It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

For those of you trying to balance audio fidelity with average output power, here’s a new concept for you. Many systems, especially those in the home theater / mini-micro combo market, deliberately ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

National Semiconductor Corporation has introduced two LME™ families of high-fidelity audio operational amplifiers (op amps) that practically eliminate distortion, with total harmonic distortion plus ...

I googled a bit, but couldn't find any good apps that help assist in the testing of an audio device (like an MP3 player). I would like to test the THD and the SNR of the device. Are there any good ...

The author is technical publications manager and a senior technical writer at Audio Precision in Beaverton, Ore. When reduced to its basics, the process of audio test and measurement is concerned with ...
