iOS Audio visualisation using AVPlayer

Question

I am trying to do an audio visualisation for a stream. The audio has to play in the background and currently I am playing it with an AVPlayer but I cannot get the metering from it. How can I get the metering and make the visualisation? Any suggestions?

Answer 1

• Here you have an example with waveforms: A cocoa audio player component which displays the waveform of the audio file

• Here you have a LED bar gauge and another example how can be used: ATTabandHoldAudioRecord

• Apple, also have SpeakHere example - the code includes a LevelView .. but this Apple sample code is anything but simple to implement ...
