I want to take a sound file, and geometrically flip every frequency around, say,
A (440Hz). So A# becomes Ab, B becomes G, C becomes Gb... To basically flip the
frequency scale (f' = 440/f). It's a similar concept to
voice-inversion-scrambling. The only way I know how to approximate this effect
is by producing a spectrogram (with a logarithmic frequency axis), vertically
flipping the spectrogram, and resynthesizing it into sound with something like
ARSS or AudioPaint. Is there a better way? And if not, what program can I use to
generate high resolution spectrograms (large image files), so I can produce
better results with my current process?
