How can I get Image (.png) waveform from audiofile use EZAudio

I can show a waveform in AudioPlot Frame, but I could not get it in the form of pictures. EZAudio has such a method? And how can I use it?

Solution

  • EZAudio doesn't have such a method.
    You can try this solution from Tim (copied below for convenience).

    #import "QuartzCore/QuartzCore.h" after you added the framework to your project. Then do:

UIGraphicsBeginImageContext(yourView.frame.size);
[[yourView layer] renderInContext:UIGraphicsGetCurrentContext()];
UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

// The result is *screenshot
