Hello,

In order to receive 3 stereo I2S signals, I'm using the usbstreamer that is loaded with low LowSampleRate firmware.
I need to record the signals at a sampling rate of 64kHz and with 24-bit format.
I could not find the sampling rate and bit (64kHz, 24-bit)

How can I record the signals with the conditions(6 or 8 channels, 64kHz sampling rate, 24-bit)
For your information, the microphone that I used is knowles SPH0645LM4H-B.

2.
The recording data show the DC offset about 0.4 in case of the full scale of between -1 and +1.
Let me know that if there is the way to remove DC offset and instruction.

Unfortunately I'm afraid that we don't support such sample rate. Please check the user manual for more details on the supported sample rates. thanks!
