View Full Version : Beat detection suggestion for AVS

I originally posted this in the AVS discussion - but it seems (having seen a couple of AVS suggestions in this forum) that it might be better off here ... all of which is really me saying "sorry for the cross-post, but I think I've got the right forum this time :)"

One of these I'm certain you'll have heard before, the other maybe not :

[list=1]
Would it be possible to have the beat detection algorithm automatically (or on demand) save detected BPM rates to a file? Note sure quite how useful this would be unless a stream of BPM data were saved (as opposed to a single value). On re-loading the values probably shouldn't be used literally but rather to "hint" to the algorithm the direction it should take at regular intervals? I was thinking of something along the lines of the Equalizer's auto-load preset functionality...
I've got quite a few songs where the beat detection never *quite* gets it right... Would it be possible to add a "manual" beat detection mode whereby the user tapping a key on the keyboard or clicking away on the mouse in time to the music would either set the BPM rate or give the algorithm a really strong "hint" about the kind of speed it should be looking at. Combined with the auto-load function above this could be quite powerful.
[/list=1]

A suggestion was made in the forum to encode the "manual" beat detection as an APE in AVS, but I think enhancing the algorithm inside AVS is a better way as it avoids having to add the APE to any presets one wishes to use manual beat detection in.

Finally, thanks to NullSoft and all the AVS coders for such an awesome piece of kit and a pile of fantastic presets (oh, BTW, love the new fullscreen overlay mode - even my rather underpowered laptop can now run fullscreen with decent fps!)

Cheers,

Dave.
