Hi. I have a few question regarding the headset codecs with DSP and amplifier. I have no experience with SigmaDSP.
1) Can I take PCM or I2C audio directy from a WT32i bluetooth module? (The codec has to work as a I2C master.)
2) Can I run the bluetooth signal through a equalizer, and a audio line-in signal from ADC through a separate equalizer, then mix the signals 50/50 before sending them to volume control and the DAC?
3) Can I control a peaking filter (High-Q) filter frequenzy via I2C?
Best Regards Kristian
