ACB reader, Matt, suggested I try the time correction technique in the last post in a different order. Previously I had dropped the pitch two octaves and then brought it back up two with the time correction enabled. This time I did the opposite, starting by increasing the pitch then lowering it to its original position. It definitely has a different sound. I think it’s much closer to the original than the previous example, but still an interesting way to manipulate the clip.
Time Correction Overload 2
Today during my audio production class I was demonstrating to my students how time correction impacts digital audio when pitch shifting more than a few semitones. To illustrate this I pitched down a chunk of music an octave with the time correction on in Pro Tools. The degradation was clear, but it occurred to me that it would be even more obvious if I shifted it back up to the original pitch with time correction enabled again. 
Here’s an excerpt from a piece of music that I created using the noise that the pedal on my suitcase Rhodes makes if you step on it the right way. The sound is processed using some of my usual techniques. I also programmed a beat of the top and laid down some reversed Rhodes and well as a simple chord progression. This probably won’t get developed much further, but perhaps I’ll use it as a segue piece of some sort. 
I’m calling this one minute and twenty four second experiment Six Machines, simply because after applying the first round of processing and looping the phrase a vague melody in six / eight time is discernible. The first round of involved applying destructive processing in 
What you hear in this clip is all of the processed noise extracted from
