TLV320AIC3254: White noise solution in TLV320AIC3254

Part Number: TLV320AIC3254

Hi.

Of the TLV320AIC3254 being tested


NR Process Flows -> Purepath studio In the example, I2S input is received and output via miniDSP.


However, I want to process MIC input.


I would like to ask for an example of removing noise when receiving and outputting MIC input to TI.

Or I would like to receive technical support related to this.

At present, I want to receive MIC input and remove white noise through miniDSP (I want to process only voice band).

Thank.

    Hi, Cho,

    Welcome to E2E, Thanks for your interest in our products!.

    The miniDSP of the 'AIC3254 is split in two sections, one for the ADC and one for the DAC. Each section can be programmed individually.  For the ADC, the input component you can select is the Decimator (DecXxIn) block and the output is the I2S_Out block. I would recommend you to look to the available example process flows that you can find in C:\Users\USER\Documents\Texas Instruments Inc\PurePath Studio (Portable Audio) MiniDSP 5.95\MyProcessFlows\Example Process Flows.

    Best Regards,
