libmp3 visualizations?
Does anyone know how to get visualization type information out of libmp3 on the DC? I am trying to tie some graphical output up with music being played - not sure how to do it...

I'm not sure exactly what you mean with "visualization type information"... Beat detection? Spectrum analysis?

If beat detection and spectrum analysis is built in into libmp3 I do not know (probably not), but plotting the audio buffer that you send to the sound chip would give you the oscilloscope waveform, fourier transforming that buffer would give you a spectrum analysis and here are some tips for beat detection.
Have fun! :)

Yeah - I guess beat detection is what I'm after... thanks!quarn wrote:I'm not sure exactly what you mean with "visualization type information"... Beat detection? Spectrum analysis?
