Audio Presence - Spatial audio for co-viewing

Place each tab's audio in a virtual room. Hear co-viewing voices right beside you, or give videos a theater or concert sound.

Audio Presence lets you place the audio of each browser tab anywhere in a virtual room. Because you can clearly tell where each sound is coming from, it works especially well for co-viewing streams. Note: Designed for headphones or earphones. The interface is currently in Japanese only. Distance is simulated too, so placing a voice right beside you feels like someone is really watching next to you. You can also make everyday videos and music sound like a movie theater or a concert hall. How to use 1. Open the tab you want to place, click the extension icon, and add it as "content" (what you watch) or "co-viewing" (a streamer you watch along with). 2. Pick a preset for each tab. That's it. Drag the sound sources or yourself on the room map to move them freely. Besides the popup, you can add tabs from the page's right-click menu or with keyboard shortcuts (set them at chrome://extensions/shortcuts). If you want more control, fine-tune the sense of space, distance emphasis, speaking direction, bass boost and more, and save your settings as My Sets. Ways to use it - Listen to a chatting stream while you work, as if someone were talking beside you - Watch a movie with a co-viewing streamer whose voice sounds like they are in the room - Hear live recordings with the depth and power of a concert venue Features - Position: drag on the room map to set where each sound is and how wide it spreads - Room types: Living room, Theater and Concert hall add reverb sized to each room - Co-viewing voices: speaking direction, distance-based loudness, and how voices sound in each room and position - Bass boost: emphasize low sounds such as bass lines or engine rumble - Noise reduction (co-viewing tabs): reduces constant noise such as hiss or PC fan noise - Presets: many ready-made positions and settings are included - My Sets: save your own adjusted presets. Export and import make it easy to move to another browser or PC Limitations - To add a tab, operate on that tab while it is shown (a browser requirement) - Audio from internal browser pages such as chrome:// cannot be captured - Tab layouts are cleared when you close the browser (global settings are kept; save layouts as My Sets to keep them) - If the original audio is mono, widening it adds little spread (you can still move it anywhere in the room) - The interface is in Japanese only Privacy All audio processing and settings stay on your computer. Audio is never recorded, stored, or transmitted, and no personal data is collected. Privacy policy: https://a-00-manufacturer.github.io/developer-info/co-viewing-mixer/privacy.html
