Compression:
This list box selects specific compression formats for re-
cording, and displays the compressed format of the file
currently playing. Each audio board has specific compres-
sion formats that it supports. If the compression format
selected is unavailable on the audio board, a message box
similar to Figure 8 will appear.
To select the compression ratio of an MPEG file, double
click on MPEG in the Compression list. A drop-down
menu displays the bitrates available for the current sample
rate.
Channels:
These buttons select mono or stereo recording, and dis-
play the number of channels of the current file.
VU Meters:
The VU meters show the relative signal of the current file
that is being recorded or played.
Wave Device:
If your driver is configured for dual devices or your com-
puter has more than one Antex audio board, this drop
down list box will allow selection of the specific de-
vice/board to be used for recording and playback. Each
file must be assigned a unique device/board.
