Scilab Function

wavwrite - writes .wav sound file

### Sequence d'appel

  `wavwrite(y,wavfile)`
  `wavwrite(y,Fs,wavfile)`
  `wavwrite(y,Fs,bits,wavfile)`

### Parametres

- `y` : real vector or matrix with entries in [-1,1].
- `wavfile` : string (The .wav extension is appended if no extension is given)
- `Fs` : integer, frequency sampling in Hz.
- `bits` : integer, number of bits in the encoding.
- `method` : string , `'mu'` (default) or `'linear'`, encoding method.

### Description

Utility function to save `.wav` sound file. `wavwrite(y,wavfile)` writes a sound file specified by the string wavfile. The data should be arranged with one channel per column. Amplitude values outside the range [-1,+1] are ignored. Supports multi-channel data for 8-bit mu-law, and 8- and 16-bit linear formats.

`wavwrite(y,Fs,wavfile)` specifies in `Fs` the sample rate of the data in Hertz.

`wavwrite(y,Fs,bits,wavfile)` selects the number of bits in the encoder. Allowable settings are bits=8 and bits=16.
