If you are about to purchase a brand new home theater system then chances are that you are considering to get some wireless rear speakers. Going wireless has the advantage that you won’t have to install long speaker cords throughout your room. Many vendors of home theater systems have started to offer wireless-ready receivers which take a plug-in transmitter that can send the rear-speaker audio channels wirelessly to a wireless receiver. I am going to take a look at audio latency of the wireless option and explain in how far this latency affects the sound experience.
After you have picked a home theater system, you should check out whether this system is wireless ready. If so, you can get an add-on transmitter. If not, you can get a universal wireless speaker kit. You can get more info about wireless speaker kits at http://www.amphony.com/products/wireless-surround-sound.htm. Wireless kits will convert the audio for the rear speakers to data. During the wireless transmission, a fair amount of data is stored inside memory chips so that lost data packets can be resent in case of errors during the transmission. The more buffering is done, the more reliable the transmission is. However, a large latency will cause sync problems and thus you want to keep it below 30 ms.An Explanation Of The Term "Latency" Of Wireless Surround Speakers by GM MyLink
