AUPLAY(1)AUPLAY(1)NAME
auplay, auhdr, raw2iaf, wav2iaf - basic audio output and conversion
SYNOPSISauplay 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 characteristics 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 stan‐
dard output. The header describes the data in a form that can be writ‐
ten 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 μ-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 stan‐
dard output.
