sound

Obsolete. Please use playsnd(…) instead

Syntax

sound(y [,fs,bits,command)

Arguments

y

real vector

fs

real number, sampling frequency in sample per second (default value is 22050)

bits

real number, number of bits (unused)

command

Only used on Unix systems it gives the name of the command to use for playing sound (wav) files. The default value is aplay. If set /dev/audio then a 8 bits mu-law raw sound file is created and send to /dev/audio

Description

sound(…) is obsolete and will be removed from Scilab 2025.0. Please use playsnd(…) instead.

sound(y,fs)plays the sound signal given by matrix y (with sample frequency fs). In fact this function is just a wrapper for playsnd. Values in y are assumed to be in the range -1.0 <= y <= 1.0. Values outside that range are truncated. The number of rows of y gives the number of channels. sound(y) plays the sound at the default sample rate of 22050 sample per second. sound(y,fs,nbits) plays the sound using nbits bits/sample if possible (it is in fact unused). Most platforms support bits=8 or 16.

Examples

// a two channel signal
y = loadwave("SCI/modules/sound/demos/chimes.wav");
sound(y)
