Roku has introduced a new Adjust audio delay tool within its mobile app to help users sync their Bluetooth or wired headphones with their TV. The feature utilizes a mobile device's camera and microphone to measure and resolve audio lag caused by wireless processing.

Why it matters

Bluetooth connectivity and network transmission often create delays that cause sound to fall behind video, frustrating viewers. This tool offers a simple calibration method to ensure that audio and visuals are perfectly aligned.

The new tool supports up to four simultaneously connected listening devices. It requires both the mobile device and the Roku hardware to be active on the same Wi-Fi network.
