Yeah, that'll get Randy to help you out...

heh, well Randy has been ignoring my e-mails, so I assume that you have to be a customer to get support from him. Being a developer doesn't seem to get his attention. I don't expect him to help me out anyway, it was a last ditch effort.

It doesn't matter now anyway, I already have the code for beat detection working. I'm just trying to decide how to accociate the colour to the energy bands.
screaming:
Beat detection software has been around for a long time, and available in a nice neat package at least as far back as WinAmp 1.0.

I'm sure you guys have done your google searches; My 1 google search for "beat detection code" brought up 789,000 hits. But have you checked out WinAmp? It's dead simple to do as a visualization plugin, and I'm sure you will get a lot of helpful advice on their dev support boards.  Or how about the source of the old open source version?  One that note, have you looked at many of the other free, open source music players that do the same thing?

But wait, and maybe Howard will know more about this, but doesn't DirectX already include support for beat detection?

Out of curiosity, with all these other (free) resources at your disposal, why is Randy's code so important?  No doubt he has used these same exact resources for his version....

Yeah it has been around for a long time. So that's why I was perplexed as to why Randy wouldn't help us get the same effect in our plugins. Unless he's invented some new way of doing it, he hasn't accomplished anything that hasn't already been done. Incidently, the only matches I could find on Google for "beat-detection method based on the compression waveforms" are all patents!

Yes, I've done my own research on Google. Beat Detection has some complex maths involved. You can take a look at some of them here. I've chosen the "Frequency selected sound energy" method about halfway down the page and using an open source FFT library for .NET called Exocortex.DSP but the most popular one is fftw.

That would be news to me!

It's not that it was important, it was just strange to me that he didn't want to help out with example code. Like you say there is plenty of info on the Net. It just would have made it easier for us to implement the technology into our plugins. But alas, I have done it myself anyway...

Attached is a screenshot of my test application.
screaming:
good, I'm glad you were able to work through your problem! Good work!  :cheers:

Bump...

So it has been a while now Randy, you mentioned you wanted to release a completed version of beat detection, anything new?

Also, has anyone else done any beat detection for the ledwiz in the last 8 months?
