# Music Filters and Audio

> Change bass, 8D audio, reverb, nightcore, playback speed, volume, and audio quality in Scrump Music.

Scrump can change how the shared queue sounds with audio filters, playback speed, and volume controls. These changes affect everyone listening in the active voice channel.

## Open the filters panel

Use the **Filters** button on `/now-playing` or `/queue view` to open a compact control panel in the channel. The panel shows which presets are on and lets listeners toggle bass boost, 8D audio, reverb, and nightcore without running another command.

Playback speed appears in the same panel. Use the **−0.25x** and **+0.25x** buttons to adjust it, or **Reset to 1x** to return to normal speed. The controls stop at Scrump's supported range of 0.1x to 3.0x.

Running any `/filters toggle` or `/filters song-speed` command also opens the updated panel after the change, so you can continue adjusting the sound from one place.

## Toggle an audio filter

| Command                      | Sound                                   |
| ---------------------------- | --------------------------------------- |
| `/filters toggle bass-boost` | Emphasizes lower frequencies            |
| `/filters toggle 8d-audio`   | Moves the sound around the stereo field |
| `/filters toggle reverb`     | Adds a spacious echo effect             |
| `/filters toggle nightcore`  | Applies a faster, higher-pitched preset |

Run the same command again to turn that filter off. Multiple filters can produce a much stronger effect than one filter by itself.

## Change playback speed

* `/filters song-speed fast` sets playback to 1.25x.
* `/filters song-speed slow` sets playback to 0.75x.
* `/filters song-speed custom speed:` accepts a value from 0.1x to 3.0x.

```text theme={null}
/filters song-speed custom speed:1.5
```

Speed changes affect the active playback session. Use `1.0` as the custom speed to return to normal.

## Change volume

Run `/player volume volume:` with a value from 1 to 300.

```text theme={null}
/player volume volume:80
```

100% is the normal level. Values above 100% amplify the audio and may cause distortion, especially when combined with bass boost.

## Enhanced queue requirement

Filters, speed, volume, and full-queue looping require an enhanced queue. A queue is enhanced when either:

* The server has Plus or Pro; or
* A member with Scrump Blue is currently participating in that voice channel.

Scrump Blue queue benefits last only while the Blue member is participating. If the queue returns to standard access, Scrump removes enhanced filters, restores 1.0x speed and 100% volume, turns off queue looping, and returns to the free queue limit and audio target.

## Audio quality

| Queue access                              |                  Target audio quality |                  Maximum queue size |
| ----------------------------------------- | ------------------------------------: | ----------------------------------: |
| Free server without an active Blue member |                               64 kbps |                           250 songs |
| Plus or Pro server                        |                        Up to 256 kbps |                        10,000 songs |
| Queue with a participating Blue member    | Up to 256 kbps while they participate | 10,000 songs while they participate |

The actual audio quality cannot exceed the Discord voice channel's bitrate. A server boost level or channel setting can therefore limit the effective bitrate even when Scrump targets 256 kbps.

<Note>Changing Scrump's volume or adding filters cannot improve the quality of the original recording. If one song sounds poor while others do not, try another version of that song.</Note>
