Hi Benoit,
Honestly I'm not the biggest fan of the AIC3204 EQ page. It's too hard to translate the results to register writes when you're not using an EVM.
I would instead use our TI Biquad Tool: https://www.ti.com/tool/COEFFICIENT-CALC
The software…
Hi Zhou,
The TI Biquad tool will allow you to determine the proper coefficients. https://www.ti.com/tool/COEFFICIENT-CALC Set your sample rate and then create your biquad frequency response that you want. Then click the "coefficient" button to see the…
Hi Sammy,
Unfortunately the bass and treble modes are exclusive, as they impact both Biquads 1 and 2. My recommendation is if you want more flexible control, use our TI Biquad tool to generate the coefficients and the load the values into the command…
Hi Zhou,
I investigated these errors and found that the PEQ part is bugged. Sadly because Purepath Studio has no active software support we cannot safely fix the bug.
My recommendation is to use the biquad blocks instead. You can use this biquad tool…
Hi,
I have an update here - you can download a TI biquad coefficient calculator tool here: https://www.ti.com/tool/COEFFICIENT-CALC
While it is not explicitly for this device, it can calculate coefficients for filters, and I was able to put in 24…
Hi Deveon,
Thanks for your reply.
I hope this COEFFICIENT CALC will help us during Board bring up / Audio debug.
I need an approximate Power consumption value for CODEC with 8ohm Spkr driving condition (SPKR VDD=5V) to do Power budget.
Could you…

Hi Neethu,
I'm not sure if that will work since the filter occurs prior to both the headphone and speaker outputs and you say the headphone output is fine.
But if you want to investigate you can use the TI Biquad tool: https://www.ti.com/tool/COEFFICIENT…
Hi Yazhi,
Using the test points on the EVM to connect an external I2S source is OK, however, the onboard controller (TAS1020B) is still operating and connected to the same signals. I'm guessing your I2S-mic module works as slave on I2S interface, similar…
Hi Terry,
TI has an online coefficient calculator to determine what values needed to program the programmable filter registers. Visit: https://www.ti.com/tool/COEFFICIENT-CALC and download the tool.
Plug in your values and click the Coeff button …
