Why us
You upload your mix and hear a cleaner, fuller, more balanced version that feels ready to share.
A more finished sound
Your song comes back tighter, clearer, and more even from intro to outro. That last layer of polish helps the whole mix feel complete instead of sounding like a rough draft.
More confidence to share
A polished master helps vocals, drums, bass, and melody sit together better. You can send your music to friends, post a clip, or keep a personal version that sounds like a real finished song.
Better playback on everyday devices
Your music should still feel solid on phones, earbuds, laptops, and car speakers. A balanced final version makes it easier for the song to hold together when people listen outside your setup.
More songs actually completed
Finishing matters. When the last step feels simple, you spend less time second guessing levels and more time wrapping up demos, trying new versions, and moving on to your next idea.

These topics explain what AI mastering changes, how the tool handles loudness and balance, and what kind of file you can expect before you download and share your song.
Master song online free by uploading one finished stereo mix, previewing the result, and downloading the version that feels right. This works best when your levels, edits, and arrangement are already set, since mastering polishes the whole song rather than rebuilding the mix. If you still need to create the song itself, start with the OnMusic AI song generator first.
AI audio mastering lets you compare a few final feels without reopening the mix. You can test a louder pop finish, a softer lo-fi balance, or a cleaner vocal-forward result and keep the version that fits the song. It is a simple way to hear how small mastering moves change the energy of the same song.
Free AI mastering online lets you polish audio in a browser on a phone or laptop without extra software. It fits demos, podcast intros, and finished songs that need better level and balance before you share them. If the song is not written yet, create one in the music generator first and come back when the mix is ready.
How to master a song online is simple with AI song mastering when the mix is finished: upload the file, preview the change, and listen for steadier loudness, clearer highs, and tighter low end. The tool keeps your arrangement and performance the same while polishing the final sound. If something still feels off, go back to the mix before you export the master.
Mastering can polish a mix, but it will not fix clipping, heavy distortion, or a vocal that sits far above the music. If the balance is off, clean it up first with an AI vocal remover or separate problem parts with an AI stem splitter. Then run mastering on the improved mix so the final file sounds more consistent across speakers and headphones.
Upload one mixed song file, let AI mastering polish loudness and balance, then download a mastered audio file you can play, post, or share.
Start with a finished mix, such as a demo, beat, or full song with vocals. Add your audio file so the tool can work on the whole song as one stereo master.
The tool adjusts overall level, tone, and dynamics so your song feels more even and easier to play on everyday devices. You keep the same performance and arrangement, but the final file sounds cleaner and more controlled.
Listen to the mastered version, then save the finished audio file. You get one polished master of your uploaded song, ready for sharing, posting, or using in your next project.
Use this tool when your song sounds quiet, uneven, or flat and you want a louder, cleaner file for video, posting, or sending to friends.
Bedroom songwriters
Bedroom songwriters use this when their mix sounds quiet, flat, or uneven next to other music. A quick master helps the same song feel fuller and more ready to share with friends, collaborators, or a small release.
Creators using online music mastering AI
Video creators, streamers, and small artists use this to make their music sound more balanced before posting it online. It is a practical fit when you want a cleaner final file for YouTube, TikTok, or a portfolio link.
First-time producers
First-time producers use this to hear what a more polished version of their mix sounds like before they learn deeper mastering moves. It helps when you want a better reference, a cleaner demo, or a simple way to compare before and after.
Features
Upload your mix, shape the final sound, and export a louder, cleaner song that is ready to share.
Instant track mastering for uploaded songs
Upload one finished audio file and the tool checks level, peaks, and tonal balance before applying a full master in one pass. It is made for a completed song or beat, not separate stems, so you can hear a polished version quickly.
AI mix mastering tool with adaptive processing
This AI mix mastering tool adjusts EQ, compression, and limiting based on the file you upload instead of forcing one fixed setting on every song. Busy choruses, softer verses, and vocal-heavy sections can be treated differently so the whole master feels more even.
Loudness mastering online with peak control
Loudness mastering online raises overall level while catching clipping and sharp transients that can make a song feel harsh. You get a louder, cleaner result that is easier to play back on phones, headphones, and laptop speakers.
Tone shaping for vocals and instrumentals
The tool rebalances low end, mids, and highs so muddy bass, boxy mids, or brittle top end do not overpower the song. If you created a beat, an instrumental, or a vocal song, mastering helps the file feel more finished before you share it.
Before and after preview with final export
You can compare the original audio to the mastered version before you download the result. If you want a clean instrumental first, use an AI vocal remover, then bring that file into mastering and export the finished song.
Upload your song, hear a clearer, louder version, and compare it before you download.
Upload your audio, compare the original and the master, then download a cleaner version you can keep or share.
