Windows 7 and newer. Diamond Cut Audio Restoration Tools (also known as DC-Art and Diamond Cut Audio Lab) is a set of digital audio editor tools from Diamond Cut Productions used for audio restoration, record restoration, sound restoration of gramophone records and other audio containing media.
This example created using demo_tv.m by Guy Gilboa, see external links. In signal processing, particularly image processing, total variation denoising, also known as total variation regularization or total variation filtering, is a noise removal process ( filter ). It is based on the principle that signals with excessive and possibly spurious ...
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio .
This category collects Wikipedia articles on techniques for removal or reduction of noise and artifacts from images and multi-dimensional data. Pages in category "Image noise reduction techniques" The following 19 pages are in this category, out of 19 total.
Video denoising. Video denoising is the process of removing noise from a video signal. Video denoising methods can be divided into: Spatial video denoising methods, where image noise reduction is applied to each frame individually. Temporal video denoising methods, where noise between frames is reduced. Motion compensation may be used to avoid ...
Click removal. In audio restoration and audio editing, hardware and software de-clickers provide click removal or de-clicking features. A spectrogram can be used to visually detect clicks and crackles (corrective spectral editing). See also. Crackling noise; Record restoration; Gaussian noise; Impulse noise (acoustics)
Noise control is an active or passive means of reducing sound emissions, often for personal comfort, environmental considerations, or legal compliance. Active noise control is sound reduction using a power source. Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather ...
Signal averaging. Signal averaging is a signal processing technique applied in the time domain, intended to increase the strength of a signal relative to noise that is obscuring it. By averaging a set of replicate measurements, the signal-to-noise ratio (SNR) will be increased, ideally in proportion to the square root of the number of measurements.
