AUPLAY(1) AUPLAY(1)
NAME
auplay, auhdr, raw2iaf, wav2iaf - basic audio output and
conversion
SYNOPSIS
auplay file ...
auhdr file ...
raw2iaf [ option ... ] [ -o output ] input
wav2iaf [ input ]
wav2iaf
DESCRIPTION
Auplay plays each file in turn on the audio device
/dev/audio (see audio(3)), setting the device's characteris-
tics in /dev/audioctl to match those of the file. It uses
stream (see 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 audio(6).
Auhdr writes the header of each Inferno audio input file to
the standard output. The header describes the data in a
form that can be written directly to /dev/audioctl to set
the device's characteristics.
Raw2iaf converts the input file, adds an appropriate header
to describe the data in the Inferno format, and writes the
result to the output file. The options tell how the bytes
in the input file should be interpreted:
-8 rate is 8000 Hz
-1 rate is 11025 Hz
-2 rate is 22050 Hz
-4 rate is 44100 Hz
-m mono (one channel)
-s stereo (two channels)
-b each sample in each channel is one byte (unsigned)
-w each sample in each channel is 16-bits (little-endian)
-a input is a-law encoded

-u input is M-law encoded
-p input is PCM encoded
Wav2iaf reads the input file, which must be in Windows WAV
format and encoded using PCM, and converts the data to
Inferno format on the standard output.
