Dear Nordic employee:
1、 what do I have?
I have a thingy52 develop kit（nrf52832）
2、what is my purpose?
the quality of thingy52 audio demo is not good（iphone7）
I want to increase the audio quality by thingy52
3、what is my question?
a、the PCM up rate is 8khz(8bit) but the PDMCLK is 1.032 MHz，according to the Specification，PCM should be 16125 Hz（16bit）,does the data has been compressed ? where control?
b、if I want to compress the data after converting to PCM，how can I do？ does the mcu have the compression algorithm inside already？
best regards！ thank you very much
