Equal-loudness contours #13

Open alexkay opened 12 years ago

Moved from https://code.google.com/p/spek/issues/detail?id=18 :

Instead of using a linear scale for dB's like you (and almost every other program) do, I would be interested that you showed the colours according to the equal loudness curves.

Then, at least, you could actually say it is "acoustic".

Pre-determind lookup table might be helpful. http://blog.ericmarty.com/perceptually-uniform-pitch-loudness-scales-for-data-sonification pretty much sums it up at the end. Interesting issue, if solved might have some indirect applications in AI/deep learning via exports.
