NAME

       bplay, brec - buffered sound recording/playing

SYNOPSIS

       bplay  [-d  device]  [-B  buffersize] [-S] [-s speed] [-b bits] [[-t secs] | [-T samples]]
       [[-j secs] | [-J samples]] [-D level] [file]

       brec [-d device] [-B buffersize] [-S] [-s speed] [-b bits]  [[-t  secs]  |  [-T  samples]]
       [-r|-v|-w] [-D level] [file]

DESCRIPTION

       bplay  copies  data  from  the  named  sound file (or the standard input if no filename is
       given) to the audio device.

       brec copies data from the audio device to the named sound file (or the standard output  if
       no filename is present).

       These  programs are intended to be drop-in replacements for the vplay and vrec programs by
       Michael Beck (beck@informatik.hu-berlin.de).

   OPTIONS
       -B buffersize
              Use the supplied audio buffer size instead of the default.

       -d device
              Use the supplied audio device instead of the default.

       -S     Sound file is stereo.

       -s speed
              The speed in samples per second.

       -b bits
              The number of bits per sample. Only 8 and 16 are currently supported.

       -t secs
              The number of seconds to be played or recorded.

       -T samples
              The number of samples to be played or recorded.

       -j secs
              When playing, the number of seconds to skip at the beginning of  the  input  before
              playing.

       -J samples
              When  playing,  the  number of samples to skip at the beginning of the input before
              playing.

       -r     When recording, write raw sound file.

       -v     When recording, write Creative Labs VOC sound file.

       -w     When recording write Microsoft Wave sound file. Note that the WAVE file  format  is
              limited  to  4GiB  filesize.  Recording  more data is possible, but the length info
              won't be consistent.

       -q     Quiet mode.  No messages are displayed.

       -D level
              Print debug information to stderr. Debug level ranges from 0 to 2, where  0  is  no
              debug information.

FILES

       /dev/dsp The audio device.

BUGS

       The -t, -T, -j and -J options may do strange things when playing VOC files.

       There  are  limitations  on  recording  VOC format files - specifically VOC files are only
       recorded in the 1.20 version of the format, which some player programs may choke on. There
       is  also currently a limit of around 16M on the size of a VOC file which will be recorded.
       This is probably not a problem since I don't think anybody really uses VOC files anymore.

       This program prefers to run setuid root. This is because it wants to use setpriority()  to
       run  at  the  highest  possible priority, and also locks down the buffers it uses to avoid
       them being swapped out.
