aecho(1) aecho(1) 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.
