Audio frequency and resolution representation on GPIOs


Is it possible to change GPIOs states depending on audio file frequency and resolution? It could be used to connect displays for showing frequency and resolution. It would be nice feature.

Welcome to Volumio!

Sure that would be possible, sounds like an idea for a plugin :slight_smile:

Yep, you can do it via a plugin

Thank you for replies.

Does a suitable plugin exist? If it does not, please advise some links / examples of how plugins are created.


I don’t believe so - but you could look again in Volumio Plugins Collection

As for writing a plugin - the docs might be a bit sparse, but it is a good start Writing A Plugin - Volumio Documentation

You could also peek into some other plugins from the GitHub - volumio/volumio-plugins repository for inspiration :slight_smile:

Thank you.
