A Band-pass filter showing the centre frequency(Fc), the lower(F1) and upper(F2) cut off frequencies and the bandwidth. The upper and lower cut-off frequencies are defined as the point where the amplitude falls to 3 dB below the peak amplitude. The bandwidth is the distance between the upper and lower cut-off frequencies, and is the range of ...
The P3b is a positive-going amplitude (usually relative to a reference behind the ear or the average of two such references) peaking at around 300 ms, though the peak will vary in latency (delay between stimulus and response) from 250 to 500 ms or later depending upon the task [2] and on the individual subject response.

Peak normalization adjusts the recording based on the highest signal level present in the recording. Loudness normalization adjusts the recording based on perceived loudness . Normalization differs from dynamic range compression , which applies varying levels of gain over a recording to fit the level within a minimum and maximum range.
A peak programme meter (PPM) is an instrument used in professional audio that indicates the level of an audio signal. Different kinds of PPM fall into broad categories: True peak programme meter. This shows the peak level of the waveform no matter how brief its duration. Quasi peak programme meter (QPPM). This only shows the true level of the ...
[1] [2] In acoustics, a formant is usually defined as a broad peak, or local maximum, in the spectrum. [3] [4] For harmonic sounds, with this definition, the formant frequency is sometimes taken as that of the harmonic that is most augmented by a resonance. The difference between these two definitions resides in whether "formants" characterise ...
The commonly given measurement of PMPO (peak music power out) is largely meaningless and often used in marketing literature; in the late 1960s there was much controversy over this point and the US Government (FTA) required that RMS figures be quoted for all high fidelity equipment. Music power has been making a comeback in recent years.
A similar template for use when citing sources for musical singles can be found at Template:Single chart; however, for EPs or other releases, it has not yet been developed. In general, the template expands to produce a table row with the information country, record chart, reference, and peak position for the given album on the particular chart ...
