the future of digital audio

  it must require: very high speed sampling rates. ultraSampling So high we'll use >100x data rates and storage. this is to have ultra-low latency for tracking and live work. most likely this would not run on a standard computer-based system very well due to driver latency. standalone embedded systems would provide best performance. the systems require end-to-end very high sample rates, from ADC to DAC, in order to achieve very low latencies far below the ability to hear it. simple integral upsampling provides backward compatibility of media assets. current practice zero-latency analog monitoring will remain essential, allowing favored outboard analog inserts, but ultrasampling will add near-analog latency, allowing favored processing in digital. sampling rates required are one to two orders of magnitude greater than present to even begin to approach near-analog latencies, more specifically, below perceptual threshold. many claim 7-10ms being below threshold
