DSP: Volume-Variable Bass Peak/Shelf

Hi Folks!

Playing around with DAC-DSP using HifiBerryOS on RPI4.  Successfully played around with the DSP via the WebUI.  My goal is to run mono and use the right channel as a sub and the left channel as a high pass (100hz) full rangish driver ... I was able to achieve this.  However, I am building this into a smallish portable speaker and want to overdrive the bass BUT only at lower volume levels.  My goal is kind of like an automatic and variable "Loudness button" on older amps.  To be more specific: eg:

29Hz +10dB Q0.2  when gain is -35db

29Hz +8dB  Q0.2 when gain is -25dB

29Hz +6dB Q0.2  when gain is -15db

29Hz +1dB  Q0.2 when gain is -5dB

Question:  Is this possible with this DSP? If so, can it be done outside the windows program (CLI or WebUI is preferred).

Thanks!
