SAMPLING RATE 96 kHz

Postby srini1948 » Fri Feb 15, 2019 10:57 pm

The specs for the LyraT board say max audio sampling rate is 96 kHz. However, the ESP-ADF only has a maximum setting of 48 kHz.
How to get 96 kHz?

Hi srini1948

Yes,the LyraT codec IC support 96kHz sampling rate, but the most of music rate is 48kHz. So we do the max is 48kHz. If can got the 96kHz music, i think we can test that.

I am using the board for a non-audio application where I need the 96 kHz sampling rate for ADC and DAC. Reading the codec reference manual I see that we need to set the device in "Double Speed" to get sampling rates between 50 kHz and 100 kHz.

Could you suggest some changes to the driver that will support this?

Thanks
