How can I lowpass sounds in SoLoud?

[Ar-Ess]

Straight forward. I need to generate an underwater effect with SoLoud.

I can't find any filter for that... A direct LowPass Filter. Is there any extra or way to do that in the library?

(if the only way is doing it manually, how do I acquire the float array of the audio? Is there any place that explains how to do it?)

Thanks!

the BiquadResonantFilter can do what you want. https://solhsa.com/soloud/biquadfilter.html
