NAME
aecho - An AF play/record client.
SYNOPSIS
aecho [-d device]
DESCRIPTION
aecho reads samples from stdin and sends the sound data to the audio server
for playback. It simultaneously records, with the record data sent to
stdout. The play and record operations are synchronized (i.e. the audio
time of the first playback sample is the audio time of the first record
sample).
aecho is useful for experimenting with room acoustics, and debugging audio
hardware.
OPTIONS
-d device
Specifies which audio device to use for playback and recording. If
device is not specified, aecho defaults to the first device that isn't
connected to the telephone.
ENVIRONMENT
AUDIOFILE specifies the host and server to use.
BUGS
There is no way to play back a file in preempt mode.
If you encounter a reproducible bug, please submit a problem report to
