Overview

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.
