(WIreless Speaker and Audio) A wireless audio standard from the WiSA Association, Sunnyvale, CA, www.wisaassociation.org. WiSA is used to transmit multichannel, high-definition audio wirelessly between A/V components. Debuting in 2011 and pronounced "why-suh," WiSA supports up to eight channels of uncompressed digital audio at 96 kHz, 24-bit resolution (see 96/24).The speakers must be identified for the WiSA transmitting device, such as a TV, Blu-ray player or stand-alone WiSA transmitter (see image below). This can be done manually on a TV or tablet, or automatically with speakers that ultrasonically "ping" each other to detect locations and channel assignments.Adjust the Sweet Spot for Better ListeningWhen listening to a WiSA-compliant home theater, users can identify their current location in the room, and the system adjusts speaker delay and volume to make their seat the sweet spot for listening.The Unlicensed U-NII BandTransmitting in the unlicensed U-NII 5 GHz band, WiSA uses dynamic frequency selection (DFS) to change channels when interference is detected. WiSA transmitters are always looking ahead for another channel to switch to if necessary (see U-NII). See high-resolution audio.
