The Antex Demo program allows basic recording and playback of .WAV files in any of the compression
formats available on the Antex Audio board you have installed in your system.
Sample Rate
This list box selects specific sample rates for recording, and displays the sample rate of the file
that is currently playing. Not all sample rates are available for each compression format. If a
sample rate is invalid for a specific compression format, the program will display a message box
similar to Figure 11.
Compression:
This list box selects specific compression formats for recording, and displays the compressed
format of the file currently playing. Each Audio Adapter has specific compression formats that it
supports. If the compression format selected cannot be used on the Audio Adapter that you
have, a message box similar to Figure 11 will appear.
To select the compression ratio of an MPEG file, double click on

A drop-down menu displays the bitrates available for the current sample rate.
