Understanding audio measurements: noise, SNR, and dynamic range

SNR is a ratio of level measurement and noise measurement (both typically as RMS level), expressed in dB. Signal level, measurement bandwidth, and weighting filter must be defined. Dynamic range is like SNR but noise is measured in the presence of small signal; results should be the same. Noise is one of the most important performance figures and typically compared to the signal level as SNR, Signal-to-Noise Ratio. In audio … Continue reading
