Send audio signals by Bluetooth - Choosing the right arduino

Hi there,

I'm quite new in the using of arduino, and I know that the project that I want to do isn't an easy one. Although, I really want to do it, since the headphones I'm using doesn't accept audio input via analog and only uses Bluetooth.

If you read the title, I would start on what I would need to do such project. I already know that I would need a Bluetooth shield, but I wonder if there is an arduino that accepts audio input, or if I should use an audio shield. If the shield is the choice, I would like to know which arduino will be able to put those two shields together.

Yes, I've tried to search on Google, but the result are confusing for a beginner like me.

Have a nice day!
