Helps users (particularly those with ADHD) maintain focus by transforming standard stereo audio into an immersive, rotating surround-sound experience.

1. User installs the extension. 2. User navigates to a page with audio/video content and starts playback. 3. User clicks the extension icon to open the popup. 4. Popup detects if audio is playing; if so, the 'Enable 8D' button becomes active. 5. User clicks 'Enable 8D', which sends a message to the background service worker. 6. The service worker injects a content script that creates an AudioContext, connects the media element through a rotating PannerNode (HRTF), and applies the 8D spatial effect. 7. Tab title updates to show '8D🔊'. 8. Clicking again disables the effect and restores normal audio.

Target users: People with ADHD seeking focus aids / Users interested in immersive/8D audio experiences / General Chrome users

The extension is very small (11.49 KiB) with minimal code, so analysis is straightforward. However, the actual audio processing behavior depends on the Web Audio API implementation in the injected content script, which we inferred from code inspection rather than runtime testing. No external API calls were detected beyond the Chrome Web Store update URL, but we did not test for dynamic network requests at runtime.

Monetization

No paid features detected

The extension is entirely free with no paywalls, subscriptions, or premium tiers. The 'pro' keyword match in the static scan was a false positive from the word 'description' in manifest.json. No payment platforms, billing APIs, or upgrade prompts were found anywhere in the codebase.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension performs all local audio processing via Web Audio API and content scripts. There is no login UI, no account creation, no session management, and no network requests to any authentication or user-profile endpoints. The only external host is Google's CRX update URL.
