Digitalb> signal processing - Wikipedia, the free encyclopedia

In order tob> use an analogb> signal on a computer it must be digitized with an analogb> tob> digitalb> converter (ADC).
Since the goal of DSP is usually tob> measure or filter continuous real-world analogb> signals, the first step is usually tob> convert the signal from an analogb> tob> a digitalb> form, by using an analogb> tob> digitalb> converter.
Often, the required output signal is another analogb> output signal, which requires a digitalb> tob> analogb> converter.

Digitalb> audio workstation - Wikipedia, the free encyclopedia

A professional DAC performs the same function as a common sound card, but is generally an external and sometimes rackmounted unit which offers the advantage of far less noise (hum, static), higher recorded resolution, and better dynamic range, when compared with its consumer cousin.
Computer-based DAWs consist of three components: a computer, an ADC-DAC, and digitalb> audio editor software.
