6 - Using High Sample Rates
Overview
E-MU Digital Audio System 91
WDM Recording and Playback Behavior
WDM recording and playback is supported at all PatchMix sample rates. The behavior of
the driver with respect to PatchMix sample rate is described below.
When PatchMix and the WDM audio content (.WAV file format, playback and record
settings in WaveLab. etc.) are both running at the same sample rate, and when a Wave
strip or send is present in the PatchMix mixer configuration, WDM audio will be played
or recorded “bit accurate” without sample rate conversion or bit truncation.
When running PatchMix at 44kHz/48kHz, if there is a mismatch between the WDM
playback audio content and the PatchMix sample rate, sample rate conversion is
performed, so that WDM audio will always be heard or recorded. Also, such non-native-
sample-rate audio is truncated to 16-bits.
When running PatchMix at 88.2kHz, 96kHz, 176.4kHz or 192kHz, WDM record or
playback audio content must be running at the same sample rate as PatchMix. If the
sample rates are mismatched, NO AUDIO will be produced or recorded. In other words,
the WDM driver does not perform sample rate conversion of any kind when PatchMix is
running at 88.2kHz, 96kHz, 176.4kHz or 192kHz.
