Your keyboard can make sounds! If you've got a Planck, Preonic, or basically any keyboard that allows access to the C6 or B5 port (`#define C6_AUDIO` and `#define B5_AUDIO`), you can hook up a simple speaker and make it beep. You can use those beeps to indicate layer transitions, modifiers, special keys, or just to play some funky 8bit tunes.

The audio code lives in [quantum/audio/audio.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/audio.h) and in the other files in the audio directory. It's enabled by default on the Planck [stock keymap](https://github.com/qmk/qmk_firmware/blob/master/keyboards/planck/keymaps/default/keymap.c). Here are the important bits:

If you add this to your `rules.mk`:
|
||||||
|
|

```
|
```
|
||||||
#include "audio.h"
|
AUDIO_ENABLE = yes
|
||||||
|
```
|

|
|

there's a couple different sounds that will automatically be enabled without any other configuration:

If you want to implement something custom, you can
|
||||||
|
|
||||||
|
```
|

#ifdef AUDIO_ENABLE
|

#include "audio.h"

"Rest style" in the method signature above (the last parameter) specifies if there's a rest (a moment of silence) between the notes.

## Music mode

The music mode maps your columns to a chromatic scale, and your rows to octaves. This works best with ortholinear keyboards, but can be made to work with others. All keycodes less than `0xFF` get blocked, so you won't type while playing notes - if you have special keys/mods, those will still work. A work-around for this is to jump to a different layer with KC_NOs before (or after) enabling music mode.
