This is a nice piece of code to change speed or pitch. It's in Audacity. However, pitch slide is not logarithmic, but it should be. Please change that, unless it's an Audacity problem. Also, please allow it to do more, like show the spectrograms it's using (not just the STFT, but the high-pass filtered in the fourier domain, and then written to a frame FIFO which does quadratic interpolating peak detection and track continuation version), or flip the spectrogram vertically in logarithmic scale (equivalent to Vertical Flip in Photosounder). What window size it uses?
