Usage
Checkout the demo app for an example.
Customizable attributes:
/// The upper bound of the frequency range the audio plot will process. Default: 10000Hz
@property (nonatomic) float maxFrequency;
/// The lower bound of the frequency range the audio plot will process. Default: 1200Hz
@property (nonatomic) float minFrequency;
/// The number of bins in the audio plot. Default: 30
@property (nonatomic) NSUInteger numOfBins;
/// The padding of the bins in percent. Default: 0.1
@property (nonatomic) CGFloat padding;
/// The gain applied to the heights of bins. Default: 10
@property (nonatomic) CGFloat gain;
/// A float that specifies the vertical gravitational acceleration applied to bins in the audio plot. Default: 10 pixel/s^2
@property (nonatomic) float gravity;
/// The color of bins in the audio plot
@property (strong,nonatomic) UIColor *color;
/// An array of color objects defining the color of each bin in the audio plot. If not set, the color attribute will be used instead. Currently not supported by Buffer type.
@property (strong,nonatomic) NSArray *colors;Dependencies
- ZLHistogramAudioPlot is a subclass of
EZAudioPlot. It requires EZAudio. - It also requires Accelerate framework for hardware acceleration.
Compatibilty
ZLHistogramAudioPlot uses the following interface provided by EZAudio to get audio data:
- (void)updateBuffer:(float *)buffer withBufferSize:(UInt32)bufferSize;It can be easily modified to work with Audio Unit and Core Audio.
Requirements
- iOS 6 or higher.
- Automatic Reference Counting (ARC).
