Uploading Tracks

A track is a complete song or composition. You can optionally include stems (the individual parts of your production) alongside your track.

  1. Choose “Track” from the upload type selector.

  2. Add your audio file. Drag and drop or click to browse. Supported formats: WAV, FLAC, MP3, AAC, OGG, AIFF. Maximum file size: 500MB. If you upload a large WAV file, FreeMix compresses it to FLAC automatically — this is lossless (no quality loss) and can reduce upload time dramatically (e.g., a 920MB WAV becomes a 262MB FLAC).

  3. Add cover art (optional). Upload a JPG, PNG, or WebP image (max 10MB, max 3000x3000px). If you don’t add art, FreeMix generates a unique placeholder based on your track.

  4. Fill in metadata. FreeMix auto-detects what it can from your file:

    • Title — auto-populated from filename or embedded metadata; edit as needed
    • BPM — auto-detected; you can override
    • Key — auto-detected; you can override
    • Genres — select up to 5 from the genre list (100+ genres covering electronic, hip-hop, and more)
    • Tags — add up to 10 freetext tags for discoverability
    • Description — optional notes about the track

  5. Choose a license. Select a tier (FM:Open, FM:Remix, FM:NC, FM:Stems, FM:DJ, FM:Samples) and any modifiers. The license selector explains each option as you go. Not sure which to pick? See Choosing a License.

  6. Add stems (optional). If you want to share the individual elements of your production (drums, bass, vocals, etc.), drop your stem files here. FreeMix auto-detects stem types from filenames (e.g., kick.wav → Kick, bass_synth.wav → Bass Synth). You can upload up to 12 stems per track, each up to 200MB. Stems inherit the BPM from the parent track.

  7. Confirm the upload attestation. Check the box confirming you created this content and have the rights to distribute it on FreeMix.

  8. Review and publish. The review screen shows everything — track info, stems (if any), license, and total upload size. Hit Publish. You’ll see per-file progress with upload speed for each file. Once complete, the published screen shows a summary with compression savings and total upload time.

After Publishing

Section titled “After Publishing”
  • Your track appears on your profile and in the activity feed
  • You can optionally cross-post to Bluesky to share with your followers there
  • You can edit track metadata later (title, description, genres, tags, BPM, key, cover art) — but the license cannot be changed once set
