# Audio
Your keyboard can make sounds! If you've got a Planck, Preonic, or basically any AVR keyboard that allows access to the C6 or B5 port (`#define C6_AUDIO` and/or `#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.
Your keyboard can make sounds! If you've got a Planck, Preonic, or basically any AVR keyboard that allows access to certain PWM-capable pins, 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.
Up to two simultaneous audio voices are supported, one driven by timer 1 and another driven by timer 3. The following pins can be defined as audio outputs in config.h:
Timer 1:
`#define B5_AUDIO`
`#define B6_AUDIO`
`#define B7_AUDIO`
Timer 3:
`#define C4_AUDIO`
`#define C5_AUDIO`
`#define C6_AUDIO`
If you add `AUDIO_ENABLE = yes` to your `rules.mk`, there's a couple different sounds that will automatically be enabled without any other configuration:
