Turn a noisy, echoey recording into clean, studio-clear speech with this free AI audio enhancer. Upload a podcast, voiceover, interview, Zoom clip or vocal take and AI removes background noise, hiss and room reverb, then restores the voice — you get a denoised version and a fully enhanced version to compare and download. No signup, no watermark.
It’s powered by a real speech-enhancement model (Resemble Enhance), so it’s built for voice — the kind of quick, dramatic clean-up that used to need a studio or an expensive plugin.
AI Audio Enhancer
Clean up a noisy voice recording with AI. Upload a podcast, voiceover, interview, vocal take or Zoom clip and get back a denoised version and a fully enhanced, studio-clear version — background noise, hiss and room echo removed, the voice restored. Free, no watermark.
Best for voice. This AI is trained on speech, so it shines on podcasts, voiceovers, interviews and vocal takes — not full music mixes. Your file is sent over an encrypted connection to our AI server, processed, and deleted right after (free: 3 enhancements/day). Just need quick, private noise removal with nothing uploaded? Use the instant Noise Reducer. Cleaning a vocal to mix? Pull it out first with the AI Stem Splitter.
How to enhance a voice recording
- Upload your recording (MP3, WAV, M4A, OGG or FLAC, up to 50 MB).
- Click Enhance with AI. It runs on our AI server and usually takes 20–60 seconds.
- Compare the versions. You get a Cleaned (denoised) take and an Enhanced (fully restored) take alongside your original.
- Download whichever sounds best — a clean, no-watermark WAV.
Cleaned vs Enhanced — which should I use?
Cleaned removes background noise and hiss while keeping your voice’s natural tone — the safe choice when the recording is already decent. Enhanced goes further: it rebuilds clarity and high-end detail for a polished, close-mic “studio” sound, ideal for rough or distant recordings. Because we return both from one run, you can simply pick the one that sounds right.
Best for voice — not full music
This model is trained on speech, so it’s outstanding on podcasts, voiceovers, interviews, audiobooks and lead vocals, but it isn’t designed for full music mixes. If you need to clean a vocal that’s buried in a song, separate it first with the AI Stem Splitter, enhance the isolated vocal here, then rebuild your mix. For quick, private noise removal that never uploads your file, the instant Noise Reducer uses spectral subtraction right in your browser — lighter, but great for steady hiss and hum.
Free, no watermark, studio-clear
Unlike some enhancers that cap length or stamp the output, every download here is a clean, full-quality WAV with no watermark — free for 3 enhancements a day. Your audio is sent over an encrypted connection, processed, and deleted right after; we don’t keep it.
Frequently asked questions
Is this AI audio enhancer free?
Yes — it’s free for 3 enhancements per day, with no signup and no watermark. You can download the cleaned and enhanced versions as full-quality WAV files.
What does it actually do?
It uses a two-stage AI model: a denoiser that removes background noise, hiss and hum, and an enhancer that restores clarity and detail to the voice — reducing echo and making speech sound close-mic’d and clean.
Does it work on music?
It’s trained on speech, so it’s best for voice — podcasts, voiceovers, interviews and vocals. On full music mixes results vary. To clean a vocal from a song, isolate it with the AI Stem Splitter first, then enhance it here.
Does my audio get uploaded?
Yes. Enhancement runs on our AI server, so your file is sent over an encrypted connection, processed, and deleted right after — we don’t store it. For a fully local option, use our browser-based Noise Reducer.
How is this different from the Noise Reducer tool?
The Noise Reducer runs instantly in your browser using spectral subtraction — private and great for steady hiss, but simpler. This AI Audio Enhancer uses a trained speech model that removes complex noise and reverb and rebuilds voice clarity, for a much stronger clean-up.
What formats can I upload and download?
Upload MP3, WAV, M4A/AAC, OGG or FLAC up to 50 MB. Your enhanced audio downloads as a WAV.
Can it remove echo and reverb?
Largely, yes — the enhancer reduces room echo and reverb as it restores the voice, which is why distant or roomy recordings often improve the most.
Why does my AI-enhanced voice sound robotic or over-processed?
The Enhanced version rebuilds clarity and high-end detail, which can sound artificial on a recording that was already decent. Try the Cleaned version instead, since it removes noise while keeping the voice’s natural tone, and compare both against the original before choosing.
Can the AI audio enhancer fix clipped or distorted audio?
The AI Audio Enhancer targets noise, hiss and room reverb, so heavy clipping from a recording that was too loud may only partly improve. Distortion is hard to undo once captured; record again with lower input gain if possible, leaving headroom below the loudest peaks.
How do I enhance a podcast episode longer than the 50 MB limit?
Split the episode into shorter sections or export it as a compressed MP3 to get under the 50 MB limit, then enhance each part. Keep the same version, Cleaned or Enhanced, on every section so the voice sounds consistent when the parts are joined back together.
How do I record a voice so it needs less clean-up?
Speak close to the microphone, record in a room with soft furnishings, and switch off fans, air conditioning and noisy devices. Set the input level so speech peaks well below clipping. A cleaner source always gives AI enhancement a better starting point.
What should I do with a podcast voice after AI enhancement?
Edit out mistakes, then apply gentle EQ and compression so the voice sits evenly, and bring the episode to a consistent loudness before publishing. The clean WAV is also a good source for transcription when show notes or captions are needed.
