Basically i'm gonna be working on an iOS music app which when a song is being played, it shows the fancy Equalizer meter, Something like this but with all the animation of bars going up and down:
After looking into this and not finding enough resource, I really want to carry this as a project perhaps making a web version using j query.
I'm not really asking for specific code, i just want to know how the animation works in general ?
Thanks a million !!!
Checkout the Cocoa Waveform Audio Player Control project. It's a cocoa audio player component which displays the waveform of the audio file.
Also, there is already a lot of questions on this topic:
iOS FFT Accerelate.framework draw spectrum during playback
Using the Apple FFT and Accelerate Framework
Animation would be pretty straight forward. It is just animating changes of the height of rectangles.
