T08 - Modern Sampling: It’s Not About the Sampling; It’s About the Reconstruction!

Jamie Angus, University of Salford - Salford, Greater Manchester, UK; JASA Consultancy - York, UK

Sampling, and sample rate conversion, are critical processes in digital audio. The analogue signal must be sampled, so that it can be quantized into a digital word. If these processes go wrong, the original signal will be irretrievably damaged!
1. Does sampling affect the audio?
2. Can we reconstruct audio after sampling?
3. Does sampling affect the timing, or distort the music?
4. Can modern sampling techniques improve things?
This tutorial will look at the modern theories of sampling, and explain, in a non-mathematical way, how these modern techniques can improve the sampling and reconstruction of audio.
Using audio examples, it will show that sampled audio, when properly reconstructed, preserves all of the original signal. Because it’s not the sampling but the reconstruction that matters!
