DaVinci Resolve is a proprietary color grading, color correction, visual effects, and audio post-production video editing application for macOS, Windows, and Linux, developed by Australian company Blackmagic Design.
Before loudness normalization, one song in a playlist might be quieter than the rest, so the listener would have to turn a volume knob up to adjust the playback volume. [ 4 ] Depending on the dynamic range of the content and the target level, loudness normalization can result in peaks that exceed the recording medium's limits, causing clipping.
Audio levels within phonograph, tape and broadcasting have traditionally been adjusted to keep peak levels within the physical and legal modulation limits of the medium. While this practice has resulted in relatively consistent dialog levels and has minimized audibility of channel noise, it has invited the use of excessive audio compression and ...
An audio pan pot can be used in a mix to create the impression that a source is moving from one side of the soundstage to the other, although ideally there would be timing (including phase and Doppler effects), filtering and reverberation differences present for a more complete picture of apparent movement within a defined space. Simple analog ...
Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.
These processes are often used to match the pitches and tempos of two pre-recorded clips for mixing when the clips cannot be reperformed or resampled. Time stretching is often used to adjust radio commercials [1] and the audio of television advertisements [2] to fit exactly into the 30 or 60 seconds available. It can be used to conform longer ...
A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio). A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level.

ReplayGain-capable audio players use the replay gain metadata to automatically attenuate or amplify the signal on a per-track or per-album basis such that tracks or albums play at a similar loudness level. The peak level metadata can be used to prevent gain adjustments from inducing clipping in the playback device. [2]
