StereoToMono is a Chrome extension built by Roman Slack that forces stereo audio into a single mono channel on any web page. With a simple on/off toggle, users can collapse left and right channels into consistent mono sound across all tabs, which is especially useful when wearing a single earbud, using one speaker, or dealing with content that has audio in only one channel.
The extension is intentionally minimal: version 1.0 is a lightweight package (around 23 KiB) that does one thing well. It is privacy-respecting by design, with the developer disclosing that no user data is collected, sold, or used for any purpose unrelated to its core audio-conversion function.
Published on the Chrome Web Store, StereoToMono has grown a real user base of a few hundred active installs, reflecting steady demand for a quick, no-friction way to normalize audio output in the browser.
