On Fremantle, the high-pass filter is enabled for the integrated microphone and disabled for headsets. I don't know why. Anyway, copying that setup shouldn't do much harm.

On Fremantle there's no "Earpiece Function", but there's "Earphone Function", which doesn't exist on Nemo. These probably refer to the same thing. There's also "Earphone" on Fremantle, which is apparently used for earpiece volume control. There's no obvious counterpart on Nemo, but "Mono DAC" seems to work pretty well as the earpiece volume control.

This is an incomplete representation, but still useful for writing or understanding configuration files. I'm not sure about the order of the elements and whether the volume elements are analog or digital, because it's hard to figure those things out just by experimenting (I guess the information would be available in the datasheet, but I haven't checked that).

Cut-off frequency for the high-pass filters that are applied to the data coming from the inputs (both ADC and the digital mic, even though there's "ADC" in the element name). I guess Item0 is for the left channel and Item1 is for the right channel.

On Fremantle, the high-pass filter is enabled for the integrated microphone and disabled for headsets. I don't know why. Anyway, copying that setup shouldn't do much harm.

  • microphone: enum = 0.0045xFs

On Fremantle there's no "Earpiece Function", but there's "Earphone Function", which doesn't exist on Nemo. These probably refer to the same thing. There's also "Earphone" on Fremantle, which is apparently used for earpiece volume control. There's no obvious counterpart on Nemo, but "Mono DAC" seems to work pretty well as the earpiece volume control.
