Hello Iwasaki-san,
Thank you for the additional information. I am assuming that the crackling noise is seen at the input of the CODEC.
For more information on calculating filter coefficients see the related posts below:

Hi,
PLL review comments:
Page 0, R4 : PLL_CLK is input to CODEC_CLKIN, but there is no source selected for for PLL_CLK [D3:D2]
PLL Settings are; P=1, R=1, J=4, D=0
NDAC=1,MDAC=8,NADC=1,MADC=48,DOSR=192,AOSR=64. Is below expected settings?

The coefficient calculator can be downloaded from ti.com, just search for COEFFICIENT-CALC or use the link from the PDF file:

Hi Harsh,
The issue is that 11.3 MHz is not a sufficient MCLK for 48kHz sampling frequency. With this MCLK, the sampling frequency that is supported would be a multiple of 44.1kHz, so if you want to record audio at that sample rate, you can use the…
Hello,
There is a dedicated high-pass filter option available and further filters can be designed using the Biquad filters. The attached tool aids in the design of these filters:

Zhang ping,
Please download the TI Biquad Coefficient calculator from the link below:
If you set the filter type to low pass, and Subtype to Butterworth 1. You can generate coefficients

Hi Lauren,
The TLV320AIC3206 contains several fixed function processing capabilities, including biquad filtering, which can be used for bass/mid/treble equalization.
There are biquads available both for the ADC and DAC stages and the configurations…
Dylan-san,
I cannot find some content on the section of development tool except COEFFICIENT-CALC under TAS6424 product page . Also I cannot find software of TAS6424Q1EVM page as well. Where can I submit the request? Kazuki Kuramochi
