I know I am missing this weeks macro-post, but here is something to tide you over

I sat down with Adam for 10 mins yesterday, and we looked at the code example I had made for modifying an audio loop.

It turns out that the code was making a mono edit of the stereo signal. This has now been rectified, and I just need to modify the normalisation function to work with the stereo signal. That should not take too long.

Finally, I will look at modifying the program to change the normalisation offset level, the incured % values to THD per non-linear device. Once this is up and running, I will make a version for each nonlinear equation in the Hawksford & Woon-Seng Gan paper 'Perceptually-Motivated Objective Grading of Nonlinear Processing in Virtual-Bass Systems.

I am also on the hunt for more non-linear equations that describe behaviors of nonlinear devices, particularly loudspeakers and amplifiers. One of the problems with the Hawksford paper normalised models is the normalized parts rely on the exponential function a lot, and are therefor not easy to attenuate the curves of.

More to come shortly.

This week I am also going to look more into literature relating to perceptual models for amounts of distortion and loudness. I am also going to start thinking more about the bits of human hearing that come into effect when thinking about loudness.

I will start by thinking loud, with the Acoustic Reflex.
