I was wondering if you have used the "use_apll" feature to get a more accurate sampling clock as suggested in the IDF instructions. This is for the i2S configuration. When I set this to "true" the APLL clock message does show that the requested rate and real rate are virtually identical. However the...

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 s...

In spite of calibration the quality of the built in ADC in ESP32 is poor compared to other microcontrollers. Is there any effort to improve the performance?

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?

The board specs say max sampling rate is 96 kHz. However the ESP-ADF shows max rate of 48 kHz
