Esp32 bluetooth + 3.5mm connections

[ked769]

Hey guys, software nerd here, have a project im thinking about. Way out of my league and know nothing about hardware but i know a hardware nerd so do see if we can acheive this.

I have a multi fx pedal for my guitar with a 3.5mm headphone output jack(i hope thats the right diameter), where you would plug in wired headphones. But i really cant be stuck glued to my desk whenever i need good quality sound and my amplifier aint the best.

I was thinking, can the ESP32 Dev module communicate with this headphone jack, receive the signal, and then send it wirelessly over bluetooth to my earphones? I have jlab earphones which are sort of similar in build to galaxy buds, if thats relevant.

This can take as long as needed and i really dont care how hard it might be, whats the best way to go about a low latency solution to do this?

TLDR: headphone output ----> ESP32 Dev --(bluetooth)--> bluetooth headphones
Plausible?

I think you can buy such an adaptor. ... with esp32 you will face many challenges deciding sampling, or even realtime sampling technique (were you lose quality, enters "Mike") and then the bluetooth part transmitting audio is also overwhelming.

Is there a different microprocessor or pre existing device for me to use for this?

If you just want to stream audio via bluetooth I don't see why you need a microcontroller at all. Why not just use such a device?

How would i ensure it connects to the right device when in tx?
