Analog to digital conversion

Analog to digital conversion: Digital Audio Foundations
Analog to digital conversion: Digital Audio Foundations

Matt outlines how sampling works to convert analog audio to digital. The analog-to-digital converter takes measurments of the analog signal at a specific sampling rate such as 44.1kHz. Before the samples are taken, the audio goes through an anti-aliasing filter to remove any frequencies above the Nyquist limit, or half the sampling rate, which could potentially cause aliasing distortion. Then each sample is quantized, or rounded off, to a number whose precision is determined by the bit depth, such as 24 bits per sample.
