About Hiss & Sibilance
Hiss is that constant high-pitched noise that plagues recordings from analog gear, high-gain mic settings, or old tape media. This tool figures out the hiss profile and pulls it down while keeping the natural brightness and detail of your voice.
Tips for Better Results
- Use a low-noise mic preamp. Tube preamps tend to introduce more hiss than solid-state ones.
- Keep gain levels moderate. Recording a bit quieter is better than pushing gain into the noise floor.
- If you are digitizing old tapes, use the best playback equipment you can find to minimize added noise.
- A pop filter can help tame sibilance (harsh "s" sounds) before it even hits the mic.
