Hey everyone. Is it possible to send raw audio (or compressed in whatever format) through HTTP or Websockets? I am testing an implementation and wanted to do some tests but wanted to skip ESPhome all together. I’m not really sure how to search this so I’m sorry if there’s already a similar question somewhere.

Probably Wyoming protocol will help? It sends raw PCM. But you have to implement the pipeline interaction for that to work...

What is PCM?

#

Yeah, pipeline should be set up normally, just wanted to send the audio in a different way
