EBU R 128 is a recommendation for loudness normalisation and maximum level of audio signals. It is primarily followed during audio mixing of television and radio programmes and adopted by broadcasters to measure and control programme loudness. [1]
Another type of normalization is based on a measure of loudness, wherein the gain is changed to bring the average loudness to a target level. This average may be approximate, such as a simple measurement of average power (e.g. RMS), or more accurate, such as a measure that addresses human perception e.g. that defined by EBU R128 and offered by ReplayGain, Sound Check and GoldWave.
Audyssey Dynamic EQ: A technology that solves the problem of deteriorating sound quality as the playback volume is decreased. Dynamic EQ combines information from incoming source levels and actual output sound levels in the room or car to make moment-by-moment adjustments that compensate for the changes in human hearing at different listening levels.
ISO equal-loudness contours with frequency in Hz. An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. [1] The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness ...
The loudness war (or loudness race) is a trend of increasing audio levels in recorded music, which reduces audio fidelity and—according to many critics—listener enjoyment. Increasing loudness was first reported as early as the 1940s, with respect to mastering practices for 7-inch singles . [ 1 ]
Members of the LA Fire Department arrived onstage in full uniform to a lengthy standing ovation, and the two fire chiefs presented the award for Album of the Year, the final award of the broadcast.
Senate rules require a reconciliation bill’s provisions to have a direct impact on the budget. The Senate parliamentarian issues rulings on what is allowed to be included in the bill. But the ...
Equalization is commonly used to increase the depth of a mix, creating the impression that some sounds in a mono or stereo mix are farther away or closer than others. [3]: 75–76 Equalization is also commonly used to give tracks with similar frequency components complementary spectral contours, known as mirrored equalization. Selected ...
