Pocket Master supports 15. Every track is measured and mastered locally, one at a time.
From master to release
Your master is finished. Here’s what comes next.
Before you send a release to a distributor, check the exported audio and gather your artwork, credits and release details. This guide walks through those steps for a single or a full release.
This is a reading guide. It does not open, inspect or upload your files.
Listen at the master’s export level, then match loudness to compare tone and dynamics.
On the web, prepare the package locally, then save every master and the Master Report with one download.
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.
Saving a web Release: review your masters, choose the format and metadata, then select Prepare ZIP. Changed files are rebuilt one at a time. When preparation finishes, select Save ZIP and check your browser’s downloads. Extract the ZIP before submitting its audio files to a distributor.
Large releases use your browser’s private local file storage when available. Keep free space for the masters and ZIP, and save before reloading, closing the tab or starting another release. Audio never uploads. Without writable local file storage, a release is limited to 256 MiB; one ZIP must stay below 4 GB. See the full batch workflow.
- 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
Check your cover at a small size.
A cover is often seen at a few centimetres wide. A simple composition and clear contrast are easier to recognise 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.
Use the same spelling and styling on every service. Double-check which existing Spotify or Apple Music artist page belongs to you.
Write the final track order and featured-artist formatting. Avoid changing it casually after submission.
Collect the names and roles now. Upload forms may require a songwriter's real name even when the public artist uses a stage name.
Do not submit a cover, remix or sample until the necessary permission or licence is clear. Mark explicit content accurately.
04
The date
Allow time for store processing.
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.

After delivery
Check the release when it goes live.
