Java-Music

The program generate raw PCM sound (64 bit, big endian)

This project was created under the huge impression of "Making Music with Haskell From Scratch" video.

As opposed to the @tsoding video with pure-functional approach, this project has been made (mostly) in OOP way.

Generate PCM sound

public static void main(String[] args) {
        Sound notes = notes(0.4).with(new VolumeFilter(0.3))
            .add(new Silence(1))
            .add(notes(0.5).with(new VolumeFilter(0.5)));

        SoundWriter writer = new SoundWriter(48000);
        writer.write(notes, "music/demo.pcm");
}

private static Sound notes(double noteDuration) {
        Filter notePressFilter = new PeakReleaseFilter(0.1, 0.9);
        return IntStream.range(-4, 4)
            .mapToObj(n -> new Note(noteDuration, n).with(notePressFilter))
            .reduce(new Track(), Track::add, Track::add);
}
