line in audio send over wifi possible?

Postby Espe21 » Sat May 19, 2018 6:47 am

My imagination is:
Connect the line out (or speaker out) from an audio device (like mp3 player) to an esp32. The esp32 send it over wifi to another esp32 and plays the audio. Mp3 player -> esp32 ....wifi....-> esp32 -> amplifier -> speaker

Is this possible? what do i need? have you links to similar projects?

Thank you for help.

At the highest level, it feels like you have a puzzle in two halves. The first part is receiving an analog signal and encoding that as a digital stream (your incoming signal) and then a second part which is taking a digital stream and turning that back into analog output or PCM output signal. The simplest part is streaming the data from the source to the destination over a network protocol. Sorry ... not familiar with existing projects that work with audio.
