Audio filters
Filters change how the current track sounds. They apply to the player, not to one track, so they stay on until you clear them.
Everything on this page requires a vote or Premium, and the Filter Effects DJ permission when DJ mode is on.
The toggles
Each of these flips on and off. Run the same subcommand again to undo it.
| Command | Effect |
|---|---|
/filter bassboost | lifts the low frequencies |
/filter nightcore | speeds the track up and raises its pitch |
/filter demon | slows it down and drops the pitch hard |
/filter 8d | rotates the sound around your head |
/filter karaoke | tries to pull the vocals out |
/filter vibrato | adds a pulsing wobble to the pitch |
/filter vaporwave | listed, but currently applies no audio effect |

Filters stack. Nightcore plus bassboost is a valid, loud combination.
The dials
| Command | Range | Effect |
|---|---|---|
/filter speed speed: 1.5 | 0.1 to 2 | playback tempo |
/filter pitch pitch: 0.8 | 0.1 to 2 | pitch, without touching tempo |
1 is normal for both. /filter speed is the only filter that works while
nothing is playing, so you can set the tempo before the next track starts.
Clearing

/filter clear removes every filter at once and puts speed and pitch back to
normal. Faster than untoggling them one by one when a track sounds wrong and
you are not sure what is on.
Filters and restarts
The filters you have on are saved with the player. If the bot restarts mid session and recovers your player, the same filters come back on with it.
From the web player
The web player exposes the same filters as switches. It applies the same vote or Premium requirement and the same DJ permission, so nothing you cannot do with a command becomes possible there.
