Speak into a Wireless Microphone and output sound to Smartphone

Using Arduino Project Guidance
1

Hey Everybody,

I would like to speak into an electret microphone, similar to Sparkfun BOB-12758 (SparkFun Electret Microphone Breakout - BOB-12758 - SparkFun Electronics), and output the sound to a smartphone over Bluetooth.

I am not really sure if this is really an Arduino project. I thought about using the Blynk App, but I am not really sure that this is within the boundaries of the Blynk App...maybe making this more complicated than it needs to be.

I think that I need to obtain a microphone and connect it to a Bluetooth module with A2DP profile, OR just purchase a Bluetooth module with A2DP profile and integrated microphone.

Once paired with the smartphone, what app would I use to receive the voice from the Bluetooth wireless microphone.

I see many products online like this item from FiveBelow: bluetooth adapter wireless audio receiver w/ built-in mic | Five Below | let go & have fun

Any guidance is greatly appreciated.

TIA, --Neal

No, this is not an Arduino project. They are generally too slow and have too little memory for audio applications. Transmitting significant amounts of data to a smartphone turns out to be a significant challenge, too.

It isn't.

Use the readily available part designed for this purpose.

There are processors supported by Arduino IDE which have enough performance to support audio projects. Maybe the following will be helpful:

I did not test this myself but it looks like an active project.

Thank you everybody for your guidance.
