How to send music stems, multitracks and masters

3 min read · Updated 2026-11-13

Short answer

Put stems and masters in clearly named folders, upload them to Pandafile and share the link. Your collaborator can download single tracks or everything as one ZIP.

A single song can easily mean 30 or 40 WAV stems at 24-bit, plus several masters. Streaming links and chat apps often compress audio. Pandafile sends the exact files you upload, byte for byte, so nothing is lost on the way to your mixer, mastering engineer or label.

Prepare your session

  • Bounce every stem from the same start point so they line up in any DAW.
  • Name tracks clearly, for example 01_Kick.wav, 02_Snare.wav, 10_Vox_Lead.wav.
  • Put stems in a Stems folder and masters in a Masters folder, with sample rate and bit depth in the master file names.
  • Add a short text file with the tempo, key and any notes.

Send it

  1. Open pandafile.co and use Choose a folder to add the whole song folder.
  2. Choose Send by email to send to your mixer or label, or Get a link if you want to paste it into a chat.
  3. Add a title such as the song name and version, plus a short message.
  4. Send. With email sends you will be told when each recipient downloads.
