The Most Important Ones: Waveplay And Waverecord; Multiple Channels With Interleaved; Systemsound Drivers - TerraTec EWS88 MT Manual

A closer look at the different drivers and "devices".

The most important ones: WavePlay and WaveRecord.

The most important drivers will be "WavePlay" for audio playback and "WaveRec" for
recording. The driver names are identical to the ones which appear in different sections of the
ControlPanel and refer to the 10 possible recording-and playback channels of the EWS88. The
ControlPanel allows you to mix all WavePlay channels or to route them to the 10 outputs (8 x
analogue or ADAT, 2 x co-axial) on your card. When recording, the driver names indicate the
input pair, which receives the audio signal. "WaveRec S/PDIF (1)" is the digital input of the first
EWS88. And of course there is the recording driver "Digital Mixer". This will mix all digital
signals at once (refer to page 54). As a result, it can be used for digitally resampling of all
signals.
There are further hints and tips in the chapter "ControlPanel." from page 53.

Multiple channels with interleaved.

The driver "Interleaved Play" (or Rec.) is a driver particularly for applications which
send/receive audio data according to the "Interleaved" standard. Windows-Wave-Format not
only supports stereo data, but up to 8 audio channels, which can all be grouped together (in a
file, for instance). This is particularly useful for multi-channel live performances: simply
arrange 8 audio channels in a hard disk recording program (like CoolEdit PRO) in a single
Interleaved WAV-File and play back on a system, which also supports "Interleaved".

SystemSound drivers.

A real treat turned out to be the integrated "System WavePlay" driver. This routed the sound
directly to the backplate of the EWS88. Room restrictions meant that we could only
accommodate a mini-jack connection. Audio test results and its performance, however, show
that this is perfectly fine. A high quality 18-bit converter delivers powerful playback.
You can use this output for Windows SystemSound or as an independent output for audio
editors or software synthesizers. The latter can profit from lightening fast DirectSound
implementation in its driver. In Generator you can easily achieve a latency of less than 10ms!
The "System WaveRec" allows you to record directly from your 2 CD drives (see page 42).
