[Libvisual-devel] visual_audio_analyze

[Burkhard P. <pl...@ip...>]

Hi all,

I checked the libvisual CVS to estimate, what's necessary to port
lemuria to libvisual.

Lemuria has 2 variables, which trigger some changes of the animations:

quiet:         Set to 1 if silence began in these 512 samples, 0 else
beat_detected: Set to 1 if a beat was detected in these 512 samples, 0 else

I have my own routine for computing these values, but I borrowed it from
blursk some years ago and I think it's not the best possible beat detection.
In fact I have one song with lots of beats, but lemuria detects
not a single one of these :-)

 From what I see, they could go into the _VisAudio struct and could be
computed by visual_audio_analyze().

Are there any plans to detect such "audio events" in a generic way, or
should each plugin handle them itself?

If someones interested, I can post my beat detection stuff here.

Cheers

Burkhard
