.SH DESCRIPTION
.I Auplay
plays each
.I file
in turn on the audio device
.B /dev/audio
(see
.IR audio (3)),
setting the device's characteristics in
.B /dev/audioctl
to match those of the
.IR file .
It uses
.I stream
(see
.IR sys-read (2))
to stream the data to the device at high priority.
All files played must be in `Inferno audio format',
as defined by
.IR audio (6).
.PP
.I Auhdr
writes the header of each Inferno audio
.I input
file to the standard output.
The header describes the data in a form that can be written directly to
.BR /dev/audioctl
to set the device's characteristics.
.PP
.I Raw2iaf
converts the
.I input
file, adds an appropriate header to describe the data
in the Inferno format, and writes the result to the
.I output
file.
The options tell how the bytes in the input file should be interpreted:
.TP
.B -8
rate is 8000 Hz
.TP
.B -1
rate is 11025 Hz
.TP
.B -2
rate is 22050 Hz
.TP
.B -4
rate is 44100 Hz
.TP
.B -m
mono (one channel)
.TP
.B -s
stereo (two channels)
.TP
.B -b
each sample in each channel is one byte (unsigned)
.TP
.B -w
each sample in each channel is 16-bits (little-endian)
.TP
.B -a
input is a-law encoded
.TP
.B -u
input is \(*m-law encoded
.TP
.B -p
input is PCM encoded
.PP
.I Wav2iaf
reads the
.I input
file, which must be in Windows WAV format and encoded using PCM,
and converts the data to Inferno format
on the standard output.
