Description
Reduce background noise and normalize audio levels using GPU acceleration.
How to Use
1
1. Provide a publicly accessible audio URL.
2
2. Enable `denoise` to apply noise reduction (default: `true`).
3
3. Enable `normalize` to normalize audio levels (default: `true`).
4
4. Optionally set `target_db` to specify the target loudness in dB LUFS (default: `-16.0`).
About This Tool
Clean up audio recordings with GPU-accelerated noise reduction and loudness normalization. Removes background hiss, hum, and ambient noise while normalizing volume to a consistent level.
Ideal for cleaning up podcasts, voice memos, field recordings, and any audio captured in less-than-ideal environments.
Why Use This Tool
- Podcast cleanup — Remove background noise from interview recordings
- Voice memo enhancement — Clean up phone recordings for better clarity
- Field recording — Reduce wind noise and ambient sound
- Pre-processing — Clean audio before feeding into transcription
Frequently Asked Questions
Will this remove all background noise?
It significantly reduces steady-state noise like hiss, hum, and ambient room tone. It won't remove transient sounds like door slams or overlapping speech.
Does it affect voice quality?
The algorithm is tuned to preserve speech clarity. Minor artifacts may occur on extremely noisy recordings, but conversational speech remains natural.
