Writing a wav file: writewav

The writewav command writes sound data to a wav file.

writewav takes two arguments:
- filename, the name of a file.
- s, the sound data. This can either be in the same format as that returned by the readwav command or (for a mono sound) a list of the digital data of the sound which will use the default parameters (16 bits, 44100 Hz).
writewav(filename,s) writes the sound to the file filename.

Example.
Input:

writewav("la.wav",2^14*sin(2*pi*440*soundsec(1)))

Output: There will be a file la.wav containing a sound of frequency 440 Hz sampled 44100 times per second.
