TLV320AIC3256 - single-mic noise reduction algorithm

Hirotaka Matsumoto

Other Parts Discussed in Thread: TLV320AIC3256, LM1894

Hi all

Would you mind if we ask TLV320AIC3256?
TLV320AIC3256 has single-mic noise reduction algorithm and also miniDSP.
Our customer would like to use it instead of LM1894 noise reduction -10dB.

So, using TLV320AIC3256, we would like to know whether it is possible to achieve the same noise reduction -10dB or not.
If you have some comment, could you let us know it?

Kind regards,

Hi Hirotaka san,

The TLV320AIC3256 features two fully-programmable miniDSP cores that support application-specific algorithms in the record and/or playback path of the device. It supports the NoiseReduction TI Algorithm to attenuate the noise below a noise threshold (Range: 0dB to 20dB). It can be reduced from 0dB to 20dB.

Please take a look of the NoiseReduction Block Help Window for details:

I hope this helps you. If you still have questions or comments, please let me know.

Best regards,

Luis Fernando Rodríguez S.
