What is AI mastering?
AI mastering is an automated process that applies professional audio mastering — EQ, compression, stereo widening and brick-wall limiting — to a mixed track, using machine-learning models trained on thousands of commercial releases. It delivers streaming-ready loudness and tonal balance in seconds, for free, without a human mastering engineer.
Choose Balanced, Warm, Bright, Punchy, or Loud to instantly match your artistic vision. Each preset applies EQ, compression, stereo widening, and loudness maximization.
A/B Comparison

Studio-Quality Output
Download your mastered track as a high-resolution WAV file. No quality loss, no artifacts, no watermarks — ready for streaming platforms or distribution.
100% Free & Private
All processing runs locally in your browser. Your music is never uploaded to any server. No signup, no trial period, no premium upsells.
How AI Mastering Works
RemoveVocals AI Mastering applies a professional-grade signal processing chain to your audio, running entirely in your browser. The mastering engine uses multi-band EQ shaping, dynamic range compression, stereo enhancement, and brick-wall limiting to deliver polished, release-ready sound.
Upload your track, and all presets are rendered simultaneously. Switch between Original and Mastered in real-time, compare presets instantly while listening, and adjust intensity to taste. When you find the sound you love, download as high-quality WAV.
RemoveVocals AI Mastering applies 5 professional presets (Balanced, Warm, Bright, Punchy, Loud) with one click — no audio engineering knowledge required.
Streaming platforms normalize to around -14 LUFS (Spotify, YouTube, Tidal, Amazon) or -16 LUFS (Apple Music), so hyper-loud masters are automatically turned down. Source: Spotify for Artists loudness docs.
Paid competitors (LANDR ~$9-25/master, eMastered subscription) charge for output formats and mastering credits. Ours is unlimited, free, with no watermark.
Everything runs in your browser via the Web Audio API. Your audio never leaves your device.
Output is high-resolution WAV, ready for upload to any distributor (DistroKid, TuneCore, CD Baby, Bandcamp).

Frequently Asked Questions
What is audio mastering?
Audio mastering is the final step in music production. It optimizes your mix for playback across all systems — applying EQ, compression, stereo enhancement, and loudness normalization to create a polished, professional-sounding track.
Is this mastering tool really free?
Yes, 100% free. There's no signup, no trial, and no premium tier. You can master unlimited tracks with all five presets at no cost.
How do I choose the right preset?
Try each preset and use the A/B comparison to hear the difference. Balanced works for most genres, Warm suits acoustic/jazz, Bright is great for pop/electronic, Punchy adds energy to hip-hop/rock, and Loud maximizes volume for EDM/trap.
What formats are supported?
Upload MP3, WAV, OGG, FLAC, or M4A files. The mastered output downloads as high-quality WAV format, preserving full audio fidelity.
Will mastering fix a bad mix?
Mastering enhances a good mix but can't fix fundamental issues like clipping, phase problems, or poor frequency balance. For best results, make sure your mix is well-balanced before mastering.
Can I master songs for Spotify or Apple Music?
Yes. Our mastering presets produce output that meets streaming platform loudness standards (around -14 LUFS for Spotify). The WAV output is ready to upload to any distributor.
Does it work on mobile?
Yes. The AI mastering tool runs in any modern mobile browser. Upload your track, choose a preset, preview, and download — all from your phone or tablet.
What target loudness should I master to?
For streaming, aim around -14 LUFS integrated. Spotify, YouTube and Amazon Music normalize to -14 LUFS, Apple Music to -16 LUFS, Tidal to -14 LUFS. Mastering louder than -9 LUFS will get turned down by streaming normalization and can trigger audible distortion.
How is this different from LANDR or eMastered?
RemoveVocals AI Mastering is completely free with no watermarks, no signup and no export limits. LANDR charges around $9-25 per master and eMastered is subscription-based. Our tool gives you 5 presets, real-time A/B comparison and high-resolution WAV export for free.
Can I master a podcast or spoken word with it?
Yes, though podcast loudness targets are different (-16 LUFS mono / -19 LUFS stereo). The Balanced preset works well for spoken word. For heavy voice processing use our Noise Reducer and Equalizer tools beforehand.
Are my files uploaded anywhere?
No. All processing runs directly in your browser using the Web Audio API. Your audio never leaves your device, nothing is stored on our servers, and no account is required.
Can I use mastered tracks commercially?
Yes. You own the output. Use your masters commercially, release them on any streaming platform, sell them on Bandcamp, or license them — there are no watermarks and no usage restrictions from RemoveVocals.
