Analysing spectral amplitudes as visually impaired?

Questions
1

Hi list,

I am wondering how visually impaired (blind) people would best be able to read and
trace the (time-varying) amplitude of spectral bins using supercollider.

Is there furthermore a UGen that tracks partials and is able to report the Nth
strongest partials by frequency and amplitude, comparable to [sigmund~]
in Pd? Perhaps PV_LocalMax is the best choice here?

Thanks for all ideas!
Peter

FluidSineFeature from the FluCoMa toolkit is the best partial tracker I know of.

You can poll the output to the post window or write it to a bus and .get from the bus in the language.
