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 {{single chart}} template is available for formatting chart tables for single articles and the {{album chart}} template is for album articles. The use of the templates is strongly encouraged, as they automatically create a correct reference for the chart entry, allow changes to sourcing sites to be accommodated by editing a central location ...
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 signal at +4 dBu is equivalent to a sine wave signal with a peak amplitude of approximately 1.736 volts, or any general signal at approximately 1.228 V RMS. Peak-to-peak (sometimes abbreviated as p-p ) amplitude (V PP ) refers to the total voltage swing of a signal, which is double the peak amplitude of the signal.
[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 specification of weighted CCIR-468 quasi-peak noise, and weighted quasi-peak wow and flutter became particularly widely used and attempts were made to find more valid methods for distortion measurement. Measurements based on psychoacoustics, such as the measurement of noise, often use a weighting filter.

The peak-to-average power ratio (PAPR) is the peak amplitude squared (giving the peak power) divided by the RMS value squared (giving the average power). [1] It is the square of the crest factor. When expressed in decibels , crest factor and PAPR are equivalent, due to the way decibels are calculated for power ratios vs amplitude ratios .
