SNR
Audio fidelity metric
SNR is an abbreviation for signal-to-noise ratio, a measure of how much useful information exists relative to background interference.
In audio and electronics, higher SNR means clearer sound or data.
Online, SNR describes the proportion of valuable content to irrelevant chatter: The SNR in that forum is terrible—mostly spam and arguments.
