Audio Transmission over BLE

Question

I am going to work on a project, and was wondering possible ways to transmit audio (captured from mic), to a android device or so over Wireless Bluetooth Low Energy (BLE), what could be best possible ways to explore to implement and do this, aim is to achive that with Arduino NANO 33 BLE Sense(given form factor and ease of dev), but am also trying to figure out on how it's done for other similar MCUs if not this, so it would be great if anyone has worked or knows could share about how can I start about achieving this goal of Audio Transmission over BLE...

Thanks

As you probably know the Arduino Nano 33 BLE board uses the nRF52840 chipset. So I suggest you look on the Nordic Semiconductor's website to see whether it's possible with this chipset, as it's theoretically possible knowing that Nordic offer the functionality. I also think they are probably better placed at answering this question (can ask on their forum).
