Subclass of AudioFormatReader that reads samples from a group of playback regions.
Plug-Ins typically use this to draw the output of a playback region in their UI.
In order to read from playback regions, the reader requires an audio processor that acts as ARA playback renderer. Configuring the audio processor for real-time operation results in the reader being real-time capable too, unlike most other AudioFormatReaders. The reader instance will take care of adding all regions being read to the renderer and invoke its processBlock function in order to read the region samples.

Create an ARAPlaybackRegionReader instance to read the given playbackRegion
, using the sample rate and channel count of the underlying ARAAudioSource.

void juce::ARAPlaybackRegionReader::invalidate | ( | ) |
Invalidate the reader - this should be called if the sample content of any of the reader's ARAPlaybackRegions changes.

inline |
Returns true as long as any of the reader's underlying playback region's haven't changed.

Subclasses must implement this method to perform the low-level read operation.
Callers should use read() instead of calling this directly.
destChannels | the array of destination buffers to fill. Some of these pointers may be null |
numDestChannels | the number of items in the destChannels array. This value is guaranteed not to be greater than the number of channels that this reader object contains |
startOffsetInDestBuffer | the number of samples from the start of the dest data at which to begin writing |
startSampleInFile | the number of samples into the source data at which to begin reading. This value is guaranteed to be >= 0. |
numSamples | the number of samples to read |
