Mastering + voice clean-up

Make it sound pro.

Music gets mastered. Voices get cleaned. Pick what you have and where it’s going — we handle the rest.

Drop a song or a recording

MP3, WAV, M4A, FLAC — or a video, we’ll use its sound

Stays on your device. Nothing is uploaded.

How it works

  1. Drop your audio

    A song, a podcast episode, a voice-over or a video’s soundtrack.

  2. Pick music or voice

    Then choose where it’s going: Spotify, YouTube, TikTok or a podcast app.

  3. Compare and download

    Flip between before and after in one tap. Download as WAV or MP3.

What it does to your sound

For music, it listens to your whole track first, compares its tone with a balanced reference, and then corrects it: dull mixes get air and presence, harsh ones get smoothed, thin ones get body. A gentle multiband compressor glues it together and a true-peak limiter brings it to the right loudness for your platform.

For speech, a neural noise suppressor removes hiss, hum, fans, traffic and room noise. Then an automatic leveler brings quiet and loud speakers to the same volume, a de-esser tames sharp “s” sounds, and the result is set to the loudness podcast apps and video platforms expect.

AI-made songs (Suno, Udio and others) often sound muffled or brittle. That’s exactly the kind of thing the music mode is tuned for.

Questions

Is the audio enhancer really free?
Yes. No account, no watermark, no limit on how many files you process. The site is paid for by ads.
Do you upload my audio?
No. All processing happens inside your browser, on your own device. Your file never leaves your computer or phone.
What loudness do you master to?
Spotify and YouTube: −14 LUFS. TikTok & Reels: −12 LUFS. Apple Music: −16 LUFS. Podcasts: −16 LUFS. Video: −14 LUFS. Peaks are kept below −1 dBTP so streaming services don’t distort your track.
Can it fix AI songs from Suno or Udio?
It’s great at making them sound clearer, fuller and louder. It can’t re-record bad vocals, but most AI tracks sound noticeably more finished after mastering.
Which file types work?
MP3, WAV, M4A, AAC, FLAC, OGG and the audio inside MP4, MOV or WebM videos. You download WAV (best quality) or MP3.
How is this different from the before/after on other sites?
Our switch plays both versions perfectly in sync, so you hear the difference at the exact same moment in the song.
