A bunch of lavaplayer audio filters implemented with native code forked from https://github.com/natanbc/lavadsp with mac m1 natives fixes

Getting Started

Installing

Replace VERSION with the version you want to use. The latest version can be found in the badge above.

Gradle

repositories {
    maven{ "http://maven.arbjerg.dev/releases" }
}

dependencies {
    compile "dev.arbjerg:lavadsp:VERSION"
}

Basic Usage

AudioPlayer player = manager.createPlayer();
player.setFilterFactory((track, format, output)->{
    TimescalePcmAudioFilter audioFilter = new TimescalePcmAudioFilter(output, format.channelCount, format.sampleRate);
    audioFilter.setSpeed(1.5); //1.5x normal speed
    return Collections.singletonList(audioFilter);
});

Chaining

Filters may be chained to merge their effects:

AudioPlayer player = manager.createPlayer();
player.setFilterFactory((track, format, output)->{
    TremoloPcmAudioFilter tremolo = new TremoloPcmAudioFilter(output, format.channelCount, format.sampleRate);
    tremolo.setDepth(0.75);
    TimescalePcmAudioFilter timescale = new TimescalePcmAudioFilter(tremolo, format.channelCount, format.sampleRate);
    timescale.setSpeed(1.5);
    return Arrays.asList(timescale, tremolo);
});

To dynamically choose which filters to use, you can see this example
