The control for sample rate reduction (a.k.a. "downsampling" or "averaging") is sometimes shown in Hz for a new sample rate, or as a reduction factor. Sample rate reduction is sometimes shown instead as the number of consecutive samples to average together to create a new sample. A value of 20 reduces the sample rate to 1/20 of its original rate.

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.
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.
Audacious is a free and open-source audio player software with a focus on low resource use, high audio quality, and support for a wide range of audio formats. [6] It is designed primarily for use on POSIX-compatible Unix-like operating systems, with limited support for Microsoft Windows. [7]
Bit Rate Reduction, or BRR, also called Bit Rate Reduced, is a name given to an audio compression method used on the SPC700 sound coprocessor used in the SNES, as well as the audio processors of the Philips CD-i, the PlayStation, and the Apple Macintosh Quadra series. [1] The method is a form of ADPCM.
24-bit and 32-bit audio does not require dithering, as the noise level of the digital converter is always louder than the required level of any dither that might be applied. 24-bit audio could theoretically encode 144 dB of dynamic range, and 32-bit audio can achieve 192 dB, but this is almost impossible to achieve in the real world, as even ...
