WaveHeader

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

varheader=require("waveheader");//write to a normal fs.createWriteStreammyFileStream.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.

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
