Master a track

From master to release

Your master is finished. Here’s what comes next.

Your master is only one part of a clean release. Use this short guide to prepare the file, artwork, credits and timing before you send anything to a distributor.

Your audio still stays yours. This guide does not upload or inspect a file.

01

The file

Start with one finished, lossless master.

Send your distributor a WAV or FLAC master, not the MP3 you made for messages or quick listening. Lossless delivery preserves the finished audio before each streaming service creates its own listening formats.

  • Listen to the beginning, middle and end of the exported file.
  • Check that the first sound and final fade are not cut off.
  • Keep the original mix and the final master as separate files.
  • Use a clear file name you can still recognise six months from now.

DistroKid currently accepts WAV and FLAC among several formats, and recommends them for best quality. Always check your chosen distributor's current requirements.

02

The cover

Make artwork that survives a thumbnail.

A cover is often seen at a few centimetres wide. One clear focal point and readable contrast usually travel better than tiny details. Check it at full size and as a small square before submitting.

  • Export a square RGB image; a 3000 × 3000 px JPG is a useful target.
  • Use artwork and photography you have permission to publish.
  • Avoid URLs, QR codes, prices and streaming-service logos.
  • Make sure the artist and release identity match the metadata.
03

The credits

Write the details once, then copy them consistently.

Prepare the information in a note before opening the upload form. Consistent spelling helps stores connect a release to the right artist pages and keeps collaborators properly credited.

Artist identityArtist name and existing profiles

Use the same spelling and styling on every service. Double-check which existing Spotify or Apple Music artist page belongs to you.

Release identityTrack, single, EP or album title

Write the final track order and featured-artist formatting. Avoid changing it casually after submission.

PeopleSongwriters, producers and collaborators

Collect the names and roles now. Upload forms may require a songwriter's real name even when the public artist uses a stage name.

RightsOriginal, cover, sample and explicit status

Do not submit a cover, remix or sample until the necessary permission or licence is clear. Mark explicit content accurately.

04

The date

Give the release room to arrive.

Store processing is not instant or identical everywhere. DistroKid currently recommends uploading about four weeks ahead when you want the same planned release date across services. That also gives you time to pitch, prepare links and correct anything you notice.

05

The delivery service

Choose a distributor that fits how you release.

A distributor sends your audio, artwork and metadata to services such as Spotify and Apple Music. It does not replace mastering, rights clearance or your final review. Compare pricing, supported stores, payout terms and how easy it is to edit or remove a release.

Before submit

The two-minute final check

Uploads are easier to correct before they leave your hands.

  • The lossless master opens and plays to the end
  • Artist, titles and track order are final
  • Credits, explicit status and rights are accurate
  • Artwork is square, clear and licensed
  • Release date leaves enough processing time
  • You kept local copies of every final asset

After delivery

Keep your launch simple.

Save the distributor confirmation, claim or check your artist profiles, and verify the release when it goes live. Share one reliable landing link rather than a different store link in every post. If something is wrong, use the distributor's correction flow before replacing the whole release.
