enhancement: effects reactive to speaker volume

[marcelohdez]

Hello, easyeffects is a great program which I use to make my speakers not sound completely horrible compared to my Macbook Air on my Framework 13.

However, Macbooks and other small speakers (AirPods, Pixel Buds Pro) use adaptive EQ's where they boost bass and treble on lower volumes to encourage lower volume listening and a fuller sound, due to how we hear sound, following the Fletcher–Munson curves.

Example: Macbook Air 2024 frequency response graph on RTINGS, here the frequencies below about 800hz stay the same volume as the speakers get louder, however the frequencies above that are all boosted.

I was wondering if there'd be any way a similar effect could be emulated with EasyEffects, even if it is just on the EQ plugin, like "from" and "to" sections which could be interpolated as speaker volume goes from 0% to 100%

The loudness plugin available on EasyEffects process audio based on the Loudness curves. You can even select different ones. But may just using the autogain is enough. IT will depend on your hardware and your needs.

Without having access to the code being used on Mac it is hard to say if it is possible to completely replicate its behavior. But with the plugins already available on EasyEffects it should be possible to get close to it.
