Sound tutorial
there are several different formats available for audio playback on the web. Two common and easy-to-create
file formats are wav and aiff files. Included within this tutorial is an
extensive example of these two formats and how compression can alter the way an
audio file will sound |

Digital filters digital filters, a digital filter uses a digital processor
to perform numerical calculations on sampled values of the signal. The processor
may be a general-purpose computer such as a PC, or a specialised DSP (Digital
Signal Processor) chip |

Timing errors and jitter
In a sampled (digital) system, samples have to be accurate in level and time.

at this instant” – and does subsequent maths on it, pdf file |
