WAVPLAY(1) General Commands Manual WAVPLAY(1) NAME wavplay, wavrec - play and record WAV files SYNOPSIS wavplay [-h,--help] [-q] [-s rate] [-S] [-M] [-b bits] [-i] [-k ipc-key] [-R] [-l] [-u] [-L] [-U] [-V,--version] [input-files] wavrec [-h,--help] [-q] [-s rate] [-S] [-M] [-b bits] [-t secs] [-k ipc- key] [-R] [-l] [-u] [-L] [-U] [-V,--version] [output-file] DESCRIPTION wavplay plays a WAV format file to the audio device (by default /dev/dsp ) reading WAV parameters from the input file header. (Command-line options will override these defaults, if you know better or for special effects.) wavrec samples the audio device and writes a WAV file. Command-line op- tions provide complete control over the resolution and duration of sam- pling. Both wavplay and wavrec allow the audio device to be locked for exclusive access. OPTIONS -h print a short summary of options. --help same as -h. -q quiet mode, suppress messages. -s rate set sampling rate in Hz. The default is 8000 Hz. -S set stereo mode (overrides -M). This is the default. -M set mono mode (overrides -S). -b bits set the number of bits per sample (8/12/16). The default is 16. -t secs set time limit for recording. The default is 10 seconds. -i don't play, just display WAV file header information. -k key specify the IPC key for device-locking semaphores. The default is 0x33333333. -R remove and recreate device-locking semaphores. -l lock the audio device for playing. -u unlock the audio device for playing. -L lock the audio device for recording. -U unlock the audio device for recording. -V display version and copyright information. --version same as -V.
