Having used a ton of different djing and music production software I can tell you that it's an open-ended problem because no software does it perfect. Some do it well, and most for example handle 4/4 dance music well due to the obvious kick drum. If you want it to be relatively accurate I suggest having a "tap tempo" button to override whatever it thinks is correct, not sure if that defeats the purpose but it might be a good sanity saver when the thing freaks out :)<div>

I am in two minds about beat detection. <div><br></div><div>On one hand, I was figuring that for a majority of music, if you divided the music into 8 beats, then found the strongest, you'd find the 1 or the 2 (which is good enough). Then it would play to any 4/4 type music but would also play for other patterns. (Would be disastrous in a Waltz. :))<div>
<br></div><div>On the other hand, I guess if we filter out some bands, perhaps we could actually detect the tumbadora open strikes (on 4 and the half right after). From my perception, this time period is fairly quiet with the rest of the instruments since this is the famous "Salsa pause" on 4 (and also the "cha cha cha" in cha cha).</div>
<div><br></div><div>In this case, the device may only respond to music that has this characteristic which would include things like Salsa, Cha Cha and so forth.</div><div><div></div><div><div><br></div><div><br>

Using multiband EQing you will get better results in your beat detection. IE notch filter around 200hz or so and then look for amplitude peaks to find the bass drum rhythm. You can find a chart of the eq bands related to each instrument, it will vary between styles and eras of music.<br>

A Mini-Maker Faire brings together families and individuals who celebrate Arts, Crafts, Engineering, Food, Music, Sustainability, and Science and those who embrace the Do-It-Yourself (DIY) spirit. At Maker Faire, the focus is on the process of making – not just the finished product.</p>
