NRF51822 Audio Application & Compression

Hello,

I am working on an application that involves sampling audio data ~8KHz. I have a few questions

  1. The real time clock module has a maximum interrupt frequency of 32768/5 = 6554 Hz. Is there another mechanism to achieve a slightly greater interrupt frequency ~8KHz using the RTC? Or will I need to move to the Timer/Counter. Does nordic provide support for the Timer peripheral like it does for the RTC?

  2. Considering the BLE throughput limitation of the Iphone 5s = 4KB/s I will need to compress the audio data before transmission. Is nordic aware of any codec that works well on the Cortex M0 core of the NRF51822?
