Part Number: TLV320AIC3254EVM-K

I have an other question.

Now the AIC3254 works as well but I do not understand how can I configure the input in a way to use my microphone as an input. I tried to change some parameters in AIC3254 (Audio Input) but nothing works..

(My microphone is plugged in the J5 and my headset in J9.

Any advices would be interesting.

Moreover, I'm looking for ideas of GDE (Purepath) Audio chain which would be efficient to filter robust noise (from industry / BTP) in a way to recover the voice ?

Best regards,

Matthieu

  • Hi Matthieu,

    Are you able to get the on-board microphone to record using the preset configurations in the GUI?  This would confirm whether you're in an operational state before we dig deeper.

    Hi Colin,

    I am not able to get the on-board microphone using the preset configurations in the GUI. I do not know how to do that.

    You can see on this two screenshots my current configuration. I do not know what to go in a way to use this microphone.

    I hope you would be able to help me.

    Best regards,

    Hence I shall close this and use the other thread for support.
