How to Upload Audio

Accepted formats, how to upload several tracks at once, and what happens if you need to replace a file after submitting it for review.

Where Do You Upload Audio?

In Quick Creation, you upload audio directly in Step 2 of the wizard. In advanced mode, it's uploaded from the Tracks section inside the release's edit page, once the release's general information has been saved.

Accepted Formats

When uploading audio for the first time, the platform only accepts WAV or FLAC — MP3 and other compressed formats aren't accepted at this step, to make sure the highest possible quality gets distributed.

There's no file size limit specifically defined for this upload — beyond that, keep in mind very large files will simply take longer to upload depending on your connection.

Uploading Several Files at Once (Advanced Mode)

From the Tracks section, the "Upload New" action lets you select several audio files at once (up to 99). Each file uploads one after another (not in parallel, so it doesn't overload your connection) and automatically becomes its own track, numbered in the order you uploaded them. You can reorder tracks afterward by dragging them in the table.

What Happens Automatically When You Upload a File

For each file you upload, the platform:

Creates the track in draft status, using the file name as its initial title (you can change it later).
Automatically copies the release's genre, language, and artists/roles onto the new track.
Analyzes the audio to extract duration, format, bitrate, sample rate, and file size — this information is purely descriptive; if the analysis fails for any reason, the track is still created, just without those fields filled in.

Adding a Track You Already Have

If the audio already exists as a track on another one of your releases, you don't need to upload it again: use the "Add Existing" action to link it to this release directly from your catalog.

Highlight Time (for TikTok, Reels, and Shorts)

An optional field marking the most engaging moment of the track.

In Quick Creation, you set it in the same step where you upload the audio, by entering a minute and second.
In advanced mode, it's set afterward by opening the track directly: you choose from a list of options that always leaves at least 30 seconds before the end of the track, to make sure the highlighted clip has enough room.

Replacing or Editing Audio After Uploading

You can replace a track's audio file by opening it directly (the "Edit" action, which opens in a new tab). What you're allowed to do depends on the release's status:

While the release is in draft, in review, or requires changes, you can replace the audio freely.
If the release has already passed quality control or is in distribution, replacing the audio automatically moves it back to "In Review" status — both the track and the entire release — so the team can validate it again before moving forward.
Once a release has been taken down, its audio can no longer be edited.

What the System Doesn't Automatically Validate

The platform extracts metadata from the file, but it doesn't reject audio based on quality: it doesn't check sample rate, minimum duration, whether it's mono or stereo, or detect silence or distortion. Uploading a good-quality master is your responsibility — as a general best practice, WAV or FLAC, uncompressed, 16-bit/44.1kHz or higher is recommended.

When You Can No Longer Upload or Modify Tracks

Once a release moves into quality control, distribution, or later stages, the Tracks section becomes read-only (you'll see a "Tracks are read-only" notice) until it returns to an editable state.
