Re: Extremely precise sonogram ?

Here's a wavelet image of the same soundfile, shafqat.aif.

Wavelet analysis is pretty good, but indeed slow. Comparing the images, the FFT with reassignment and overlaps appears to offer better precision, espec. in the high frequencies.

I'm curious which FFT software allows for reassignment. Izotope RX, any others?
