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 channels
• Uncompressed audio ^[6]
  • Bit depth: Up to 24 bits per channel
  • Sample rate: Up to 96 kHz
• 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 × 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]
