Wi-Fi environments, said the company. Novus Labs recorded the number of audio dropouts and glitches that occurred over a 10-minute period with different levels of Wi-Fi traffic congestion (baseline, 25%, 50%, 75%, and 100% congestion). Overly congested networks can result in audible audio dropouts and glitches affecting Quality of Service. Most audio products on the market manage this by detecting heavily trafficked wireless channels and quickly switching to open channels, commonly referred to as “detect and avoid,” WiSA said. As the number of wireless devices increases in homes, it has become difficult to avoid congestion, and products using “detect and avoid” can no longer guarantee a high level of QoS, WiSA said. The Novus test results showed WiSA DS’ reliability is 1.5-3 times better than competitive 5 GHz products in the market, the company said. The DS module transmits up to four separate audio channels plus a low-frequency subwoofer channel; a single model in RX mode can output two audio channels. Fixed low latency meets the ITU and Dolby specifications for lip-sync, said WiSa.
