is (would) it (be) possible to use ffmpeg audio filters in aimp?

[crysis_78]

Hi, I would like to know if a feature like this would be possible (or if it is already possible) in aimp. So you could use audio filters in realtime, like

Code: [Select]

loudnorm or

Code: [Select]

dynaudnorm like you can for example in mpv (video player)

Thanks for any help

loudnorm

AIMP has it own volume normalization filters, like peak-based normalization and replay gain

I know, I tried them but I dont understand what they do, or how to set the correct settings.

What exactly hard to understand here?

How does it work? does it work with LUFS (human preceived loudness) or normal dB/RMS. Audio normalization is a complex topic and the only thing you can adjust is one dB value (from what I have seen)
I have tried dynaudnorm, loudnorm 2pass and ReplayGain and nothing gives a good enough result.

Maybe you know about any other solution that could work?

Yes, the replay gain option does it.

normal dB/RMS

It is peak-based normalization.

Maybe you know about any other solution that could work?

What is your goal? What settings you've tried in AIMP?

I try to normalize audio/music (big playlist with many genres, from Nu-Metal to Classic/Folk) I have already tried loudnorm 2pass and dynaudnorm. Dynaudnorm is very good but there are still big differences between tracks like 6-8dB, as it does not work with LUFS (human perceived loudness) but with dB/RMS, so its not possible to balance a (high compressed) Heavy Metal track to a (low compressed) Country/Folk song.
Loudnorm in 2pass can achieve that but I have no (real) experience using it. It also has (adds) more treble (sounds brighter) as it weights this frequency more (K-weighting filter) so it's kinda also an "Equalizer" which I don't know how to feel about.

I have tried the both options that are available, ReplayGain just reduced the volume. And the peak one, its hard to say which effect it had.

I made my own script for that
