Convolver introduces huge volume shift

EasyEffects Version

7.0.6

What package are you using?

Flatpak (Flathub)

Distribution

Fedora 38

Describe the bug

Hey as figuring out the best way to try out tube sound i actually came across your mentioned impulse responses, after converting them to stereo i was able to load them into the easyeffects convolver plugin but the volume shifted quite a bit, i had to lower it around -16db, it actually kinda depends on the impulse response im using

is this volume shift intended?

Expected Behavior

output volume stays the same as input volume

actually the -16db are just so much because i disabled the automatic amplifier thingy in the convolver plugin, it was reducing volume to some degree but it wasnt enough on its own, it was still clipping with the input signal having -6 to -10db headroom

7.0.6 is quite old, you probably want to update to 7.1.0 with flatpak update

is this volume shift intended?

Not intended as in "we intentionally put it there". As far as I know shift in the signal level is inherent to the convolution process. The amount depends on the impulse being used indeed. The autogain feature in our convolver tries to do some compensation but it is not perfect and it does not work well on some impulse files.

I happens also to some autoeq downloaded impulse responses without autogain. The problem is that with autogain you could still clip.

There was a normalization related thread at: https://github.com/jaakkopasanen/AutoEq/issues/388

I think that we could better notify the clip notification in the meter so (>0.0dB) so that we could use autogain with eventually the pre-amp compensation.
