Reason for this spectrogram behaviour
Aug 20 2019 | 6:27 pm
Hey all,
why do the low-gain frequencies of this sine wave "jump" up and down?
I also tried using another analyzer (iZotope Insight)... it shows me the same bevahiour?
I have the feeling it's not some kind of error. Can somebody please explain?
Thank you very much!
