What Is an AI Audio Cleaner?
An audio cleaner — also called a background noise remover — is an AI tool that strips unwanted sound out of a recording while keeping the voice or instrument clear. StemSplit's AI audio cleaner uses neural speech enhancement to separate the sound you want from the noise you don't, so you can remove background noise from audio and video online in seconds, with no software to install.
Traditional noise reduction relied on noise gates and EQ filters that often left voices sounding thin, muffled, or robotic. A modern AI audio cleaner is trained on thousands of real-world recordings, so it learns the difference between human speech and steady background noise. The result is a natural clean-up that removes hiss, hum, and room echo without the underwater artifacts of old-school filters.
Voice Cleaner vs Vocal Remover: Which Do You Need?
Use the Voice Cleaner
When you want to keep the voice and remove background noise — hiss, hum, echo, wind, or HVAC — from podcasts, interviews, calls, and videos. The speech stays; the noise goes.
Use the Vocal Remover
When you want to split a song into vocals and instruments — to make karaoke tracks, acapellas, or isolated stems. It separates music; it's not for cleaning up noise.
Rule of thumb: cleaning up a noisy recording → Voice Cleaner. Removing or isolating the singing in a song → Vocal Remover.

What Background Noise Can It Remove?
StemSplit's background noise remover handles the most common problems that ruin a recording:
- HVAC, air-conditioning, and fan hum
- Electrical hiss and 50/60 Hz mains hum
- Room reverb and echo from untreated spaces
- Wind noise on outdoor and field recordings
- Keyboard typing, mouse clicks, and handling noise
- Traffic, crowd, and general ambient room noise
Need to do more than clean up noise? StemSplit can also separate a song into vocals, drums, bass, and other stems — so you can build clean acapellas or instrumentals from the very same upload.
Voice Cleaner Free — FAQ
How noise removal works, what formats we support, and how the free plan works
How does the AI voice cleaner work?
Upload your audio or video file and StemSplit's neural noise reduction model analyzes the recording, identifies background noise patterns (hiss, hum, room echo, HVAC noise), and removes them while preserving the original voice or instrument. Results are ready in seconds.
Is this voice cleaner free?
Yes — sign up and get 5 free minutes with no credit card required. After that, credits start at $0.10 per minute with no subscription and no expiry. You only pay for what you use.
What is the best free background noise remover online?
StemSplit Voice Cleaner uses a state-of-the-art neural network for speech enhancement. It handles a wide range of noise types — HVAC hum, keyboard clicks, wind, and room echo — while preserving natural voice quality. 5 free minutes on signup, no subscription required.
How do I remove background noise from a video?
Upload your video file (MP4, MOV, or WEBM) and StemSplit extracts the audio track, removes background noise, hiss, wind, and room echo, then returns a clean audio file you can re-attach in your editor. It's ideal for YouTube videos, Reels, TikToks, and recorded calls where the original footage was noisy.
How is this different from Audacity, Adobe Podcast, or Krisp?
Audacity's noise reduction needs a manual noise profile and can sound robotic; Krisp works in real time during calls but not on existing files; Adobe Podcast Enhance is web-based like StemSplit. StemSplit runs AI speech enhancement on your uploaded file in seconds with no software to install, supports both audio and video, and also offers full stem separation — all on pay-as-you-go credits with no subscription.
What kinds of noise can be removed?
Our AI can remove a wide range of background noise: HVAC / air conditioning hum, fan noise, keyboard typing, mouse clicks, room reverb and echo, traffic noise, wind, electrical hiss, 50/60 Hz hum, and general ambient room noise. It works best on recordings where the voice or instrument is clearly the main source.
Will removing noise reduce the audio quality?
No — the AI is trained to separate noise from the voice rather than simply filtering frequencies, so the cleaned recording keeps its natural tone and clarity. You can download the result in lossless WAV or FLAC at the same bit depth as your original, with no compression artifacts.
What audio and video formats are supported?
You can upload MP3, WAV, FLAC, M4A, OGG, WEBM, and MP4 video files up to 100MB. Cleaned audio can be downloaded in WAV (lossless), MP3, or FLAC format.
Can I also separate stems like vocals and drums?
Yes — StemSplit can do full stem separation in addition to noise removal. Split any song into up to 5 stems: vocals, drums, bass, melody, and other. You can even combine noise removal with vocal extraction — perfect for creating clean acapella tracks.
