[gen] [sharing is barking]

I thought it would be fun to try and build a bark spectrum analyzer in gen~, as the foundation for some other stuff. I think I have the basic algorithm down, but I’m not 100% sure I have the math right. Any spectral analysis gurus out there able to take a look?

Thanks!

This is meant to go in a pfft~:

hey, i’m no guru at all, on the opposite was wondering what exactly is a bark analysis ; is it related to the bark scale https://en.wikipedia.org/wiki/Bark_scale ? so analyzing the energy of 25 bands of psychoacoustic interest dividing the frequency spectrum ?

Yes exactly — producing the Bark scale coefficients from a spectrum. Sorry, ‘bark analysis’ is probably not proper terminology.

I guess Mel scale could be interesting too. They seem to be fairly similar. Mainly I’m interested in a psychoacoustically based dimension reduction. 25 bands is a lot more manageable.

Hey Graham,

I’ve done a lot of work with bark scale spectrum analysis in gen~. I’m happy to pop the code up on GitHub, as I actually need a bit of help with certain parts of the project.

I’ll have a look at your code when I get home.

Chris.
