I might have tweaked a few months too little to understand the autoEQ properly, but to me it does not really behave.

I have a sh!tload of ripped tapes (around 600 complete sides end to end) and they are in very various quality and spectrum.

My preset is a very soft one and I only use NR, azimuth, stereo image, AGC, autoEQ, realbass, and advanced clipper only for the monobass, it does nothing else. Signal lands on a fabfilter limiter with 8x oversampling after that, so it doesn't matter if ST peaks way above 0dB in 32bit float behind the scenes.

My first action on the tapes is to normalize to 0 to have a consistent level to start with because the AGC cannot handle over 60dB of range between tapes. Then I have to tune the input/output/drive ranges so the AGC is average working in the middle of the meter, and no sudden jumps or compression.

I've tried several times to make a 9band autoEQ to take care of the typical problems on the tapes, but it often fails and wants to raise the volume way too high or not react at all. Some tapes have really crazy EQ on them already and I would think autoEQ would want to normalize those to the typical pink noise curve, so I got an idea, and that was to play a 10min pink noise through it and tweask all bands to do exactly nothing with only the relative dB as difference between bands and have maximum dB span on all of them, and it does work on the noise but not really on the music. It wants to raise the treble too high and kill too much bass.

This is how I approach it. How would you do?

I'd be happy if anyone wants to share an autoEQ setting that have a very broad range and doesn't mess up.

Hi! I'm also still learning how to set the AEQ/BEQ correctly. I listen exclusively to digital music, so my current AEQ probably won't help much. However, do you have a sample mix you can upload somewhere, of your most difficult song segments, we can use to work on?
