Reason for this spectrogram behaviour
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!

it's just an artifact of the analysis process being done by the spectrogram;
theoretically it should just be a single vertical line at 440 hz, not a curve, but because of variables such as
input signal wave table size
input signal bit-depth
analysis window size,
analysis window shape,
sample rate
phase of the signal
analysis algorithm
you get artifacts
I see.
Thank you for the clarification!
