Heya,
I needed to “analyze” the rhythm of some recordings I’ve made for a class, so I created a cheap tool for Windows XP to help me do that. It’s no science, you just click or hit a letter/number for every “beat” and you will get stats on the average beats per second you’re producing. I tried doing this with an online metronome at first, but to try to synchronize the metronome with the recording was just too much trouble, and also I could know I was off but not by how much, so that’s why I made this tool. Anyway, I’ll post the link here, if anyone has a need for this just feel free to download it, it should be virus free
