Audio Input to Output Copying Driver
Sometimes it’s useful to play back audio data from an input to an output in the back-
ground. This can be done by an audio copying driver.
7.8.1
Driver AUXPLAY.DL3
The AUXPLAY.DL3 driver reads data from
stdaudioin
and copies it to
stdaudioout
. While
seemingly trivial, it does so in the background, allowing the user to do other operations
while sound is being played back.
Normally the driver reports to
stdout
if there are input buffer overflows or output buffer
underflows. The amount of the overflows/underflows are given in stereo samples (so
e.g. +4800 at a sample rate of 48000 means 1/10s). The reports use the following
format:
AUXSPLAY: In ov4088
AUXSPLAY: Out und4034
To disable overflow and underflow reporting, give the ’q’ parameter to AUXSPLAY.DL3.
