In digital and analog audio, headroom refers to the amount by which the signal-handling capabilities of an audio system can exceed a designated nominal level. [1] Headroom can be thought of as a safety zone allowing transient audio peaks to exceed the nominal level without damaging the system or the audio signal, e.g., via clipping.
A DJ gets his decks ready as the speaker cabinets are set up and readied for a dance event. A challenge with designing sound systems for clubs is that the sound system may need to be used for both prerecorded music played by DJs and live music. A club system designed for DJs needs a DJ mixer and space for record players. In contrast, a live ...
Dialnorm is the metadata parameter that controls playback gain within the Dolby Laboratories Dolby Digital (AC-3) audio compression system. Dialnorm stands for dialog normalization. [ 1 ] Dialnorm is an integer value with range 1 to 31 corresponding to a playback gain of −30 to 0 dB (unity) respectively.
A digital representation expresses the audio waveform as a sequence of symbols, usually binary numbers. This permits signal processing using digital circuits such as digital signal processors, microprocessors and general-purpose computers. Most modern audio systems use a digital approach as the techniques of digital signal processing are much ...

The digital audio signal, whose origin may be analog (by conversion to digital) or be in an already digital source (such as an audio file, or a software synthesizer), is stored in temporary allotments of computer memory called buffers. Once there, the software effect processor modifies the signal according to a specific algorithm, which creates ...
