# `Rockbox.EqPreset`
[🔗](https://github.com/tsirysndr/rockboxd/blob/master/bindings/elixir/lib/rockbox/eq_preset.ex#L1)

Built-in equalizer presets for `Rockbox.Player.set_eq_preset/2`.

These mirror the C ABI `EqPreset::ALL` order:

| Atom              | Value |
| ----------------- | ----- |
| `:flat`           | 0     |
| `:acoustic`       | 1     |
| `:bass_boost`     | 2     |
| `:bass_reducer`   | 3     |
| `:classical`      | 4     |
| `:dance`          | 5     |
| `:deep`           | 6     |
| `:electronic`     | 7     |
| `:hip_hop`        | 8     |
| `:jazz`           | 9     |
| `:latin`          | 10    |
| `:loudness`       | 11    |
| `:lounge`         | 12    |
| `:piano`          | 13    |
| `:pop`            | 14    |
| `:rnb`            | 15    |
| `:rock`           | 16    |
| `:small_speakers` | 17    |
| `:treble_boost`   | 18    |
| `:treble_reducer` | 19    |
| `:vocal_boost`    | 20    |

`to_int/1` accepts either the atom or the raw integer, so callers can pass
whichever they prefer.
