The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. [1] It uses five full-bandwidth channels and one low-frequency effects channel (the "point one"). [2]
Atmos in home theaters can support 24.1.10 channels [15] [51] and uses the spatially-encoded object audio sub-stream to mix the audio presentation to match the installed speaker configuration. There are programs from Dolby that handle 128 objects (including 118 dynamic objects and 10 beds) for macOS and Windows. [52]
Matrix decoding is an audio technology where a small number of discrete audio channels (e.g., 2) are decoded into a larger number of channels on play back (e.g., 5). The channels are generally, but not always, arranged for transmission or recording by an encoder, and decoded for playback by a decoder.
The first and simplest method is using a surround sound recording technique—capturing two distinct stereo images, one for the front and one for the back or by using a dedicated setup, e.g., an augmented Decca tree [20] —or mixing-in surround sound for playback on an audio system using speakers encircling the listener to play audio from ...
DTS-HD Master Audio (DTS-HD MA; known as DTS++ before 2004 [1]) is a multi-channel, lossless audio codec developed by DTS as an extension of the lossy DTS Coherent Acoustics codec (DTS CA; usually itself referred to as just DTS). Rather than being an entirely new coding mechanism, DTS-HD MA encodes an audio master in lossy DTS first, then ...
A Pro Logic decoder/processor "unfolds" the sound into the original 4.0 surround—left and right, center, and a single limited frequency-range (7 kHz low-pass filtered) [3] mono rear channel. A Pro Logic decoder also uses 'Steering Logic', which drives amplifiers to raise or lower the output volume of each channel based on the current dominant ...
Windows Media Player (or simply Media Player) is a video and audio player developed in UWP by Microsoft for Windows 11 and subsequently backported to Windows 10. It is the successor to Groove Music (previously Xbox Music), Microsoft Movies & TV , and the original Windows Media Player .
However, whereas a 5.1 surround sound system combines both surround and rear channel effects into two channels (commonly configured in home theatre set-ups as two rear surround speakers), a 7.1 surround system splits the surround and rear channel information into four distinct channels, in which sound effects are directed to left and right ...
