  3. Click (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Click_(acoustics)

    On phonograph records, clicks are perceived in various ways by the listener, ranging from tiny 'tick' noises which may occur in any recording medium through 'scratch' and 'crackle' noise commonly associated with analog disc recording methods. Analog clicks can occur due to dirt and dust on the grooves of the vinyl record or granularity in the ...

  4. Noise reduction - Wikipedia

    en.wikipedia.org/wiki/Noise_reduction

    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.

  6. Audio restoration - Wikipedia

    en.wikipedia.org/wiki/Audio_restoration

    Audio restoration is the process of removing imperfections (such as hiss, impulse noise, crackle, wow and flutter, background noise, and mains hum) from sound recordings. Audio restoration can be performed directly on the recording medium (for example, washing a gramophone record with a cleansing solution), or on a digital representation of the ...

  7. Audio editing software - Wikipedia

    For example, stock plug-ins are the plug-ins that come already installed with a DAW, and Virtual Studio Technology (VST) plug-ins. Invented by Steinberg, VST plug-ins allow producers to apply simple or advanced effects such as filters, limiting, compression, reverb, flanging, panning, noise reduction, and equalizers.

  8. Dynamic range compression - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range_compression

    Noise reduction systems use a compressor to reduce the dynamic range of a signal for transmission or recording, expanding it afterward, a process called companding. This reduces the effects of a channel or recording medium with limited dynamic range.

  9. Noise shaping - Wikipedia

    en.wikipedia.org/wiki/Noise_shaping

    Noise shaping is a technique typically used in digital audio, image, and video processing, usually in combination with dithering, as part of the process of quantization or bit-depth reduction of a signal.
