VPLAY(1)

NAME
vplay, vrec - play and record sound files.

SYNOPSIS
vplay [ options ] [ filename ]

DESCRIPTION
vplay can play and record CREATIVE LABS VOICE files (fully supported), MICROSOFT WAVE files (PCM coded) and raw audio data files.
On non-stereo cards (SB 1.0 - 2.0) 8 bit stereo files will be played as mono (the first channel is used). On non-16-bit cards, 16 bit WAVE files will be played as 8 bit (you either can play 16-bit stereo WAVE files on a SB 1.0 or thru PC-Speaker :-), or you got to buy ...). The options for speed, time etc. take only effect if raw data files are played. VOC and WAVE files include this information in their headers/internal structure.

OPTIONS

-V  Print version information on standard output then exit successfully.

-S  Stereo output (default is mono).

-s Hz
    Sets the speed (default is 8 kHz). If the speed is less than 300, it is multiplied by 1000.

-t seconds
    Sets the recording (or playback) time in seconds. Default is no time limit.

-b bits
    Sets sample size (bits/sample). Possible values are 8 and 16 (default 8).

-o device
    Change the the audio device. Default is /dev/dsp

-v  Record a CREATIVE LABS VOICE file (default).

-w  Record a MICROSOFT WAVE file.

-r  Record raw data without header.

-q  Quiet mode.

BUGS
The -t parameter is applied to each files. For example
    vrec -r -t 1 a b c
records one second of audio data to each of the files a, b, and c and
    vplay -t 1 a b c
plays the first second of each of the files a, b and c (if it's raw audio).
Don't use higher recording speeds than your card supports. This error is not always detected by the sound driver. The full RIFF specification isn't supported (I'm not yet working on it, but indent to do soon), so some WAVE files may not work.
