Further exploration into the A=432Hz phenomenon has yielded an unexpected creative outlet...
A=440 music pitched 8 Hz lower than it is recorded is purported to have some of the same therapeutic value as music performed and recorded at A=432 Hz. Re-pitching some of my favourite music, using Audacity -
http://audacity.sourceforge.net/ - has resulted in a collection of soothing audio that helps me refresh between mastering sessions, relax after a stressful day, or tune out mental "noise" when in agitated frame of mind.
The problem: re-pitched music tends to contain odd digital "artifacts" - bits of strange audio phenomena that were not present in the original recording.
My solution: over time, I've come to regard remastered 432Hz audio files as a type of technical artform, similar to sampled/looped productions, beat slicing, or "low-fi" remixes of existing audio content. Re-mastered 432Hz audio is never going to sound absolutely like the original, no matter how good the re-pitching software becomes, so why not make it a cultivated taste - purposely altered to an inexact representation of the original?
One gets an interesting bit of altered audio, plus many of the physical/psychological benefits of music performed and recorded at A=432 Hz. In our new world of audio possibilities, this is one more direction a digital audio artist may choose to pursue.
