Today we're launching **[Voice Cleaner](/voice-cleaner)**, StemSplit's free AI background noise remover that cleans up any audio or video file in seconds. **TL;DR**: Voice Cleaner is a free online AI audio cleaner that removes background noise, HVAC hum, electrical hiss, wind, and room echo while keeping voices natural. Upload any audio or video file (MP3, WAV, FLAC, M4A, OGG, WEBM, or MP4 up to 100MB), let the neural speech-enhancement model process it, and download clean audio in lossless WAV/FLAC or MP3. You get **5 free minutes on signup** with no credit card, then pay-as-you-go credits from **$0.10/min** — no subscription. It also ships with five dedicated noise-type tools: [echo remover](/voice-cleaner/echo-remover), [wind noise remover](/voice-cleaner/remove-wind-noise), [hum remover](/voice-cleaner/hum-remover), [hiss remover](/voice-cleaner/hiss-remover), and [static noise remover](/voice-cleaner/remove-static-noise). ## What Is Voice Cleaner? Voice Cleaner is an **AI audio cleaner** — a tool that strips unwanted sound out of a recording while keeping the voice or instrument clear. Instead of the noise gates and EQ filters of old-school noise reduction (which often leave voices thin, muffled, or robotic), Voice Cleaner uses a neural speech-enhancement model trained on thousands of real-world recordings. It learns the difference between human speech and steady background noise, so the clean-up sounds natural rather than underwater. It runs entirely in your browser — there's nothing to install — and works on both audio files and the audio track inside video files. ## What Noise Can It Remove? Background noise comes in two kinds: **steady noise** that stays constant (hiss, hum, buzz) and **sudden noise** (clicks, coughs, passing traffic). Voice Cleaner handles both, including the most common recording-killers: - 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 ## How to Remove Background Noise From Audio or Video Three steps, no audio-editing experience required: 1. **Upload your file** — Drag in any MP3, WAV, FLAC, M4A, OGG, WEBM, or MP4 video file up to 100MB. 2. **Let the AI clean it** — The neural model detects and removes background noise, hiss, hum, wind, and reverb in seconds. There are no settings to tweak. 3. **Download clean audio** — Export the cleaned track in lossless WAV or FLAC, or compressed MP3 — ready for your podcast, video, or mix.

Alongside the general cleaner, Voice Cleaner includes five purpose-built pages, each with method-by-method guidance for that specific problem: | Tool | Best for | Typical cause | |---|---|---| | [Echo & Reverb Remover](/voice-cleaner/echo-remover) | Voices recorded in hard, empty rooms or on a phone | Sound reflecting off walls and surfaces | | [Wind Noise Remover](/voice-cleaner/remove-wind-noise) | Outdoor and field recordings | Air hitting an unshielded mic | | [Hum Remover](/voice-cleaner/hum-remover) | Low droning under speech | HVAC, fans, and 50/60 Hz electrical hum | | [Hiss Remover](/voice-cleaner/hiss-remover) | Constant high-frequency "shhh" | Tape hiss, mic self-noise, white noise | | [Static Noise Remover](/voice-cleaner/remove-static-noise) | Crackle and intermittent interference | Loose cables, contacts, and radio interference | Each tool routes to the same AI engine, so you can also start from the [main Voice Cleaner page](/voice-cleaner) and let it handle a mix of problems at once. ## Voice Cleaner vs. Vocal Remover: Which Do You Need? These two tools sound similar but solve different problems: | Task | Use this tool | |---|---| | Keep the voice, remove background noise (hiss, hum, echo, wind) | **[Voice Cleaner](/voice-cleaner)** | | Split a song into separate vocal and instrumental tracks | **[Vocal Remover](/vocal-remover)** | In short: if you're **cleaning up a noisy recording**, use Voice Cleaner. If you're **isolating or removing the singing in a song** (for karaoke, acapellas, or stems), use the Vocal Remover. Voice Cleaner enhances one recording; Vocal Remover separates a song into its parts. ## Who It's For - **Podcasters** — Clean up noisy home-studio recordings and remote interview audio without acoustic treatment. - **Content creators** — Remove background noise from YouTube, Reels, and TikTok voiceovers. - **Remote workers** — Enhance recorded meetings, webinars, and online calls. - **Musicians** — Clean up vocal recordings before mixing and production, or combine noise removal with [stem separation](/stem-splitter) to build clean acapellas. ## FAQ ### 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 because the model separates noise from speech rather than simply filtering frequencies. ### Is 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. ### 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. ### Can it remove echo and reverb from a recording? Yes. Light to moderate room echo from untreated spaces or phone recordings cleans up well — the AI reduces the reverb tail while keeping the voice natural. Very heavy, cave-like reverb can be reduced but not removed completely. For a focused workflow, use the dedicated [Echo & Reverb Remover](/voice-cleaner/echo-remover). ### 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. Voice Cleaner runs AI speech enhancement on your uploaded file in seconds with no software to install, supports both audio and video, and shares an account with full stem separation — all on pay-as-you-go credits with no subscription. ### Will removing noise reduce the audio quality? No — the AI is trained to separate noise from the voice rather than filter 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. ### Can I also separate stems like vocals and drums? Yes. The same account that powers Voice Cleaner can split any song into up to 5 stems — vocals, drums, bass, melody, and other — with the [Stem Splitter](/stem-splitter). You can even combine noise removal with vocal extraction to create clean acapella tracks. --- ## Start Cleaning Your Audio Every recording you upload to Voice Cleaner gets professional-grade noise removal in seconds. - ✅ Removes background noise, hum, hiss, wind, and echo - ✅ Works on audio and video — nothing to install - ✅ Lossless WAV/FLAC or MP3 output - ✅ 5 free minutes on signup, no subscription [Try Voice Cleaner Free →](/voice-cleaner) --- *This article was originally published at https://stemsplit.io/blog/voice-cleaner.
