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.
Apply simple or advanced effects or filters, including amplification, normalization, limiting, panning, compression, expansion, flanging, reverb, audio noise reduction, and equalization to change the audio. Playback sound (often after being mixed) that can be sent to one or more outputs, such as speakers, additional processors, or a recording ...
Batch processing allows users to apply effects and/or convert thousands of files as a single function; Scrub, search, and bookmark audio to find, recall and assemble segments of audio files; Spectral analysis (FFT), speech synthesis (text-to-speech), and voice changer; Audio restoration tools including noise reduction and click pop removal [4]
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.
It also has a large array of digital effects and plug-ins, [36] including: noise reduction based on sampling the noise to be minimized, [37] vocal reduction and isolation for creation of karaoke tracks and isolated vocal tracks, [38] pitch adjustment maintaining speed, and speed adjustment maintaining pitch.

Adobe Audition 2 was released on January 17, 2006. With this release, Audition (which the music recording industry had once seen as a value-oriented home studio application, although it has long been used for editing by radio stations) entered the professional digital audio workstation market.

POW-R (Psychoacoustically Optimized Wordlength Reduction) is a set of commercial dithering and noise shaping algorithms used in digital audio bit-depth reduction.Developed by a consortium of four companies – The POW-R Consortium – the algorithms were first made available in 1999 in digital audio hardware products.
