Convert a .wav file to .mp3 with the dfx filter added directly

Is there a way to convert a .wav file to .mp3 with the dfx filter added directly?
In the past it was possible using a program called MusicMatch + DFX, my question is if there is a similar option nowadays.
thanks

We don’t have this built into FxSound unfortunately. It’s not something we get many requests for, so I’m not sure that it’s something we’ll add.
