new to this whole DSP thing. Two related questions:
- Does there exist an algorithm or classifier that, when given two sound files, would be able to tell me if one is a pitch-shifted version of the other? There are algorithms that can tell you whether two images are resized versions of one another, I feel like this would be the audio equivalent.
- How would you write an algorithm that takes two recordings that are pitch-shifted versions of one another and spits out the amount of pitch shift. My naive guess would be to count zero-crossings in a fixed window for both recordings and compare the two counts, but I feel like that might lead to aliasing issues.
