How to draw waveform of Android's music player? [closed]
问题 one of the default live wallpapers that came with my phone was a wallpaper that displayed the wave form of music playing in the background in real time. I was wondering how one could go about doing this. It seems I should somehow access the streaming data of the background music and compute the samples in real time, but I have no idea how to get the streaming data. I think I can display the wave form by following this tutorial http://codeidol.com/java/swing/Audio/Build-an-Audio-Waveform
