Reading from a WAV File
Code
Wav objRead1 = new Wav();
objRead1.readWav(inputFilename);
Hashtable< String, Long> propsOut = objRead1.getProperties(); // Gets the WAV file properties
double[][] signal = objRead1.getData("int"); // Can be 'int', 'long' 'double'
Output
System.out.println(objRead1.getProperties());
OUTPUT: {Channels=2, Frames=268237, ValidBits=16, BlockAlign=4, SampleRate=8000, BytesPerSample=2}
Writing to a WAV File
Wav objWrite = new Wav();
int channels = 2;
objWrite.putData(signal, channels, "int", outputFileName);
// Can be "int", "long" or "double' depending on the content of signal
