Mastering & Distribution Services
4 tools · 2 free or freemium
Mastering and distribution are the last two technical steps between a finished mix and a release the public can actually hear, mastering polishes what’s already there, distribution gets it onto the platforms people use to listen.
It’s for independent artists releasing without a label handling the technical side, and anyone self-releasing to Spotify, Apple Music, or Bandcamp who needs the final version to sound finished and actually show up where listeners are.
Chance the Rapper is the clearest proof that this path can go all the way. He gave away “Coloring Book” for free, streaming-only, with no traditional label distribution deal behind it at all. In 2017 it won Best Rap Album at the Grammys, the first streaming-exclusive project in history to take home a major Grammy award. A record built entirely outside the traditional label and physical-distribution system had just beaten albums that weren’t.
Browse this category if the mix is finished and the only thing left is making it sound as good as the final release deserves, and making sure people can actually find it.

LANDR
SubscriptionLANDR combines automated mastering and digital distribution for independent musicians and producers. Upload a finished mix, compare mastering options and prepare a release for streaming services. Its Studio subscription bundles these services with samples, plugins, collaboration tools and music courses. From mix to release The online mastering service analyses an uploaded track and creates a processed version you can preview. Try different styles and loudness settings, then use volume matching to compare the master against the original without simply favouring the louder version. - Use reference mastering to guide the result with another recording. - Master an album or EP together for consistency across tracks. - Download MP3, WAV or HD WAV masters according to your purchase or subscription tier. - Submit singles, EPs and albums through LANDR Distribution, with release setup, royalty splits, streaming statistics and promotional links. - Browse royalty-free samples and instrument or effects plugins through the wider LANDR catalogue. - Share music for feedback and use Sessions to stream DAW audio during remote production calls. Distribution is a separate release process. A mastered file still needs artwork, metadata and the rights required for the recording and any samples or cover song. Browser, mobile or inside your DAW Online mastering runs in a browser. LANDR also offers iOS and Android apps for uploading tracks, previewing masters and accessing the synced library. The LANDR Mastering Plugin processes audio inside a compatible DAW. It supports VST3, AU and AAX on macOS, and VST3 and AAX on 64-bit Windows. Apple Silicon and Intel Macs are supported. Check the plugin's current system requirements and your host before buying. Other plugins in a Studio bundle have their own compatibility requirements. Plans and buying considerations LANDR Studio is a recurring subscription with Essentials, Standard and Pro tiers. The mastering format allowance and plugin edition vary by tier. Essentials includes MP3 mastering, while Standard and Pro add WAV and HD WAV downloads. Standard includes Mastering Plugin SE and Pro includes Mastering Plugin Pro. Compare the current sample allowance, included plugins and distribution terms before choosing. Free online mastering previews let you assess a track, but downloading a full master requires a purchase or paid plan. Individual online masters can be bought separately, and the mastering plugin also has a perpetual licence option. A free account or temporary trial does not provide the full Studio subscription.

Its reference-track workflow suits producers who want to guide a master toward another recording without buying a wider production bundle. - DistroKid is an alternative for distributing finished releases, with unlimited uploads and royalty splits on its subscription plans. Compare it when distribution is the main job and you already have mastering covered.
DistroKid
SubscriptionA distribution service that uploads music to streaming platforms and handles royalty collection. It’s used when you’re ready to release tracks and want a straightforward way to get them onto Spotify, Apple Music, and similar platforms.
SoundBoost
FreemiumSoundBoost is an online AI mastering service for musicians who want to finish a mix without building a conventional mastering chain. Upload a track, choose an AI engineer, or type plain instructions such as "warmer, less harsh, keep the dynamics." The service analyses genre, tempo, loudness, and the mix itself, then assembles a chain using EQ, compression, saturation, stereo control, resonance treatment, and true-peak limiting. Every prompt becomes a separate revision. You can compare it against the original and keep the version that works. Reference mastering can use a Spotify track to guide loudness, width, and tonal balance. The knobs are still there for people who would rather adjust the sound themselves. SoundBoost runs in a browser and has iOS and Android apps, with projects synced across devices. Its free mastering account is useful for testing, but there is a catch: you can upload, make up to ten revisions per project, use the controls, and hear 30-second previews, but you cannot finalize or download the full master. Paid Unlimited plans add reference mastering, mobile premium access, full-song finalizing, and 24-bit WAV or 320 kbps MP3 downloads. Unlimited Plus removes the revision cap and adds full-length previews, bulk mastering for up to ten tracks, and priority rendering. The public pricing page currently advertises annual Unlimited pricing from $4 per month. Weekly and monthly billing are also available, so check the live page before buying. The stem splitter is more generous than the mastering free tier. Standard five-stem separation and the browser practice studio are free with unlimited uploads, giving vocals, drums, bass, other, and a generated metronome. You can loop sections, change tempo or key, read detected chords and synced lyrics, and use a limited rolling allowance for MP3 stem downloads. Paid members get HD WAV and mix exports, Hi-Fi processing, and dedicated guitar and piano stems. SoundBoost also sells a separate AI music-video service that builds an editable storyboard before rendering a film cut to the track. A free account can create limited 30-second storyboard previews, but full videos use their own subscription and credit system. A mastering membership does not pay for them. Finished films can reach 1080p MP4, and paid plans include a creator pack with the clean cut, clips, stills, stems, lyrics, and an editor timeline. The company says uploaded audio is stored in the cloud, processed by its own hosted models, and not used to train those models. Prompt text and current mastering settings go to OpenAI. Video directions, lyrics, and reference images can be sent to OpenAI, Anthropic, and fal.ai. The privacy policy says the original song audio is not sent to OpenAI or Anthropic. Your tracks and masters remain yours for commercial use. Projects can be deleted. SoundBoost is a strong fit for independent artists who want fast iterations, stem practice, and mobile review. An experienced mastering engineer can still catch mix problems that a one-minute render may miss.
Calrogk Online Mastering
FreemiumCalrogk Online Mastering is a browser-based tool for preparing finished mixes with mastering profiles, manual controls and WAV or MP3 export. Single-track mastering works without an account, and Calrogk says the audio is processed on your device rather than uploaded to a server. Shape a finished mix Load a track, compare seven suggested profiles, then adjust the result before downloading. The tool is aimed at musicians preparing their own releases, including songs made with AI music generators. You can start with a profile and fine-tune it instead of accepting one fixed output. - Adjust tonal balance with a six-band EQ. - Change compression, transient punch and stereo width. - Fold bass to mono and set loudness and limiter controls. - Switch between the original and mastered versions for comparison. - Trim silence and add a fade-out before export. - Download a WAV or MP3 master. Files and browser setup The file picker accepts MP3, WAV, M4A, AAC, FLAC and OGG. Processing uses the browser's Web Audio API, so file decoding and performance depend on the browser and device. Calrogk also offers an installable web-app shortcut that opens the tool in its own window. Free and Premium features Single songs can be mastered one at a time for free, without registration. The free site displays advertising. Premium removes ads and adds album processing with matched loudness, 32-bit float WAV export, project saving and additional processing controls. Premium is available through monthly or annual subscriptions, or a one-time purchase. Before exporting Compare at similar playback levels so a louder result does not obscure changes to the mix. Check the exported file against your intended delivery requirements. Calrogk also offers processing for artifacts in AI-generated audio, but its effectiveness depends on the recording and has not been independently tested for this listing. Alternatives to Calrogk Online Mastering - LANDR offers online mastering with reference-track and album workflows. Consider it when you want to guide a master with another recording. Master downloads require payment. - BandLab offers a separate mastering tool with four free presets. It is another option for comparing preset-based masters, particularly if you already use BandLab for recording and sharing music.
What to look for in a Mastering & Distribution
- What mastering actually changes
- Mastering isn't a second mix, it's a final polish pass, loudness, tonal balance, and consistency across a release, applied after the mix is already finished. If it's fixing balance problems, that's a mixing issue, not a mastering one.
- One-time fee or annual subscription
- Distribution pricing varies between per-release payment and a yearly fee covering unlimited uploads. Which one is cheaper depends entirely on how often you actually release music.
- Who keeps what percentage
- Some distributors take a cut of royalties in exchange for no upfront fee. Others charge a flat rate and let you keep everything earned. Read this carefully before uploading anything.
- How fast it needs to move
- Automated mastering and instant distribution get a release live quickly. A human mastering engineer takes longer but can catch things software still misses on unusual material.
Frequently asked questions
- Can a fully independent release actually compete without a label?
- Chance the Rapper's "Coloring Book" is the clearest proof it can. Released free, streaming-only, with no traditional label deal at all, it won Best Rap Album at the 2017 Grammys, the first streaming-exclusive project ever to do so.
- Do I need professional mastering, or can I skip straight to distribution?
- Technically you can distribute an unmastered mix, but it will likely sound noticeably quieter or less polished next to mastered releases on the same platform. Mastering is a small step that closes a real, audible gap.
- How long does distribution actually take to go live?
- Most digital distributors deliver to major platforms within a few days to two weeks, though some allow scheduling a specific release date in advance. Physical distribution, where it still exists, takes considerably longer.
- Do I lose the rights to my music by using a distributor?
- Reputable distributors don't take ownership of your masters, they're a delivery service to streaming platforms, not a label. Read the specific terms of any service before uploading, since royalty splits and rights vary by provider.
