Kick Detection

March 5, 2012 | 11:12 am

Hi, I’m trying to analyze a .aif audio file in real time so I can detect each hit of the kick drum and use that detection to generate visuals. At the moment I’m using the filterdesign object (bandpass) with cascade~ to try and center on the bass frequencies then sending that to bonk~ to try and detect the kicks, but I’m finding it very difficult to get good results. Does anybody know of a better method?

Thanks,

Kanisis

Try using Tristan Jehan’s analyzer~ external.

Thanks Marc, I’ll have a look into it. I’ve found a couple of objects and abstractions that detect beat but I want to know when the kick is and isn’t present. I’ll check out analyzer~ and see how I get on

I would also aim for Lpf combined with avg~ although you loose the "quick" attack, it should be enough to detect kicks… and you could also implement a counter and count the 4s…
