NAME
pad -- Pseudo audio device driver
SYNOPSIS
pseudo-device pad audio* at audiobus?
DESCRIPTION
pad is a pseudo-device driver which provides support for feeding back PCM data from consumers of an audio(4) device to userland. The raw PCM data readable from /dev/padN is encoded in stereo little- endian 16-bit linear PCM at 44100 Hz.
FILES
The pad pseudo-device driver receives data from /dev/audioN and feeds the raw PCM output to /dev/padN. /dev/audioN is created once /dev/padN is opened. /dev/audioN /dev/padN
EXAMPLES
The following example streams an MP3 to an Apple AirTunes compatible device: $ rtunes - < /dev/pad0 & $ mpg123 -a /dev/audio1 mozart.mp3 Record the output of an application (in this case, audioplay): $ ffmpeg -f s16le -ar 44100 -ac 2 -i /dev/pad0 output.wav $ audioplay -d /dev/audio1 input.wav
