S/PDIF input.

ADAT Off Optical - S/PDIF
If the MasterClock was set to internal synchronization, or if the card is the Slave in a Master/Slave-mode, the ClockSource setting will have no impact at all.
DMA Buffer Transfer Latency. Here you can determine how quickly an application (i.e. software-synthesizer) can access the Widows drivers (except for the SystemSound-Out drivers). The faster, the better one would be inclined to think, if there wasnt a catch. The setting is systemdependent and can cause audible drop-outs during recording and playback, if your processor cannot cope with the load imposed by the setting. If you notice these drop-outs during playback, you will need to increase the DMA Buffer Transfer Latency. Equally important is the tuning of the offending application. Many programs offer manual setting of the audio-buffers (here: WaveLab).
Striking the balance: For higher levels of speed, try to keep the number and size of buffers as low as possible. Lower the DMA Buffer Transfer Latency in the ControlPanel step by step. The drivers themselves are very clean and fast. This means that you should achieve respectable results in respectable systems.
Note: Setting the DMA Buffer Transfer Latency will not affect the performance of the ASIO or GSIF drivers.
ASIO Buffer Size. The ASIO Buffer Size is responsible for the speed of the ASIO-drivers. The smaller the number of samples per buffer, the shorter the time it takes for your software to send signals. This setting is also like the DMA Buffer Transfer Latency system dependent. In the best case scenario, latency will be only 3ms. On common systems with a common processor load , you will work with a latency of about 7-30ms. Please note, that you will need to restart ASIO-applications once you have changed the ASIO-settings.
Wave Playback/Record Mode. The Wave Playback/Record Mode determines, if you want to work with a single software application (i.e. your sequencer) or several simultaneously. As we have already shown (The Master Clock section), running programs with different sampling-rates is not possible. Identical recording and/or playback frequencies will not present a problem (simply switch to Multi-Application mode). The Multi-Track mode reserves all WavePlay drivers (respective WaveRecord-) for only one open application. This will usually be your favorite hard disk recording application. And it is in this case that this mode finds its application: In multi-trackmode, all drivers (WavePlay 1/2, 3/4, 5/6 etc.) need to be available simultaneously, and start in perfect synchronization. An extremely important feature, which is indispensable in professional sound recording.

Color- settings. One of the most important decisions in the ControlPanel will be taken here. You just cant help noticing colors, wherever you look. Even the dullest desktop can be revitalized with a set of fresh new colors. Enjoy! ;-)
PS: No seriously, reflections off obviously switches off the reflections in the ControlPanel box. This can actually speed up slower systems. In Windows 95 you may not notice the shades at all, as the display relies on special Microsoft System files. Get System Colors exclusively uses colors from the Windows System files. Get Default Colors resets the color scheme. If you dont like all these bright colors on your screen, rest assured: Even with reflections set to off, the display will be no heavier on your processor than the usual gray of Windows.
Scene Memory-Function and choice of cards. Digital mixers call this function TotalRecall PC-users will be familiar with loading and saving. The Scene-button on the right of the ControlPanel allows you to save (Save), load (Load) or even delete older scenes (Delete). Press cancel, and you will leave the box with no changes.
Also on the right of the card is the card-selection box (Select). Here you can switch the display to a multi-card setup. By the way, the Scene Memory Function always saves settings for all cards.

MediaPlayer.

To give you the right player for the right format at the right time, we have included a complete version of the popular WinJey. WinJey plays just about every audio-format, your computer can handle:
MP3 - MPEG Audio Layer 3 (requires only 16% system resources on Intel Pentium 200MMX), MP1 and MP2 Variants of the MPEG-format, WAV and VOC the most common and most important, and the most uncommon and therefore least important, but one of the oldest digital audio format, MOD, S3M, XM, IT and other Tracker-formats, MID Standard MIDI file format, CDA Analogue playback of audio CDs.
The software also offers Skin-Support allows you to change the look of your player completely. You can find skins on the internet @ www.winjey.com.

Emagic microLogic AV.

We are pleased to offer you Emagics Logic, one of the most successful Audio-/MIDIsequencers, currently in version 4.1, which is even more powerful. For the few of us, who dont yet know one of the worlds most successful sequencers: Logic Allows you to record and edit MIDI and audio data. Logic offers you notation, various MIDI and Audio editors, as well as synchronization to video signals. Especially the audio-side of MicroLogic AV is well equipped with, full 24-bit/96 kHz support, real-time effects and control. Newly added in version 4.1 is support for EWS88 ASIO drivers, as well as the possibility to use Logic Audio Device Setup Manager to chose your own driver combination (Which is especially helpful, if you are using multiple EWS88s in one system).

Further information on MicroLogic AV can be found online. You can even download the original manual. The documentation is supplies as a.PDF-file on the EWS88-CD.
Samplitude Project the audio editor.
SEKDs award-winning Audio Editing Suite Samplitude allows you to record and edit your compositions in a professional manner, on multiple tracks with up to 24-bit resolution and 96 kHz sampling-rate. Unlike MicroLogic AV, Samplitude is foremost an audio editor. Cut and paste, volume changes, fades, cross fades, dynamics, Looping, EQ, Sample conversion, everything is included.
Further information on Samplitude can be found online. You can even download the original manual. The documentation is supplies as a.PDF-file on the EWS88-CD.
There was a time, when music was still hand-made. :-)

BuzZ ThE tRaCker.

A Freeware-toy with this card?! What the.?! Well, one reason why we have chosen to include this program in our package is because it is Freeware free of charge. Furthermore, we would like to introduce you to a sound tool, which leaves all the current sound card clichs behind. Our department for fun at work have chosen BUZZ to introduce musicians to a new way of sound production, which can be a valid alternative to conventional sequencers.
BUZZ takes you back to the dawn of sequenced pop music It has, however, a thoroughly modern and optimized code for using Windows. BUZZ is a audio program akin to trackers which used to be around in the mid 80s on machines like the Commodore AMIGA and, later, on DOS-systems. In BUZZ you will be programming music, which sounds worse than it actually is: You can choose an instrument, called a generator and start programming patterns. A pattern is 1 or more bars of notes. These patterns can then be arranged to a complete song.
The great thing about BUZZ is that the patterns not only contain note information, but also information on the instruments. And these instruments dont have to be just players for WAVdata, but also physical modeling, Virtual Analogue Synthesizer, effects and much more. There are also options to import an external signal, as well as using VST plugins. Basically, this program is absolutely terrific ;-). BUZZ benefits from its open program code, which allows for third-party software to join in the fun. Obviously, the number 1 medium for information on generators, songs, etc. Is the internet. Here are only a few web-pages where you can start your research:

English English English German

If you like BUZZ, you are welcome to support the work on this project. You can find out how @
http://www.fh-zwickau.de/~maz/products/german/index.html (below).
Unfortunately, there is currently no manual. But then again, you probably wouldnt want to read it anyway ;-). The TerraTec Team has prepared a tutorial and included in the code. TUTORIAL ENGLISH.BMX can be opened in BUZZ. When running BUZZ, simply press F10.
Important: BUZZ is quite a freaktool. It is freeware and continues to live on through its thousands of supporters worldwide. BUZZ is not, and will hopefully never be, a finished product. This means that the software is constantly being improved. It can crash, and it can generate frequencies, which dont sound nice at all, and can even be painful. The TerraTec Team cannot offer technical support for BUZZ and accepts no liabilities. Use of this code is at your own risk. But every BUZZer has gone through this, because its worth it.

HOTSTUFF.!!!-contents.

On the CD ROM for the EWS88 we have compiled a number of other programs, tools and files. Have a look, there might be something just for you.
Most programs here are shareware. Please support the shareware-principle and pay your share, if you like the programs. Thank you.
Tips and useful information.

Connections.

The connection-options of the Audio Systems EWS88 are huge. Professionals will know how to connect the card with the external equipment: AUX sends, sub-groups, Tape channels and Inserts are things you are certainly familiar with. As the EWS 88 is principally no different to a tape-recorder, you can use most of the routings you already know from you console. Here is a brief summary for beginners. (Just) get started with the EWS88 MT. On of the simplest applications is to run the EWS88 MT as a normal (Stereo) Sound card. Outputs 1+2 are to be connected to your monitoring system (hi-fi-System; AUX-, Video, Tape or CD-input). Inputs 1+2 are to be connected to the device, from which you wish to record. Digital devices like MiniDisk or DAT-recorder can also be connected to the card, as well as any MIDI Instruments you may have. Always make sure: OUT goes to IN and vice versa. This also applies to MIDI If you want to know more about the ControlPanel, refer to page 53. The EWS as a mixing desk. The EWS88 MT gives you 8 analogue inputs (32, if you cascade 4 EWS88 MST!), And you could use this card in place of a mixing desk, though there are no complex routings (i.e. subgroups), equalization or effect-sends on offer. But simply merging all you channels using the EWS88, makes this a viable alternative. Fast PCs could even include the functions of your sequencer. For example, Cubase VST allows you to mix the cards input with (near) real-time effects. EWS88 D and Mixdown You might want to use the EWS88 D for transferring an external ADAT-signal to a different format. For starters, you could transfer all 8 audio-channels directly to your hard-drive and start editing them in your Wave-editor. The flexible routing and the digital mixer in the EWS88 allows you to mix all 8 channels and send them directly to the S/PDIF output and record these with a DAT-Recorder for instance!

Hard disks and storage capacity Now you suddenly have a great recorder, which allows you record audio-signals to a previously impossible standard. Of course there is as with most things in life a catch: As the sound quality increases, so does the need for hard disk space. If you want to dip your toes into 24-bit recording, you should incorporate a large, and more importantly, fast enough harddrive. To give you an idea of the amount of data your hard disk has to deal with in these circumstances, here is a simple formula which allows you to calculate your requirements.
Number of channels x resolution in BIT x sampling frequency in Hz divided by 8 divided by 1024 and, again, divided by 1024 = MB/s For one stereo signal (two tracks) with the highest possible resolution, you will achieve the following result in MB/s: 2 x 24 x 96000 / 8 / 1024 / 1024 = ~ 0,55 Slightly more than half an MB. This translates into 33 MB per minute. Lets take a look at a typical multi-track scenario: 8 channels take up about 2.2 MB per second. An average arrangement of, lets say, 20 channels (of which we play back 16 at any one time), will require roughly 5 MB per second. And, of course, this is only for play-back. Naturally, we are not trying to put you off such high resolutions, but we encourage you to take a good look at your requirements. Not every application justifies such a high resolution. Very often, the difference between 48 kHz and 96 kHz is negligible.
