9.1 Introduction

The benefits of converting from analogue audio to digital audio are:

• The quality of the digital audio system only depends on the conversion process, whereas the quality of an analogue audio system depends on the component parts of the system.
• Digital components tend to be easier and cheaper to produce than high-specification analogue components.
• Copying digital information is relatively easy and does not lead to a degradation of the signal.
• Digital storage tends to use less physical space than equivalent analogue forms.
• It is easier to transmit digital data.
• Information can be added to digital data so that errors can be corrected.
• Improved signal-to-noise ratios and dynamic ranges ...
