Add toggle_normalization on the Spectral Enhance (Fat Llama — GPU)

[oliverban]

Hello!

Fantastic project you have here, very cool. I do wonder though if there is a way of just gently lifting the audio to a secure level with the 🎛️ Spectral Enhance (Fat Llama — GPU) node. Right now, if autoscale is toggled on or off doesn't matter, my audio is always super-loud, would be great to set a max limit or something in LUFS or decibel, whichever is easiest!

I did see the original project has a "toggle_normalization", maybe that could be added to help as well?

Again, thanks for this! <3

Hi, sorry for the delay, I fixed the Fat Llama loudness issue by normalizing the internal PCM scale before processing (the upstream library reads integer PCM and was writing float output, which caused clipping when normalization was off). I also added a toggle_normalize option to the GPU node, and applied the same input‑scaling fix to the CPU node. Now it maintains the audio level from the input audio if you turn normalization on, if you turn it off it will have a higher volume output.
