Other Parts Discussed in Thread: TLV320AIC3262

Hello,

We are using the TLV320AIC3262 in our design, and we are trying to fine tune it. One of the two channels needs improved voice quality. We'd like to improve the filters to remove background noise. Is there something we can do in PurePath Studio to do this, or are there other ways/resources that would be helpful?

Thank you,

Jamaal

Hi, Jamaal,

Please take a look at the attached documents. They describe two PurePath Studio blocks that can be used in the context of noise cancellation:

Please let me know if you have more questions or comments.

Does you have any specific suggested settings for agc for a wearable voice recorder for best speech capture?

Hello, Jamaal,

Actually, it would depend of your signal requirements. Do you have the characteristics of your input signal (e. g. approx. amplitude range)? Also, do you have a specific target/gain?

Best regards,
