Multi-channel audio has become mainstream and vendors have created many types of basic and more advanced technologies like wireless surround speakers, virtual surround sound to simplify the installation of home theater kits. I will look at the most recent trends to find out which devices in fact work. I will also give some guidance for selecting the ideal components.
For that reason, home theater setups have become relatively complex. Running wires to remote speakers also is often undesirable because of aesthetic reasons. Vendors have recently launched new devices and technologies. These products were created to help simplify the setup of home theater systems.
As a result the setup of home theater products has become a relatively complicated process. Many homes are not pre-wired for surround sound. Furthermore, long speaker cables are often unattractive. Vendors have recently launched new products and technologies. These devices were created to help simplify the setup of home theater systems. The first option is named virtual surround sound. This solution will take the audio components which would normally be broadcast by the remote loudspeakers. It then applies signal processing to those components and inserts special cues and phase delays. After that these components are mixed with the front speaker sound. The signal processing is designed based on how the human hearing determines the location of a sound. The audio signal is then broadcast by the front speakers. The signal processing has an effect that will deceive the listener into presuming that the audio is coming from an alternate location.
One option is reducing the number of speakers by building virtual speakers. This method applies signal processing to the sound and adds phase shifts and cues to the sound which would ordinarily be broadcast through the remote speaker. The signal processing is engineered according to how the human hearing determines the location of a sound. The audio signal is then broadcast through the front speakers. The signal processing has an effect that will trick the listener into presuming that the audio is originating from a different location.
This technology minimizes the number of needed loudspeakers and eliminates long speaker wires but each human will process sound slightly differently because of the shape of the ear. Because the signal processing is based on a standard human ear model, virtual surround will not function equally well for everybody depending on how much the viewer differs from the standard model. One more option for eliminating long speaker wire runs is to use wireless surround sound systems or wireless speakers. A wireless kit contains a transmitter and one or several wireless amplifiers. The transmitter connects to the source. The wireless amplifiers connect to the remote loudspeakers. The transmitter will normally have amplified speaker inputs in addition to line-level inputs and come with a volume control to adjust it to the source audio level.
As some wireless speaker systems come with a wireless amplifier that connects to two speakers, other products offer individual wireless amplifiers for every loudspeaker. The most sophisticated wireless systems utilize digital transmission to avoid signal degradation. Make certain that you select a wireless system with a low audio latency, at most a few milliseconds. This will guarantee that the sound from all loudspeakers, including the non-wireless speakers, is in sync. Low latency is also important for good sync with the video. Otherwise there will be a noticeable echo kind result. Many wireless products operate in the 900 MHz and 2.4 GHz frequency bands. A number of products use the less crowded 5.8 GHz frequency band and consequently have less competition from other wireless gadgets.
Another option are side-reflecting speakers. These kits are also known as sound bars. In this case the audio for the remote loudspeakers will be broadcast by individual loudspeakers positioned at the front at an angle and reflected by walls as to appear to be coming from besides or behind the viewer. This option works best in a square room with minimum interior design and obstacles. It will not function well in a lot of real-world scenarios with diverse room shapes however.
