LG has officially denied allegations that its smart TVs are spying on users by recording audio, scanning local networks, and logging data while in standby mode. The company dismissed these tracking and snooping concerns as completely false.

A new Show HN project allows users to visualize audio through their webcams, though early testers report it struggles with voice detection. Users noted that the tool generates random visual patterns in quiet rooms because webcam microphones use auto-gain to amplify background noise. Despite these sensitivity issues, the application reportedly works well for capturing other distinct sounds.

YuE2 is a new AI model that unifies symbolic and audio music generation to produce high-quality tracks. The system uses symbolic planning to convert user-provided lyrics and style prompts into an editable musical score.
