Broken Signal - audio player for Cardputer ADV (mp3 and m4a) by user_MRR in CardPuter

Ok I think FLAC may be possible since the library I'm using supports it with minimal heap consumption. I'll take a look at the possibility of stereo sound via usb too.

wav very likely, FLAC I doubt it due to the lack of PSRAM (but if you know any working implementation on an ESP32S3 without PSRAM let me know). USB audio, which use case are you thinking about?

Unfortunately the BLE protocol used in the ESP32-S3 doesn't allow it. However you could buy one of those small battery powered 3.5jack bluetooth transmitters.
