hello
We have a machine with strong online tuning bass, but after burning the bass was very weak, and then I kept changing the Threshold value of DRC from -15DB to -6DB. I heard serious broken sound online, but after exporting the h file to the software engineer and integrating it, I upgraded to the machine and listened to the sound again, the bass effect was still the same, and I could not get out. The attachment is the h file and the source file I exported. Please check where the problem is. I suspect that the DRC written by the software engineer has a problem, please give me some advice, thank you!X40 20240522 —1.hX40 20240522 —1.rar
hi Han
i can't fully get your question.
when you flash the code, both having same problem? broken sound?
for you loose the drc threshold, if your speaker cannot suffer large voltage, the broken do have possibility to happen.
about how to calculate the gain, you can refer blow file.

Sorry, maybe the description is not very clear, the problem is: we want to make the bass of the speaker more, so we deliberately let the power amplifier distortion when debugging online, but the exported header file to the software engineer integration, and then to upgrade us found that the sound is not distorted, and the bass is suppressed, we want to know what is the cause?
hi Han
when you debug online, you used our evm?
does the hardware have any difference?
does the noise happen when debug online?
also, if the speaker ability is strong enough, even the output signal has distortion, the noise cannot be hear is also possible.
