However, many dance and hip-hop musicians purposefully use this phenomenon, causing the mix to alter in volume rhythmically in time with the beat. [21] Hearing aids use a compressor to bring the audio volume into the listener's hearing range. To help the patient perceive the direction sound comes from, some hearing aids use binaural compression ...
Side-chain pumping is a more advanced technique using a compressor's side-chain feature which, "uses the amplitude envelope (dynamics profile) of one track as a trigger for a compressor used in another track." When the amplitude of a note of the side-chained instrument surpasses the threshold setting of the compressor it attenuates the ...
Compression has many uses in the mixing process, from evening out vocal volume to enhancing drums. [12]: 175 Limiters – Using a compression ratio of 10:1 or higher is known as limiting- instead of applying gentle reduction to audio above the threshold, limiters forcibly flatten it down, allowing no signal above the threshold. Many limiting ...
The data compression software for encoding into ALAC files, Apple Lossless Encoder, was introduced into the Mac OS X Core Audio framework on April 28, 2004, together with the QuickTime 6.5.1 update, thus making it available in iTunes since version 4.5 and above, and its replacement, the Music application.

Mastering, a form of audio post production, is the process of preparing and transferring recorded audio from a source containing the final mix to a data storage device (the master), the source from which all copies will be produced (via methods such as pressing, duplication or replication).
This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.
One way of stretching the length of a signal without affecting the pitch is to build a phase vocoder after Flanagan, Golden, and Portnoff.. Basic steps: compute the instantaneous frequency/amplitude relationship of the signal using the STFT, which is the discrete Fourier transform of a short, overlapping and smoothly windowed block of samples;
BandLab is an entry level music production app to make songs in various genres. [6] Free Audio & Vocal Preset effects, allowing users to change the sounds of vocals & other audio track sounds, for example 70s Funk bass, or robotic-sounding autotune vocals and other genre-specific sounds. The presets load and edit the free effects that BandLab ...
