![]() ![]() In fact, so ubiquitous has it now become that, for many people, the word "digital" has become synonymous with "high quality". Signal processing functions can be implemented for a fraction of the cost, and in a fraction of the space required by analog circuitry, as well as providing functionality that simply couldn't be done in analog. Once again the reasons for the success of DSP are simple: stability, reliability, enhanced performance and programmability. Digital Signal Processing (DSP) technology has advanced to such an extent that almost any audio product, from a mobile phone to a professional mixing console, contains a DSP chip. Who would want to go back to scraping a needle along a vinyl groove now?Īnother advantage of digital audio signals is the ease with which they can be manipulated. Digital signals can be played back without degrading the carrier. Digital signals can be transmitted and copied without distortion. Since the introduction of the compact disc in the early 1980s, digital technology has become the standard for the recording and storage of high-fidelity audio.
