Part Number:TLV320AIC3268
When I use tlv320aic3268 to record voice from a mic and play it, I will found white noise. The white noise influences the quality of the voice.Its frequency distribution is from 0 to fs/2. So I also can hear high noise after using FIR filter.
Is the white noise produced in ADC when sampling and quantization?
How to configure 3268 in minidsp GDE can reduce the white noise?
What should I do to make the voice hear clearly?
Thank you!
