hi,
does someone know of an object that can make loudness correction based on Fletcher-Munson curves or something like that?
thanks ariane

I coded that for Alexandre T Porres while he was in Montréal this year. He's supposed to be publishing it, but I don't know where and when.

I like the sound of that (sic) because dB is too drastic and linear is wrong. Have you noticed how most television sets have a linear volume control? most computers too. These so-called "experts" need to be taught a lesson (about deciBels)
Metastudio 4 for Pure Data - coming soon! Metastudio 3 still available at http://sharktracks.co.uk/puredata

Linear compared to what ? Do you mean quadratic ?
I haven't measured the volume controls of my soundcard, but I don't get the impression that they are linear. They use some kind of "percentage" of whatever unspecified.
If I dust off my [SoundMixer] external (for accessing the OSS-Mixer) I could make a loopback test that plots a graph and then do some kind of curve-fitting. (that external was written in Ruby ; I'd rewrite it in C++)
most computers too. These so-called "experts" need to be taught a lesson (about deciBels)
But if they make "mistakes" like that, it looks like they are caring about those users that are "confused" by decibels. You know, user-friendly for real users, those users that are more real than the other ones.
