Beat Detection Using JavaScript and the Web Audio API

What is the corner frequency of the low-pass filter? It is kind of pointless to use a filter without specifying its corner frequency.<p>Also, peak detection can be improved a lot by searching for local maxima of the level instead of taking a threshold of the amplitude.<p>As a scientist of acoustics, I find this approach frustratingly naive. Still, nice write-up!

Nice write-up. Thanks!<p>I wonder if the algorithm can adapt to recordings where the tempo isn&#x27;t quite constant.<p>Amusingly, I first read &quot;beat&quot; as a verb in your title, and was expecting something cloak-and-dagger.

Thanks for this write up, I really enjoyed it. +1 to the suggestion to adjust the threshold based on the average volume in a section, maybe using a sliding window.

Nice! I&#x27;m trying to convince my brother to use similar techniques in his game to allow the environment to respond to music played by the user.

A really nice article, but not really an advanced algorithm. What would be really interesting is an explanation of something like Ableton warp engine, which can automatically detect and warp to the grid tracks with fluid tempo.

Wow, in my half-awake state I initially read that as &#x27;BEAR detection using JavaScript and the Web Audio API&quot;. Unfortunately the article did not live up to the promise.<p>j&#x2F;k, very cool :)
