surround sound

Surround Sound
Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (centre, [front] left, and [front] right) originating only from the listener's forward arc.
Surround sound is characterized by a listener location or sweet spot where the audio effects work best, and presents a fixed or forward perspective of the sound field to the listener at this location. The technique enhances the perception of sound spatialization by exploiting sound localization; a listener's ability to identify the location or origin of a detected sound in direction and distance. Typically this is achieved by using multiple discrete audio channels routed to an array of loudspeakers.

    Freesat 4k surround sound progress

    This has been mentioned in other posts since its launch, but has not been fixed, and does not look like it ever will be until the next generation STB possibly. The channel data flag from the Freesat 4k box gives out a fixed signal depending on what the audio options have been set to, so it...

    Clueless. Should i upgrade my 13 year old Surroind Sound system?

    I hear sound bars have gotten really good. But I've always been a surround sound multi speaker person. I've owned a total of 2 systems over a span of 25 years or so. My current setup is 13 years old. Works just fine. But I can't help wondering if I'd notice a big difference if I bought a new...

    Question Placement of subwoofer in home cinema surround sound (Logitech Z906)

    I have my TV on an open front cabinet. I could put the subwoofer in the cabinet (and remove most of the back of it to allow airflow, it's a panel that can be removed) or I could put it behind the cabinet. If I put it in the cabinet I would slide it to the left so there is max room in front of...

    Is it possible to get surround sound with wireless connection from a laptop/computer?

    My TV can process multichannel sound to my home cinema system and last weekend for the first time I tried casting my laptop to the TV successfully but it is only a stereo sound with the picture. Is there anyway of processing a multichannel sound from the laptop as it is digital audio being sent?
