mids and reverb broken

when using a lot of reverb, the pubbed track will have way more mids than the draft. it's twice ive noticed this now

I'd suggest to add a link to an example.

even with added eq

Hey, since remix is disabled and I'm not a dev, I can't look at the draft. But I recorded a section of it in Audacity and the waveform shows a lot of DC offset, around -20 dB. I don't know if this is related to your mids problem, especially since the frequency spectrum analysis doesn't seem off, everything looks typical and balanced. I used to have the DC offset problem when monitoring audio signals from cables with the solo/cue function. Did you leave any soloed cable in your draft?

nope. It's an audible difference between the draft and the pub. The pub is more high pitched and mid heavy. Trust me i'm not a prodigy of sound but I can hear the difference. Just wondering what the best course of action is.

Its bizarre tbh

isn't dc offset just infrasonic frequencies offsetting your waveform?

yeah wouldn't a highpass fix that?

DC Offset is constant. It has no frequency.

I enjoy the project epsilon ( epilepsy ) guy always coming up with his brilliant ideas that never make any sense. Wannabe professor :)

DC is 0 Hz. A highpass should fix that as @nechurot suggested.

I gave both versions a listen and they sound perfectly equal on my equipment.
The aforementioned DC-offset might be the key here. Maybe your Hardware/driver/decoder makes a difference when handling such an offset.
You can see that offset in the visualization in the website player (leftmost bar has a high level) and on the left end of your spectrum in your track.
Maybe you can find out which constellation is causing this effect and get rid of it. Another approach is to remove that DC-Offset with a high pass filter (very steep and lowest possible frequency) as @nechurot suggested.

looks like this

I'll keep this issue open to have an example for that DC-issue.
