Subclass of AudioFormatReader that reads samples from a single ARA audio source.
Plug-Ins typically use this from their rendering code, wrapped in a BufferingAudioReader to bridge between realtime rendering and non-realtime audio reading.

Use an ARAAudioSource to construct an audio source reader for the given audioSource.

| void juce::ARAAudioSourceReader::invalidate | ( | ) |
Invalidate the reader - the reader will call this internally if needed, but can also be invalidated from the outside (from message thread only!).
Definition at line 53 of file juce_ARAAudioReaders.cpp.
|
inline |
Returns true as long as the reader's underlying ARAAudioSource remains accessible and its sample content is not 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 |
