It is indeed possible to stream mono audio between 2 SOCs (nRF51 or nRF52 SoCs). I prefer the nRF52 series as it has the BTLE 2 Mbps mode which doubles the on air bandwidth, but mono audio works quite well even with BTLE 1 Mbps mode.

We have examples for Mono audio in the Smart Remote 3 reference design. However we do not have examples for stereo audio.

Our customers have however been able to achieve stereo streaming so this is indeed possible and this has been done using the nRF51 series.

One of the key challenges that you need to address will be Left and Right synchronization, which make stereo streaming a bit more complex than mono streaming. Unfortunately we do not have an out of the box solution for this.

If you need more support on your design, you can reach out on our one-on-one support forum called Nordicsemi Mypage.
