¦ Note
When capturing to a Matrox .mp4 file with simultaneous capture to a
Matrox MPEG-2 I-frame .avi file, stereo audio will be embedded in the .mp4
and .avi files. When capturing to a Matrox .avi file only, audio is always
captured to separate .wav files, and the channels that you choose to save to the
first stereo .wav file or first two mono .wav files will be embedded in the
associated .avi file.

with separate .wav files, the channels that you choose to save to the first

When capturing to separate .aac or .wav files, you can select up to four

stereo channels or up to eight mono channels, depending on the type of
audio being captured. Select None for the particular files that you
don't want, or click the D (default) button for each Filename list if you
want to capture only channels 1 and 2. When Matrox MXO2 saves
separate audio files, it assigns a .Stereo or .Mono suffix to the base
name of the associated video file. For example, if you're capturing to
separate .wav files and your video file is named MyFile.001.264, the
associated stereo audio files will be named MyFile.001.Stereo1.wav,
MyFile.001.Stereo2.wav, etc.
