I am bit confused in trying to use an AudioFormatReader in that this function

` void read (AudioSampleBuffer* buffer,
                   int startSampleInDestBuffer,
                   int numSamples,
                   int64 readerStartSample,
                   bool useReaderLeftChan,
                   bool useReaderRightChan);
`

and uses AudioSampleBuffer

which is typedef’d as a float version of AudioBuffer.

which means makes it tricky to use in the double version of the process function in an AudioProcessor.

I must be missing something.
