Use a common start point
Export every stem from the same timeline position, even when an instrument enters later. This lets the engineer import the files and align them without guesswork.
Confirm the requested sample rate, bit depth and file format with the engineer. Avoid changing settings at the last minute without checking compatibility.
Label tracks clearly
Use names such as Kick, Snare, 808, Lead Melody and Vocal Effects rather than generic labels like Audio 17. Group related tracks when the recipient has requested grouped stems.
Include tempo and key if known, along with notes about sidechain, special effects or sounds that are essential to the production. Do not assume the engineer will infer every creative intention.
Clarify processing and references
Ask whether the engineer wants processed stems, dry versions or both. Print effects when they are integral to the sound, and provide alternatives when requested.
Include a reference bounce and check that the stems sum to a mix reasonably close to the intended version. Keep a copy of the exact delivery folder for future revisions.
