What is a converter and what is it used for?
To digitize audio signals in audio engineering, we first need a converter. In the case of digital converters, there is the A/D converter (A = analogue, D = digital), which generates digital signals (binary numbers) from an analogue oscillation (wave). These digital audio signals can now be saved, copied, modified, shaped into effects and, above all, converted back into analog vibrations. There is also the D/A converter. The analog vibrations can now be amplified again and converted into sound waves via a loudspeaker, headphones or other medium.
