6 - Using High Sample Rates
Overview
E-MU 1820M/1820/1212M PCI Digital Audio System

Example: Selecting a 176/192k Session
The possible input configurations are selected by choosing a session template
containing the desired I/O from the
New Session
window. Once you have selected one
of the three session types, you will not be able to change to another type without
starting a new session.
1.
Select
New Session
from the PatchMix DSP toolbar.
2.
Choose the
176k/192k
tab.
3.
Select the Template
that meets your requirements and click
OK.
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.
