ESP32 Forum

Hello everyone.

I'm starting with ESP32 and I'm very lost.

I would like to record an audio file from an i2s microphone, encode it to OGG or vaw (pcm16), store it on an SD card and then play it back through a speaker, all as if it were a voice recorder.
The second phase would be to send the file via wifi or bluetooth with esp32.

I would be very grateful if someone could tell me which is the best hardware to start developing it.

Thank you very much for the answers.

Well, there are these:

Here is something with SPIFFS using the internal flash, only playback of PCMs though: https://github.com/MrBuddyCasino/ESP32_Soundboard
