Join Frank D. Cook for an in-depth discussion in this video A/D converters: How sound is converted to a digital signal, part of Pro Tools 12 Essential Training: 101.
- [Instructor] Earlier we covered converting a sound wave…into an electrical signal, using a microphone.…In order to record this signal on a computer,…for use with Pro Tools, the signal must be converted again…from a continuous electrical current…into discrete digital measurements.…There are two parts to this process,…taking measurements of the incoming electrical signal…at regular intervals, and converting…those measurements into binary numbers.…These tasks are handled by the Analog to Digital Converter…inside of your audio interface.…
Let's walk through both processes.…When an electrical signal enters the audio interface,…the Analog to Digital Converter begins taking measurements…of the incoming voltage at regular intervals.…Each measurement is called a sample.…The frequency of measurements is determined…by the sample rate that the converter is using.…If enough measurements are taken,…the system will be able to recreate the waveform…by plotting the sample values over time.…Think of this like plotting coordinates on a graph,…
