DAW Import Checklist
Distinguish mixes, stems, MIDI and projects, then check timing, tempo treatment and tails.
Know what the file can preserve
A stereo mix supports cutting, gain changes and spectral processing, but it is not a complete set of independent notes and instruments. Stems provide broader layer control. MIDI contains events that need a sound generator. Project files also depend on software versions, plug-ins and referenced assets. Inventory what you received before choosing an editing method.
Import checklist
| Check | Action | If it fails |
|---|---|---|
| Original | Keep source files and work on copies | Restore or download again |
| Start | Align tracks at the agreed origin, retaining leading silence | Check separate trimming |
| Tempo | Audition the untreated file before enabling time stretching | Undo unnecessary warping |
| Pitch | Compare with a reference or score | Separate project transposition from source pitch |
| Tail | Listen through the complete reverb and delay ending | Extend the export range |
| Dependencies | Collect external assets into the project | Reopen from another location |
Fictional example: an intro arrives late
If an intro is half a second late against picture, compare file placement with the picture marker before speeding up the music. Move the clip if placement is the only issue. For drifting tempo, use a small number of meaningful timing anchors and listen for damage to transients, pitch and texture. If the form itself is unsuitable, return to candidate selection. Keep edited mixes separate from the original files.
Save the project, collect its dependencies and export a reference mix that plays without the generation service. Reopen the local project independently and check that assets do not rely on temporary download links.
