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
SEE ALSO
HISTORY
The pad driver appeared in
NetBSD 5.0.
