There are a lot of single note sample packs that sound amazing but aren't well labeled: each sample with its note and octave. I was looking for a tool that identified the pitches in each sample of a collection, and couldn't find anything like that.
So, I made my own little program to do this. The algorithm used leaves room for improvement, but works quite well if the samples are clear enough. Also, if you like the results it gives, you can make the program to rename all the samples for you, adding the detected note and octave to its name.
This little program is available here: Joan Queralt / fatcat · GitLab
