I'd like to know how the re and im variables in afftfilt work and what afftfilt is capable of. I'm new to frequency domain data and have some ideas in mind but not sure how to put them into practice. Can I for example implement filters or pitch correction/tracking? Or formant correction?

Thanks, Adam
