Technology overview
Sound for movies, music, and games is created in calibrated and acoustically treated rooms. It is mixed at high reference levels using audio systems that can reproduce a wide dynamic range. At home and in the car there are many acoustical problems. We listen at lower levels that change our perception of bass and surround envelopment. Audyssey technologies remove these problems and enable you to experience sound as close as possible to the original.
MultEQ
Audyssey MultEQ is a room equalization solution that calibrates audio systems to achieve optimum performance for every listener in a large listening area. Based on multiple room measurements, MultEQ corrects for both time and frequency response problems in the home theater and performs a fully automated surround system setup.

Audyssey DSX
Audyssey DSX is a scalable system that adds Wide and Height speaker channels to expand the surround sound experience. Audyssey DSX first adds Wide channels for the biggest impact on envelopment and then creates Height channels to reproduce the next most important acoustical and perceptual cues. Audyssey DSX also uses Surround Envelopment Processing to enhance the blend between the front and surround channels.

Dynamic EQ
Audyssey Dynamic EQ makes moment-by-moment adjustments to compensate for changes in human hearing at lower listening levels. Content is mixed at very high levels, but most people listen at much lower levels, resulting in decreased bass and surround impression. Working in tandem with Audyssey MultEQ it restores the proper balance for every listener at any volume level. Learn more
Dynamic Volume
Audyssey Dynamic Volume solves the problem of wide volume variations between television programs, commercials, and various soft and loud passages of movies. It works in tandem with Audyssey Dynamic EQ so that as the playback volume is adjusted automatically, the perceived bass response, tonal balance, surround impression and dialog clarity remain the same. No more constant volume adjusting on the remote control!

BassXT and ABX
Audyssey BassXT and ABX enable subwoofers and smaller speakers to produce deeper bass by intelligently monitoring incoming audio signals and extending driver performance. This enables the system to produce lower frequencies than would be possible with a traditional system of the same size. Learn more
