Filters

Every filter call applies right away, so there’s no .apply(). Calls in the same tick share one request:

// One PATCH to Lavalink, not three
await Promise.all([
  player.filters.bassBoost('high'),
  player.filters.nightcore(),
  player.setVolume(90),
]);

Try the Filter LabToggle filters and see the exact payload Raya sends to Lavalink.

Presets

await player.filters.bassBoost('medium'); // 'off' | 'low' | 'medium' | 'high' | 'extreme' | 0-1
await player.filters.nightcore();         // nightcore(false) turns it off
await player.filters.vaporwave();
await player.filters.eightD();            // eightD(true, rotationHz)
await player.filters.karaoke();
await player.filters.soft();
await player.filters.tremolo();
await player.filters.vibrato();

bassBoost only changes equalizer bands 0 to 4, so it combines with an equalizer preset.

Equalizer

await player.filters.setEqualizerPreset('rock');
// flat, bass, pop, rock, electronic, classical, soft, treble, vocal

await player.filters.setEqualizer([
  { band: 0, gain: 0.2 },  // band 0-14, gain -0.25 to 1 (clamped)
  { band: 1, gain: 0.15 },
]);
await player.filters.clearEqualizer();

Speed, pitch and more

await player.filters.setSpeed(1.25);
await player.filters.setPitch(0.9);
await player.filters.setRate(1.1);
await player.filters.setTimescale({ speed: 1, pitch: 1.2, rate: 1 });
await player.filters.setVolume(1.5);   // 0-5 multiplier, separate from player volume
await player.filters.setRotation({ rotationHz: 0.3 });
await player.filters.setLowPass({ smoothing: 20 });
await player.filters.setKaraoke(null); // null removes a filter

Also available: setTremolo, setVibrato, setDistortion, setChannelMix.

Note

Timescale changes also affect player.position, so progress bars stay accurate at nightcore speed.

Bulk changes

await player.filters.set({ timescale: { speed: 1.2 }, rotation: { rotationHz: 0.2 } }); // replace all
await player.filters.patch({ rotation: null, lowPass: { smoothing: 15 } });            // merge
await player.filters.clear();

Plugin filters

Filters from Lavalink plugins (for example LavaDSPX) go under pluginFilters:

await player.filters.setPluginFilter('echo', { /* shape defined by the plugin */ });
await player.filters.setPluginFilter('echo', null); // remove

Reading state

player.filters.active;          // ['equalizer', 'timescale']
player.filters.value;           // the payload sent to Lavalink
player.filters.speedMultiplier; // speed × rate
