Is it mandatory to have an audio codec or DSP chip to use ESP ADF in a custom board ?

[migmel]

Hello guys,
I have a custom board which includes a MEMS INMP441 digital output microphone and a MAX98357 audio amplifier. Not any audio specific codec or DSP chip.
So, I wonder if it is still possible to develop ESP ADF applications with this custom board.
If not, why? If yes, what should I accomplish to do so?
Thank you

It is possible to develop ESP ADF (Espressif Audio Development Framework) applications with your custom board that has a MEMS INMP441 microphone and an MAX98357 audio amplifier. audio codec or DSP chip is not mandatory.
