Other Parts Discussed in Thread: TLV320AIC3253

Dear,

We want to find a Codec IC having these function.

1. support Dual microphone

2. Echo cancellation, noise restraint, EQ modulation, wind noise restrain

3. 2 IIS interface; 16/24bit stereo ADC/DAC

Could you give some advice? Thanks

Hi, Sundy,

We have several codecs which supports the dual microphone and audio interface requirements, however, we don't have a codec with an embedded processor capable of performing effective echo cancellation algorithms. If the option to handle the advanced algorithms an external DSP is possible, I can help you with the best codec recommendation.

Hi Diego,

TLV320AIC3253 embedded a miniDSP. Does it can fullfill the ctm requirement? Thanks!

Hi, Sundy,

As mentioned before, the processors in our codecs (including the MiniDSP) don't have enough processing capabilities to perform effective echo cancelling algorithms. Advanced processing should be implemented in an external DSP.
