audioplay
program copies the named audio files, or
the standard input if no files are named, to the audio device. The special
name “-” is assumed to mean the standard input. The input files
must contain a valid audio header, and the encoding must be understood by the
underlying driver.

option, sets the number
of channels to its argument.-d

.-f
-f
flag can be used in addition with the
-c
, -e
,
-P
, and -s
flags to change
the number of channels, encoding, precision, and sample rate.-h
-i
-n
-P
-f
option, sets the
precision to its argument. This value must be either 4, 8, 16, 24 or
32.-p
-q
-s
-f
option, sets the sample
rate to its argument. This value must be a valid value for the audio
device or an error will be returned.-V

The audioctl(1) program can be used to show the available supported encodings:
audioctl encodings
audioplay
can be used to play Sun/NeXT audio files, and
also RIFF WAVE audio files. audioplay
can be
configured in a web browser as the program to use when playing audio files.
In addition to the audio driver encodings list in the EXAMPLES
section, audioplay
supports playing IEEE floating
point data in RIFF WAVE audio files (with one caveat that the floating point
size must be native). In this case audioplay
converts the floating point data into signed linear samples before they are
passed to the chosen audio device.
If an invalid parameter is specified, an error is returned. The set of valid values for any audio parameter is specified by the hardware driver.
audioplay
program was first seen in SunOS 5. The
NetBSD audioplay
was first
made available in NetBSD 1.4. Support for RIFF WAVE
recording was introduced in NetBSD 1.6. Support for
RIFF WAVE IEEE floating point data was introduced in NetBSD
10.0.
