Webchat Audio Notifications

**Verdict:** A focused, production-ready browser audio notification layer for Moltbot/Clawdbot-style webchats. Well-designed for desktop/laptop use with modern browsers; less ideal for mobile-only scenarios. **Strengths** - **Smart behavior:** Only plays when the tab is hidden, which avoids constant noise while the user is actively in chat. - **Granular control:** Five intensity levels, volume slider support, and configurable cooldown provide good tuning for different event types. - **Integration quality:** Clear API (`init`, `notify`, `setVolume`, `setSound`, etc.), example code, and an integration guide for Moltbot + React/Vue. - **Lightweight & safe:** Small footprint, uses Howler.js, no external network calls, and stores only preferences in `localStorage`. **Risks / Limitations** - **Browser / mobile constraints:** Relies on Web Audio API and browser autoplay rules; mobile support is explicitly “limited,” and iOS will often require a user gesture before sounds play. - **UX risk of annoyance:** High-intensity levels can be disruptive if misconfigured (e.g., very loud level5 plus short cooldown), especially in shared or quiet environments. - **Accessibility gaps:** Purely audio-based notifications may not serve hearing-impaired users; visual fallbacks are only on the roadmap, not built-in. - **Tab-state assumptions:** The “only when tab is hidden” logic is correct for most workflows but might surprise users who expect sounds even when the tab is visible but not focused. **Best-fit scenarios (recommended)** - Desktop web users who keep Moltbot/Clawdbot open in a background tab while working in other apps and want reliable, configurable audio cues. - Moderation / support teams who need to differentiate event types (e.g., normal message vs. mention vs. DM) using different intensities and volumes. - Deployments where privacy and security are strict: no tracking, no external calls, and a simple, auditable codepath are important. **Use with caution** - Mobile-heavy user bases, particularly iOS, where autoplay constraints and limited support will degrade the experience. - Quiet or shared workspaces where “impossible-to-miss” sounds may be socially unacceptable unless defaults are tuned conservatively and users can easily disable or soften alerts.
