Audacity Forum

Cool, thank you so much for helping me with this! I'll look into the other views you suggested as well. Thanks again!!

Actually! I just wanted to clarify one more thing -- so for the example Autocorrelation spectrum in your post, the maximum correlation occurs every 0.01 seconds. So if the period is 0.01s, the key frequency is 100 Hz? What do the frequency values on the other peaks indicate? Thanks again!

Oh, awesome that makes so much more sense. Thank you for your help and detailed replies!

Hi! Thank you so much, that absolutely clears things up! So autocorrelation doesn't really give information about frequencies, more about the periodicity of a signal?

Hi! Thanks for the link! So what I'm getting is an autocorrelation just shows frequencies that reappear many times in a signal?

Hello! I'm using Audacity 2.4.1 for birdsong analysis and I'm hoping to use autocorrelation to get information on key frequencies of the call. I have a couple questions, listed below: 1. Does autocorrelation show the center frequency? If not, what is the difference? 2. What exactly does autocorrelat...
