While the current architecture uses blocks, and so limits rt
requirements and possibilities, I see a potential use for an audio
system that provides sub-sample accuracy. As surround sound makes it's
way into society, a significant opportunity will present itself
regarding the psychoacoustic perception of location and movement of
individual sounds within the sound field. The ability to stream audio
as single samples and control the rate of playback with sub-sample
precision would open up some impressive opportunities. This is very
demanding. Jitter removal may be impossible since variations in the
sample playback rate would be an integral part of the signal. Such a
system would bring new meaning to the term "real time audio" and is so
far beyond the current state of the art that for now it is purely
academic. I think it is worth pursuing.
