It is possible to measure the full 20 Hz–20 kHz range using a sweep (though distortion for a fundamental above 10 kHz is inaudible). Measurements for calculating the THD are made at the output of a device under specified conditions. The THD is usually expressed in percent or in dB relative to the fundamental as distortion attenuation.
Vinyl microgroove phonograph records typically yield 55-65 dB, though the first play of the higher-fidelity outer rings can achieve a dynamic range of 70 dB. [25] German magnetic tape in 1941 was reported to have had a dynamic range of 60 dB, [26] though modern-day restoration experts of such tapes note 45-50 dB as the observed dynamic range. [27]
Spurious-free dynamic range (SFDR) is the strength ratio of the fundamental signal to the strongest spurious signal in the output.It is also defined as a measure used to specify analog-to-digital and digital-to-analog converters (ADCs and DACs, respectively) and radio receivers.
Most modern quality amplifiers have >110 dB dynamic range, [6] which approaches that of the human ear, usually taken as around 130 dB. See Programme levels. Phase distortion, Group delay, and Phase delay A perfect audio component will maintain the phase coherency of a signal over the full range of frequencies. Phase distortion can be extremely ...

But if that’s not possible, I’m not going to apologize for my full-fat recipes.” This, Albright explains, is “the enactment of a value.” “There’s a tension between health and ...
Clipping of a digital waveform. The red lines indicate full scale, and the waveform is shown before and after hard clipping (grey and black outlines respectively). Decibels relative to full scale (dBFS or dB FS) is a unit of measurement for amplitude levels in digital systems, such as pulse-code modulation (PCM), which have a defined maximum ...
