AI Song Mastering for
Suno, Udio, and Creators

1 ✨

Built for Modern AI Music

Our AI mastering engine is tuned for Suno, Udio, and Stable Audio. We re-balance the frequency spectrum and add the "commercial polish" your raw AI music is missing.

2 ⚡

Zero Waiting. Batch Processing.

Master entire albums in seconds. Our offline processing runs 100% in your browser. No server uploads, no privacy risks, and unlimited simultaneous tracks.

3 🔒

Best Free LANDR Alternative

Tired of subscriptions? We provide professional AI song mastering - high-pass filters, bus compression, and brickwall limiting - absolutely free. No account, no credit card.

Why does AI music sound bad without mastering?

AI-generated music often sounds "thin" or "quiet" compared to professional tracks. Spotify and YouTube normalize audio to -14 LUFS. We hit those targets perfectly every time.

Common Questions

Is it really free?

Yes. 100% free with no account, no watermarks, and no file limits. All processing runs 100% in your browser using the Web Audio API.

Do I need an account?

No. We built this to be the fastest tool online. Just drop your file and download your master. No email address or registration required.

Optimal settings for YouTube?

YouTube normalizes audio to -14 LUFS. Our brickwall limiter is calibrated to hit these streaming targets automatically.

Does it work with Udio/Suno?

Absolutely. It is specifically optimized to fix the common audio quality issues found in AI-generated music exports from Suno and Udio.

Is this an AI mastering plugin like Ozone or LANDR?

Unlike a heavy AI mastering plugin (like Ozone) or a paid subscription service (like LANDR AI mastering), our tool runs entirely in your browser. You get professional AI song mastering results online for free, without downloading any software or paying for LANDR mastering credits.

Pro Tips for Mastering Suno AI Tracks

10 expert techniques to get professional, streaming-ready sound from your Suno exports.

01

Always Export WAV from Suno

Suno's WAV export is lossless — it gives the mastering engine the most audio data to work with. MP3s introduce compression artifacts that can't be reversed. Always use WAV for the cleanest master.

02

Set Intensity Between 70–80 for Streaming

Spotify and YouTube normalize to -14 LUFS. An Intensity of 70–80 hits this target perfectly without over-compressing. Going above 90 will start to sound distorted and "crushed."

03

Use "Brighter" EQ for Electronic & Pop Suno Tracks

Suno's electronic and pop generations often have a slightly dull high end. Slide EQ toward Brighter by 2–4 points to add presence, air, and clarity to the top end without harshness.

04

Use "Warmer" EQ for Suno Hip-Hop & Lo-Fi

For Suno's hip-hop, R&B, and lo-fi beats, sliding toward Warmer boosts the low-mids giving the track a fuller, more vintage and rounder sound that fits the genre.

05

A/B Compare Every 30 Seconds

Use the Mastered / Original toggle constantly while adjusting sliders. Your ears adapt quickly — switching back to the original every 30 seconds keeps your reference fresh and prevents over-processing.

06

Master Your Full Suno Album Together

Upload all tracks from an album at once and use the same Intensity and EQ settings across all of them. This keeps loudness and tone consistent so the album flows cohesively when played on streaming platforms.

07

Lower Intensity for Suno Acoustic & Orchestral

For Suno's acoustic, classical, or orchestral tracks, set Intensity lower (50–65). These genres need natural dynamic range — heavy limiting kills the emotional impact of quiet-to-loud moments.

08

Seek Forward to Check the Drop

Click the waveform to jump to the loudest section of your Suno track (usually the drop or chorus) and listen there first. This is where clipping and distortion from over-limiting are most likely to appear.

09

Download as ZIP for Distrokid & TuneCore

Use DOWNLOAD FULL MASTERING ALBUM to get all your Suno tracks in a single ZIP. Each file is prefixed MASTERING_ — organized and ready to upload directly to Distrokid, TuneCore, or CD Baby.

10

Your Audio Never Leaves Your Computer

Unlike LANDR or eMastered, all processing runs 100% in your browser. Your Suno tracks are never uploaded to any server — so your unreleased music stays completely private until you choose to release it.
