## Review summary

The Audio Compressor add-on is highly praised for cross-site effectiveness, per-site settings, and vocal clarity via dynamic compression, plus convenient presets. However, several reviews report site-specific audio failures (Twitch, GitHub, Factorio) and occasional artifacts or inconsistent behavior on certain pages. Overall, it's a valuable Firefox extension for balancing volume and protecting hearing, with notable room for improvement in site compatibility and consistency.

### Pros

- Works across many sites (YouTube, Twitch, Netflix, Spotify, and more) and handles varying volumes between streams and videos.
- Remembers per-site (per-page) settings, so each website keeps its own compression profile.
- Dynamic range compression reduces loud spikes while keeping dialogue audible, with optional boost for quiet sections.
- Offers presets for quick, one-click adjustments and generally doesn't require refreshing tabs.

### Cons

- Site compatibility issues can cause audio problems on some sites (notably Twitch, GitHub, and Factorio), including muted or missing audio when enabled.
- Audio artifacts such as phasing or doubling can occur on certain configurations.
- Results can be inconsistent across sites or setups, with some users reporting little or no effect on certain pages.
