Frequency interpolation - spectrograms

Permanent link to this post Posted by Piotr Grochowski » Tue Sep 12, 2017 6:17 pm

Frequency in spectrograms is pixelated at their detail zoom. The only way to get a smoother frequency scale currently is zero-pad, but that only adds to the window size making it slower. Instead of nearest neighbor, how about bilinear or cosine (the one that you implemented on equalizer)?
