WiSA is a hardware and software standard for wirelessly transmitting digital audio from an audio source to wireless speakers.[4] The standard is promoted by the Wireless Speaker and Audio Association (WiSA Association),[1] which comprises consumer electronics manufacturers, retailers, and technology companies.[5] The standard is based on technology from the WiSA Technologies corporation.[1]

WiSA removes the need to run speaker wires or RCA cables between an AV receiver (or similar device) and speakers in a home theater or home audio setup. However, cabling isn't completely eliminated; powered speakers are required, so the speakers need to be connected to electrical outlets.[4]

Technical specifications

  • Maximum channels:[6] 8
  • Uncompressed audio[6]
  • Latency: 2.6 ms at 96 kHz, or 5.2 ms at 48 kHz[6]
  • Synchronization between speakers: ±2 µs[6]
  • Maximum supported room size:[4] 30 ft x 30 ft
  • Not designed to span multiple rooms.[4]
  • Transmission band: U-NII 5 GHz spectrum[6]

WiSA doesn't mandate support for audio compression codecs.[4] WiSA permits, but doesn't require, support for object-based surround sound schemes such as DTS:X or Dolby Atmos.[4]
