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, though independent power to the speakers is required.4

Technical specifications

  • Maximum channels:6 8 channels
  • Uncompressed audio6
  • Latency: 2.6 ms at 96 kHz, or 5.2 ms at 48 kHz6
  • Synchronization between speakers: ±2 μs6
  • Maximum supported room size:4 30 ft × 30 ft
  • Not designed to span multiple rooms4
  • Transmission band: U-NII 5 GHz spectrum6

WiSA has no support mandated for audio compression codecs.4 WiSA permits support for object-based surround sound schemes such as DTS:X or Dolby Atmos, though those features are not mandated in devices.4
