WAV File

Writing WAV files

object WaveWriter {
    constructor WaveWriter();

    bool createWavFile( string filename, number samplerate, [channels: default 1]);
    bool addSamples( IQData samples );
    bool addSamples( FloatData samples );
    bool close();
}

Example

const SAMPLE_RATE = 48e3 ;

var wave = new WaveWriter();
if( wave.createWavFile('test.wav', SAMPLE_RATE, 1) == false ) {
    print('Cannot create file');
    exit(0);
}
var stereo_audio = DSP.tone( 440, SAMPLE_RATE, SAMPLE_RATE ); 
wave.addSamples( stereo_audio.getReal() );
wave.close();

.createWavFile

 bool createWavFile( string filename, number samplerate, [channels: default 1]);

Create a new WAV file with the following parameters:

filename : full path the file. If existing, the file will be overwritten.
samplerate: integer, the sample rate in Hz.
channels: 1 for MONO, 2 for STEREO

.addSamples

Append samples to the file.

for MONO WAV file (channels=1) : add only FloatData
for STEREO WAV file (channels=2) : add only IQData

 bool addSamples( samples );

.close

Close file on disk.
