Mastering options and help
What AI mastering is designed to fix
AI exports can contain brittle highs, softened transients, low-mid buildup, uneven sections, and synthetic vocal texture. A loudness-only pass may preserve or exaggerate those issues, so Planetary checks tone, dynamics, peaks, stereo translation, and vocal balance before delivery.
Tame harsh, fizzy highs
Dynamic tone shaping reduces brittle top-end energy while preserving useful air and detail.
Clear mud and tighten lows
Low-mid buildup is controlled and bass focus is checked across small and full-range playback.
Recover transient punch
Transient shaping can help drums and plucks read more clearly when generation has softened their attack.
Balance uneven sections
Section-to-section level changes are managed without treating every moment as equally loud.
Check stereo translation
Width and depth are adjusted with mono compatibility and common playback systems in mind.
Reduce vocal artifacts
De-essing and targeted processing can soften synthetic sheen without promising to erase source artifacts.
Ultra hears what Standard cannot
Standard shapes the stereo mix as one signal. Ultra first separates voice and music, processes them separately, and recombines them into one finished master. That extra control helps when vocal harshness or masking needs different treatment from the backing track.
Why it sounds cleaner: a fix for the vocal no longer has to touch the drums, bass or cymbals. A fix for the music no longer has to squash the voice.
- Cleaner vocals without dulling the beat
- Tighter music without crushing the voice
- Less mud and fewer cross-effects
- One recombined, release-ready master
| Feature | Standard | Ultra |
|---|---|---|
| Processing | One pass over the full stereo mix | Voice and music cleaned separately, then recombined |
| Best for | Balanced mixes that need cohesive finishing | Mixes where voice and backing need different treatment |
| Delivery | One complete 24-bit WAV | One complete 24-bit WAV (recombined master) |

How it works
Upload the finished mix
Use MP3, WAV, FLAC, or M4A. The mastering chain evaluates the whole song, not a sample of it.
Hear your free preview
Standard masters the whole song for free. Compare 45 seconds of your mix before and after on your result page.
Download or go Ultra
Download the complete 24-bit WAV for $7.00, or choose Ultra for $10.00 to have voice and music treated separately. Only your account can access the job status and files. Download within the 7-day download window; after it ends, the original upload and mastered files are removed.
Suno mastering loudness reference
Playback normalization is useful context, not a universal upload requirement or a recipe for every song.
Published loudness and delivery references
First-party platform references, checked August 19, 2026. Playback normalization and special delivery programs are context, not upload requirements; platform modes and policies can change.

|---|---|
| Spotify | -14 dB LUFS normal playbackSpotify recommends ≤ -1 dBTP; use ≤ -2 dBTP when mastering louder than -14 LUFS |
| Apple Digital Masters | No universal LUFS targetApple Digital Masters is a special high-resolution delivery workflow, not a general Apple Music loudness target |
| YouTube | No published LUFS upload targetYouTube's official upload specification defines codecs, sample rate, and bitrates rather than a loudness number |
Questions
How much does AI music mastering cost?+
A Standard preview is free. Downloading the complete Standard 24-bit WAV costs $7.00; Ultra costs $10.00. Each payment covers one track. There is no mastering subscription.
What is Suno mastering?+
Planetary Records AI Music Mastering is an online finishing service for AI-generated tracks from Suno, Udio, Riffusion, or a DAW export. It shapes tone, dynamics, stereo image, and peaks across the complete song, then returns one downloadable 24-bit WAV. Standard treats the stereo mix as one signal; Ultra separates voice and music first.
Does this work on tracks I did not make with Suno?+
Yes. The chain accepts any exported mix — Suno, Udio, Riffusion, another generator, or a DAW bounce. Processing targets the artifacts AI exports commonly carry, and those corrections stay conservative enough to leave a conventionally recorded mix intact.
What is the difference between Standard and Ultra?+
Standard shapes the stereo mix as one signal. Ultra first separates voice and music, processes them separately, and recombines them into one finished master. That extra control helps when vocal harshness or masking needs different treatment from the backing track.
What do you need from me?+
Sign in or create a Planetary account, then upload your own finished stereo mix. WAV is best; MP3, FLAC, and M4A are also accepted.
Can I hear it before I pay?+
Yes, in Standard. Sign in and upload your mix, and the whole song is mastered for free. Compare 45 seconds before and after, then download the complete 24-bit WAV for $7.00 if you like it. You can request up to 3 free previews a day. Ultra is paid before processing.
How long does it take?+
Processing time depends on the queue and track length. You can leave after submission and return from My items. We email you when a free preview is ready; for paid masters, artists who opt into email updates also receive a ready link.
What do I get?+
Both modes return one complete 24-bit WAV. Standard shapes the stereo mix as one signal. Ultra first separates voice and music, processes them separately, and recombines them into one finished master. That extra control helps when vocal harshness or masking needs different treatment from the backing track. Only your account can access the job status and files. Download within the 7-day download window; after it ends, the original upload and mastered files are removed.
What can mastering not fix?+
Mastering cannot guarantee complete removal of generated artifacts, repair a broken arrangement or clipped source, force one LUFS reading, or guarantee distributor acceptance. Use artifact reduction first when synthetic fizz, warble, or harsh resonances are the main problem.
What loudness should a Suno track be for streaming?+
Streaming platforms do not publish one shared upload target. Spotify documents playback normalization around -14 LUFS together with true-peak guidance. Apple Digital Masters is a high-resolution delivery workflow, not a universal Apple Music LUFS target. YouTube publishes codec, sample-rate, and bitrate upload specifications but no official LUFS upload target. Treat platform references as playback and delivery context, not guarantees; the right level still depends on the song.
