-
-==========================================================================================
-
-0.0.1
-Initial release. 
-Components include: EZAudioFile, EZAudioPlot, EZAudioPlotGL, EZMicrophone, EZOutput, and EZRecorder. 
-Provided 6 example projects: CoreGraphicsWaveform, OpenGLWaveform, WaveformFromFile, PassThrough, Record, and PlayFile.
-
-0.0.2
-Fix for Cocoapod spec. Forgot to include files with .c extension.
-
-0.0.3 
-Changing EZAudioPlot and EZAudioPlotGL to scroll for the EZPlotTypeRolling instead of wiping the screen clean when hitting the end
-Allowed EZMicrophone EZOutput to have custom AudioStreamBasicDescription setters
-Fixed bug in EZAudioFile's getWaveformData function where it was not exiting after sending back cached waveform data (rereading from the audio file)
-Added stereo support for EZMicrophone, EZAudioFile, EZRecorder, and EZOutput
-Added more memory cleanup for EZAudioFile
-Added adjustable rolling length for EZAudioPlot and EZAudioPlotGL so those rolling graphs can now range from 128 to 8192 whereas before it was fixed at 1024
-Added adjustable resolution for waveform data coming from the EZAudioFile so output from the getWaveformDataWithCompletionBlock: function can literally be of any size. Try 128 for a low resolution waveform or 8192 for a much higher resolution waveform.
-Added quick fix for EZOutput to properly route stereo data coming from a circular buffer datasource. Next version (0.0.4) needs to add EZConverter to allow quick conversions between non-interleaved and interleaved formats.
-
-0.0.4
-Added ‘closeAudioFile’ to EZRecorder to properly dispose of internal audio file prior to trying to reload it using the EZAudioFile.
-Added new EZOutputDataSource method that provides pre-allocated AudioBufferList to fill instead of caller allocating and disposing on AudioBufferList. Much less errors.
-Added EZAudioPlayer for playback and visualization of local audio files (no network streaming yet).
-Merged bug fixes from community for EZAudio file. 
-
-0.0.5
-Added multiple destination recording formats to the EZRecorder (EZRecorderFileType)
