Using a mp3 file to detect beat instead of sound stream

[tharinduc]

In the Sound section of the ofBook, they use sound stream when detecting the beat or calculating the rms. How to use the mp3 file loaded using ofSoundPlayer to calculate the beat or the rms in the way mentioned in the ofBook?

Hi, you need to use an addon for such. There is ofxSoundObjects which I co-wrote, that can be helpful. Check ofxaddons for other addons that probably can do what you want to.

The problem is that ofSoundPlayer uses a certain library to play files, which doesn't give access to the sound data, it just plays directly to the speakers. Hope this helps.
cheers

Thanks. I will check your addon. Im not a sound technology savvy guy. Im trying to implement some lighting effects using the arduino according to the song which is playing. Is there any easy way to contact you if I run into troubles? Thanks
