beat detection

I know that beat detection in avs sucks and I thought I learned to live whith that but I just got a really great metal album (Symbolic by Death) and avs coldnt detect double bass drumm(it detects only one beat).
Does anyone have a good beat detection code for avs (using getosc/getspec)?

You might want to check the milkdrop forum for that. They used to have a huge thread on beat detection in there.

you can always make you avs react to getspec() data rather than using the in built detection. watch your spectrum analyser when you listen to music and you will see that certain bands coincide with beats or move to the baseline. you can also use it to increment a t value. i don't think that getosc can really be used for beat detection though
