I use Single Level Detector to read level in my program.
I find that the data from 1452 is 4 bytes which doesn't contain the sign bit, so I think it's not 8.24 format.
I have the following questions
1) What's the level mean, is it RMS level?
2) What's the format of the data, 32.0 or other?
3) How can I calculate the dB value from the 4 bytes?
4) If I get 0dB value from the 4 bytes, what's the final voltage output from DAC, assume that the DAC is ADAU1962.
