Hi
I have an A/D audio format (using A/D arduino nano converter, by connecting a microphone) and I send this format by HC-05 Bluetooth module to an android, and I’m trying to find a way to convert it and play it as a sound on my android, is there any way to do that.
Thanks
What is "A/D audio format"? I only know A/D converter and D/A converter.
which format?
I have a microphone connected to arduino nano via analog input (after amplifying), the arduino nano convert the audio to digital via A/D converter, then I send that via HC-05 Bluetooth module to an android, the question is there anyway to play this received digital format as a sound on the android ?
Thanks a lot
and again:
which (digial) format: mp3, m4a, wav, ogg, flac, ... ?
What have you tried so far?
I’m just converting the Mic audio analog signal to a digital via the A/D arduino nano converter, then send this digital signal to the android via HC-05 Bluetooth Module, it’s not mp3, or m4a or wav …
just I’m converting the analog audio Mic signal to digital with arduino nano A/D … it is a binary number between 0 and 1023 (8-bit A/D), sampling rate = 1/125us = 1/0.000125s = 8000hz.
I guess I have to convert the A/D output (8-bit data) to mp3 format (for example) with auduino before sending via HC-05 to android, but I have no idea how to do that.
Perhaps one of these discussions will help Hassan … https://www.google.com/search?q=arduino+a%2F+to+mp3+conversion&oq=arduino+a%2F+to+mp3+conversion&aqs=chrome..69i57.24970j0j7&sourceid=chrome&ie=UTF-8
One of the arduino forums might help you find a way to convert [

](https://forum.arduino.cc/) Have you tried that. What you want to do is an issue for the arduino experts.
I’ll see, thanks a lot
