The difference between a smooth mix session and a frustrating one often comes down to stem preparation. Before exporting, confirm whether the engineer needs individual tracks or grouped stems. Give each file a clear name and export from the same agreed starting point so the files can be aligned in another session.
Format and references
Keep the delivery sample rate consistent with the session and confirm the required format before exporting. If the project uses sources recorded at different rates, check how the DAW converts them for the delivery. Include a reference mix and notes explaining the balance, space and energy you want to preserve.
What to keep and what to remove
Remove files that are not part of the arrangement. Keep processing that defines the sound and identify it in your notes. When useful, provide an additional version without that processing. Agree with the engineer which mix-bus or master-bus processes should remain in the delivery; do not remove an intentional sound simply because it is on a bus. A limited reference can help communicate the production intent even when a separate working version is needed.
Check the export before sending
Import the files into an empty session and check alignment, duration, names and missing parts. Preserve the space needed for the first attacks and effect tails. Add the tempo and any production notes. This check helps the next session focus on musical decisions instead of reconstructing the arrangement.
