| void CodedAudioFileReader::getInterleavedFrames | ( | size_t | start, | |

| ) | const [virtual] |
Return interleaved samples for count frames from index start.
The resulting sample block will contain count * getChannelCount() samples (or fewer if end of file is reached).
The subclass implementations of this function must be thread-safe -- that is, safe to call from multiple threads with different arguments on the same object at the same time.
