Dear Arnaud,

Thank you for your kind offer, but I won’t trouble you now for your implementation.

We are trying to follow the ISO standard which is based on 11 loudness categories, that is, 1 inaudible, and 10 suprathreshold. This seems crazy to me as ofc with 10 categories the midpoint is between categories. But maybe I’m missing something in the conversion to 0-50 categorical units.

Can I ask, is 4 the midpoint of audible categories in the 7-point scale that you used in you Matlab program?

Cheers

David

Hello :

I have a matlab progam somewhere that does that (7 loudness categories) with a friendly user interface! Tell me if it can be useful for you (you need Matlab).

best,

arnaud

Dear all,

Is anyone aware of software or scripts (on any platform) to perform Categorical Loudness Scaling?

Any tips appreciated

David
