I've been playing with Arduino for a few years, but I'm new to Bluetooth and streaming audio.
I'd like to develop (or assemble or buy) a device for recording stereo audio from a pair of Bluetooth headsets to a lossless file format on a micro SD card. I'm thinking this would be great for recording a podcast on the go with two people.
I'm guessing an ESP32 or similar could relatively easily record mono audio to an SD card.
Any recommendations on libraries and/or tutorials that could be used to piece together audio recording from a Bluetooth headset mic to lossless audio file on micro SD card? I'm thinking at least this first step should be relatively straightforward. :)
Any suggestions on how to integrate two stream of mono audio from two Bluetooth headset mics in order to combine to a single stereo audio file (using the streams as left and right channel)? I think this would require two Bluetooth receivers, and streaming the audio from each to a third processor for combining and saving the streams to a single stereo file. But again I'm interested in libraries, frameworks, etc.
Thanks so much!!
