The special name .Dq - 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. .Sh OPTIONS The following options are available: .Bl -tag -width 123456 .It Fl B Set the write block size to .Ar buffersize . The default value is the play.buffer_size of the audio device. .It Fl b Set the balance to .Ar balance . This value must be between 0 and 63. .It Fl c When combined with the .Fl f option, sets the number of channels to its argument. .It Fl d Set the audio device to be .Ar device . The default is .Pa /dev/sound . .It Fl e When combined with the .Fl f option, sets the encoding to its argument. Possible values are .Cm mulaw , .Cm ulaw , .Cm alaw , .Cm slinear , .Cm linear , .Cm ulinear , .Cm adpcm , .Cm ADPCM , .Cm slinear_le , .Cm linear_le , .Cm ulinear_le , .Cm slinear_be , .Cm linear_be , .Cm ulinear_be , .Cm mpeg_l1_stream , .Cm mpeg_l1_packets , .Cm mpeg_l1_system , .Cm mpeg_l2_stream , .Cm mpeg_l2_packets , and .Cm mpeg_l2_system . .It Fl f Force playing, even if the format is unknown. The .Fl f flag can be used in addition with the .Fl c , .Fl e , .Fl P , and .Fl s flags to change the number of channels, encoding, precision, and sample rate. .It Fl h Print a help message. .It Fl i If the audio device cannot be opened, exit now rather than wait for it. .It Fl P When combined with the .Fl f option, sets the precision to its argument. This value must be either 4, 8, 16, 24 or 32. .It Fl p Set the output port to .Ar port . The valid values of .Ar port are .Dq speaker , .Dq headphone and .Dq line . .It Fl q Be quiet. .It Fl s When combined with the .Fl 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. .It Fl V Be verbose. .It Fl v Set the volume (gain) to .Ar volume . This value must be between 0 and 255. .El .Sh ENVIRONMENT .Bl -tag -width AUDIOCTLDEVICE .It AUDIOCTLDEVICE the audio control device to be used. .It AUDIODEVICE the audio device to be used. .El .Sh EXAMPLES Play a raw dump taken from an audio CD ROM: .Pp .Dl "audioplay -f -c 2 -P 16 -s 44100 -e slinear_le filename" .Pp The .Xr audioctl 1 program can be used to show the available supported encodings: .Pp .Dl "audioctl encodings" .Sh NOTES .Nm can be used to play Sun/NeXT audio files, and also RIFF WAVE audio files. .Nm can be configured in a web browser as the program to use when playing audio files. .Pp In addition to the audio driver encodings list in the EXAMPLES section, .Nm 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 .Nm converts the floating point data into signed linear samples before they are passed to the chosen audio device. .Sh ERRORS If the audio device or the control device can not be opened, an error is returned. .Pp 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. .Sh SEE ALSO .Xr audioctl 1 , .Xr audiorecord 1 , .Xr audio 4 .Sh HISTORY The .Nm program was first seen in SunOS 5. The .Nx .Nm was first made available in .Nx 1.4 . Support for RIFF WAVE recording was introduced in .Nx 1.6 . Support for RIFF WAVE IEEE floating point data was introduced in .Nx 10.0 . .Sh AUTHORS The .Nm program was written by .An Matthew R. Green Aq Mt mrg@eterna.com.au .
