Analog to digital
An audio signal is an analog
The electrical waves must be
converted to digital information for
Digital recording is accomplished with
an analog-to-digital converter (ADC)!
The ADC captures a snapshot of the
electric voltage on an audio line and
represents it as a digital number!
Capturing the voltage thousands of
times per second creates a good
approximation of the original audio
