Basically the main issues are down to visualiser accuracy and dynamic range or normalisation going on.
Here’s a video showing a tone going from 100hz to 800hz with frequency bars starting at 250 and going up in 25hz increments each.

Testing the AudioVizBasicVolOrFreqs map and increasing frequency range I find no matter what settings I use with either a normal vocal sample or test sine tone it lacks accuracy in frequency response and how big the peaks grow.
A sound that should be quiet at certain frequencies is often made out a lot louder than it is and it’s just never very accurate or consistent if you repeat the same sound.
Another example is sometimes higher pitched sounds that have no bass still light up low bass frequencies when they shouldn’t?
This image shows a simple 500hz test tone and the frequencies to analyze. It lights up lots of bars that it shouldn’t but they’re also smaller or bigger than they should be no matter how quiet i make the audio. So you can see it’s not really showing volume level either. This is with fft set to maximum.
Perhaps accuracy is a limitation with the engine but surely it’s possible to at least have the levels show the volumes better. It seems to work better on some sounds but not others.
I really appreciate any help you can offer or improvements that can be made as i think this is a great project. Thanks.
