YouTube Explores Audio Quality Controls for Premium Subscribers

The feature, currently in development, would allow users to choose from three audio presets but is expected to be exclusive to Premium members.

YouTube is testing a feature that enables users to control audio quality with three presets: Auto, Normal, and High.
The 'High' preset promises improved audio quality over the current standard 128kbps bitrate.
The feature is likely to be available only to YouTube Premium subscribers, continuing the trend of paywalling advanced features.
The 'Auto' preset is designed to adjust audio quality based on the user's internet connection.
Currently in development, the feature exists only as code in the YouTube Beta app, with no confirmed release timeline.
