Spectral display performance in Waveform view.

Hi, dear colleagues.


I noticed that when editing audio in Waveform view the spectrogram draw (render) performance is slower while working with longer files. For example when editing an interview or a podcast I delete a section, than drag the view forward using middle click, and the time needed for the view to refresh is in positive correlation to audio duration.

Also, it's getting slower the more edits are done, so by the end of editing a 50-minute episode the view draw is falling down significantly, and if I just close and re-open the file - it is fast again.


This is very strange, especially on a very fast NVMe with around 4000MB/s seq. read speed.


Also, if you open the Task Manager on the CPU performance tab and drag the audio in Audition using middle click back-and-forth - only one Physical core is being loaded, around 25%, and the GPU isn't used at all.


I can confirm this on four different processors, and on 2 versions of Audition, so this is just as it works and not a bug or something.


Now the question: does anybody know why this is happening or how to improve it?
