Stereo to 7.1 Surround Upmixer by Silkworm Silks

Upmixes stereo audio to 7.1 surround in real-time

About this extension

This extension can upmix stereo tracks in real-time to fill up the unused channels in surround configuration setup, so you can now use all speakers to play the YouTube/TikTok/Instagram videos, music, and streams (since Google dropped the native surround sound support on YouTube through browsers).

Other features:
- Backwards-compatible to 5.1 and quadraphonic audio configurations.
- Mute and solo of the upmixed surround channels.
- Play local media files through Firefox browser using this extension to fill up all the speakers
- Compatible with H.264, AAC, VP9, AV1, AVC, and HEVC codecs
- Disable/enable at any time, if you want to play the native surround media like Facebook 360

Developer comments

Note: Upon installing this extension, please reload the page first to apply the upmix processing. This extension might not work on some sites, especially those which use DRMs (such as Netflix and Spotify), and online games like Rhythm Plus and the arcade/flash games played on the web, due to the limitations and incompatibilities of the Web Audio API, which this extension is based on.

Currently, this extension only has tested on YouTube, Pixabay, SoundCloud, and online radio sites.

This extension is NOT RECOMMENDED for those who use stereo speakers or headphones with virtualized/spatial surround effects.
