WaveHeader

====

Just generates a WAVE-file header, with the specified length as argument.

```javascript

var header = require("waveheader");

//write to a normal fs.createWriteStream

myFileStream.write(header(44100 * 8)); // 44100 khz * 8 seconds

// using options (all available options listed)

myOtherFileStream.write(header(22050 * 8) {

  sampleRate: 22050,

  channels: 2,

  bitDepth: 8

}); 

```

### Use with tonegenerator:

Also check out the module for generating tones as raw PCM data,

[tonegenerator](http://npmjs.com/package/tonegenerator).

### using the debug module

Waveheader uses the 'debug' module to clean the output a bit. If running your program from the command line, and you wanna see the size written to the header, do `DEBUG=waveheader node yourprogram.js`
