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
[edit | edit source]- 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 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]
