Audio, Distortion and Sound Analyzers

Audio analyzer - a test and measurement instrument used to objectively quantify the audio performance of electronic and electro-acoustical devices. Audio quality metrics cover a wide variety of parameters, including level, gain, noise, harmonic and intermodulation distortion, frequency response, relative phase of signals, interchannel crosstalk, and more.

Distortion analyzer - an electronic test instrument that measures the distortion produced in the circuit being tested.

Sound Analyzers – a harmonic analyzer for sound waves.
