Preparing Stems for a Mix Engineer

Sending stems to a mix engineer should be seamless. Poorly labeled, inconsistent, or improperly exported stems waste everyone is time and money. This guide ensures your stems arrive ready to mix on the first try.

Step-by-Step Guide

Consolidate All Tracks from Bar 1

Select all regions and consolidate (bounce in place) from the very beginning of the session. Every stem must start at the same point so they line up perfectly when imported.

Remove All Processing (Unless Discussed)

Remove EQ, compression, and effects from individual tracks unless the engineer says to keep them. Leave creative effects (like a vocoder or intentional distortion) that are part of the sound.

Name Every File Clearly

Use a consistent format: 01_Kick.wav, 02_Snare.wav, 03_Bass_DI.wav, 04_LeadVocal.wav. Number them in the order they appear in your session. No spaces in filenames — use underscores.

Export at Session Sample Rate, 24-Bit WAV

Export every stem at the same sample rate and bit depth. WAV format, 24-bit minimum. Never export stems as MP3 or at mismatched sample rates.

Verify Stems Sum to the Original Mix

Import all your exported stems back into an empty session. Play them together — they should sound identical to your original mix. If something is missing or doubled, fix it before sending.

Include a Reference Mix and Notes

Add a stereo rough mix file so the engineer knows your vision. Include a text file with BPM, key, any notes about the song, and what you want the mix to sound like.

Pro Tips

Group related tracks into stem groups if the engineer requests it — for example, all drum mics into one Drums_Stem.wav.
If you have multiple vocal takes comped together, make sure the comp is committed before exporting. Do not send 15 vocal takes and expect the engineer to sort them out.
Zip the folder and upload to a reliable service like Google Drive, Dropbox, or WeTransfer. Avoid email attachments.
Include alternate takes only if asked — otherwise they just add confusion.

Common Mistakes

Stems Not Starting at the Same Point

If stems start at different times, they will not line up. Always consolidate from bar 1, beat 1 so every file has the same starting point.

Vague or Missing File Names

Files named Audio_01.wav or Track 23.wav are useless. The engineer has to guess what each file is. Clear naming saves hours.

Leaving Master Bus Effects on Stems

If you have a limiter or EQ on the master bus, it gets printed on every stem. Bypass master bus processing before exporting stems.

Exporting at Different Sample Rates

Mixing sample rates causes pitch and timing problems. Verify every stem is the same sample rate before sending.

Frequently Asked Questions

Stems are grouped submixes (e.g., all drums into one file). Multitracks are individual tracks (kick, snare, hi-hat each as a separate file). Most engineers want multitracks.

Generally no — the mix engineer will add their own. If a specific effect is integral to the song, print it as a separate stem so the engineer can blend it.

WAV, 24-bit, at your session sample rate (usually 44.1 or 48 kHz). Never MP3. AIFF is also acceptable.
