Essential guidelines for organizing and preparing your multitrack files for professional mixing.
A clean mix starts with clean files.
To ensure the best possible result when sending your project for mixing, it's important that everything is well-organized, properly labeled, and exported in a format that gives the mixing engineer full flexibility. Below you'll find a detailed checklist and explanations to help you prepare your session for mixing. If any questions should arise, feel free to get a hold of me either via mail or phone.
Every audio file should start from bar 1 (or 00:00:00) — even if the actual sound comes in later. This ensures that when all the files are imported into a new session, everything lines up perfectly.
Good example:
A vocal harmony that only plays in the chorus is still exported as a full-length file, starting at bar 1.
Bad example:
A vocal harmony stem that starts exactly when the part comes in. This will cause alignment issues.
Tip: Most DAWs have a “consolidate” or “bounce in place” feature for this.
Use clear, descriptive names for each stem. This saves time and avoids confusion for the mix engineer.
Recommended format:
Instrument_Role_Position
Examples:
Avoid default names like Audio_01.wav or Track5.wav.
Unless a specific effect is absolutely essential to the sound or the vibe (for example, a chorus on a synth or a creative vocal delay), export your tracks dry:
If you’re unsure whether an effect should be kept or removed, you can send both a dry and a wet version, clearly labeled (e.g. LeadVox_Main_Dry.wav and LeadVox_Main_Wet.wav).
Lossy files like MP3 reduce audio quality and can negatively affect the final mix.
Let your mix engineer know the BPM (tempo) of the track. If your song includes tempo changes, export and include a tempo map or a MIDI file with tempo automation.
Example:
“The track is in 6/8 at 90 BPM throughout.”
Always include a rough mix of your track — even if it's not polished. This gives your engineer an idea of:
Label it clearly, for example: TrackName_RoughMix.wav.
If there are parts that need special attention (or things you're unsure about), include a short text file or an email with notes such as:
More context always leads to a better result.
Don’t send full DAW projects unless requested. Engineers often work in a different DAW than you, so audio files (WAVs) are the universal standard.
Example folder structure:

│ ├── LeadVox_Doubles.wav
│ ├── Guitar_RhythmL.wav
