Well I have Audacity and Goldwave, and I haven't found such a feature to apply these equations, so instead of being getting condescension for my questions I'd rather have a little assistance.

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?
