Detailed Description

This class is used to expose any ReaderBase derived class as an AudioSource in JUCE.

This allows any reader to play audio through JUCE (our audio framework).

Constructor & Destructor Documentation

AudioReaderSource()

AudioReaderSource::AudioReaderSource	(	ReaderBase *	audio_reader,

The cache thread (for pre-roll checking)

Constructor that reads samples from a reader

Parameters

audio_reader	This reader provides constant samples from a ReaderBase derived class
starting_frame_number	This is the frame number to start reading samples from the reader.
