Digital room correction may involve minimum phase algorithms, to maintain wavefront coherence over the intended frequency range.. The use of analog filters, such as equalizers, to normalize the frequency response of a playback system has a long history; however, analog filters are very limited in their ability to correct the distortion found in many rooms.
Room modes are the collection of resonances that exist in a room when the room is excited by an acoustic source such as a loudspeaker. Most rooms have their fundamental resonances in the 20 Hz to 200 Hz region, each frequency being related to one or more of the room's dimensions or a divisor thereof. These resonances affect the low-frequency ...
Audyssey Dynamic EQ: A technology that solves the problem of deteriorating sound quality as the playback volume is decreased. Dynamic EQ combines information from incoming source levels and actual output sound levels in the room or car to make moment-by-moment adjustments that compensate for the changes in human hearing at different listening levels.
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer .
Room acoustics is a subfield of acoustics dealing with the behaviour of sound in enclosed or partially-enclosed spaces. The architectural details of a room influences the behaviour of sound waves within it, with the effects varying by frequency .

Early telephone systems used equalization to correct for the reduced level of high frequencies in long cables, typically using Zobel networks.These kinds of equalizers can also be used to produce a circuit with a wider bandwidth than the standard telephone band of 300 Hz to 3.4 kHz.
Real-Time Object-Oriented Modeling (ROOM) is a domain-specific language. ROOM was developed in the early 1990s for modeling real-time systems . [ 1 ] The initial focus was on telecommunications , even though ROOM can be applied to any event-driven real-time system.
