Interleaved Files.m4v

CD audio files, stereo mp3s, and others, like Dolby Digital files, are actually a single mono file where the data making up the left and right (or left, center, right, the surrounds, and the LFE) are mixed together as a continuous block of data. This is what's known as an interleaved file.

Since the raw bit rate is considerably higher than the audio bit rate, meaning that digital devices can read data faster than they play audio, they are continuously filling RAM buffers so that left and right channels of a CD or the six surround stems of a Dolby Digital movie play with no noticeable breaks.

This is especially helpful with Dolby Digital, since the audio bit stream is actually printed in the spaces between the sprocket holes, so that the raw data stream has gaps that occur regularly.

However, interleaved files do create latency, because the interleaved block must be read before the packets of data can be decoded and routed to the various outputs.
