Return the title of the work in the audio file, if known.
This may be implemented by subclasses that support file tagging. This is not the same thing as the file name.

| virtual QString AudioFileReader::getMaker | ( | ) | const [inline, virtual] |
Return the "maker" of the work in the audio file, if known.
This could represent almost anything (band, composer, conductor, artist etc).

| virtual void AudioFileReader::getInterleavedFrames | ( | size_t | start, | |
| size_t | count, | |||
| SampleBlock & | frames | |||
| ) | const [pure 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.
Implemented in CodedAudioFileReader, and WavFileReader.
Referenced by WaveFileModel::getData(), getDeInterleavedFrames(), WaveFileModel::getSummaries(), and WaveFileModel::RangeCacheFillThread::run().
| void AudioFileReader::getDeInterleavedFrames | ( | size_t | start, | |
| size_t | count, | |||
| std::vector< SampleBlock > & | frames | |||
| ) | const [virtual] |
Return de-interleaved samples for count frames from index start.
Implemented in this class (it calls getInterleavedFrames and de-interleaves). The resulting vector will contain getChannelCount() sample blocks of count samples each (or fewer if end of file is reached).
