How to Prepare Your Tracks for Mixing: The Complete Stem Prep Guide

I have mixed thousands of songs over the past 15 years. The single biggest factor in how good the final mix sounds — besides the song itself — is how well the stems were prepared before they hit my inbox. Bad stem prep doesn't just slow me down. It actively limits what I can do with your music.

This is the exact checklist I send to every artist before they submit files to Freshly Baked Studios. Whether you're sending tracks to me or any other mixing engineer, following these steps will get you a better mix, fewer revision rounds, and a faster turnaround.

What Are Stems and Why Do They Matter?

Stems are the individual audio files that make up your song — kick, snare, bass, guitars, vocals, synths, effects, and so on. When you prepare tracks for mixing, you're exporting each element as its own separate file so the mixing engineer has full control over every piece of the arrangement.

This is different from a stereo bounce. If you send me a single stereo file, I can master it, but I can't mix it. Mixing requires access to every individual track.

The Stem Prep Checklist

1. Export as WAV, 24-bit minimum

Always export your stems as WAV files. Not MP3, not AAC, not OGG. WAV preserves the full audio quality without compression artifacts. Use 24-bit depth at whatever sample rate your session is running — 44.1kHz, 48kHz, 88.2kHz, or 96kHz. Don't convert the sample rate during export. If you recorded at 48kHz, export at 48kHz. I'll handle any conversion needed on my end.

32-bit float is also fine if your DAW defaults to it. Just don't downsample to 16-bit — that's for the final master, not for stems.

2. Consolidate everything from the same start point

This is the most common mistake I see. Every single stem needs to start at the exact same point — bar 1, beat 1 of your session. When I drag all your files into my session, they need to line up perfectly without any manual alignment.

In Logic Pro, use "Export All Tracks as Audio Files" and make sure "Include Audio Tail" is checked. In Ableton Live, select all clips, right-click, and "Consolidate" first, then export. In Pro Tools, select all and "Consolidate Clip" from the Edit menu, then bounce each track. In FL Studio, go to File > Export > WAV and check "Split mixer tracks."

If your stems don't start from the same point, the entire mix will be out of sync. I'll have to spend time manually aligning everything, which eats into the time I could spend actually making your song sound incredible.

3. Leave headroom — aim for peaks around -6dB to -3dB

Don't slam your faders to 0dB. If individual tracks are clipping before I even touch them, I'm starting from a compromised position. Pull your faders down so the loudest peaks on each stem sit somewhere between -6dB and -3dB. This gives me room to work without digital distortion.

The overall level of your rough mix doesn't matter. Loudness is my job during mixing. Your job is to make sure nothing is clipping.

4. Remove master bus processing

This is critical. Before you export, bypass or remove everything on your master bus — compressors, limiters, EQ, saturation, stereo wideners, all of it. Those effects are baked into every single stem when you export, and I can't undo them.

The one exception: if a specific master bus effect is absolutely essential to the creative vision of the song and you cannot imagine the track without it, leave it on but also export a version without it. Send me both and tell me in your notes.

5. Name your files clearly

I shouldn't have to guess what "Audio_14_bounce_FINAL_v3.wav" is. Use descriptive names:

• Lead_Vocal.wav
• BGV_Chorus_Stack_1.wav
• Kick.wav
• Snare_Top.wav
• Bass_DI.wav
• Electric_Guitar_L.wav
• Synth_Pad_Verse.wav

If you have multiple takes or layers, number them logically. Group related files with a common prefix — all drum files start with "Drum_" or "Kit_", all vocals start with "Vox_" or "Vocal_". This sounds like a small thing, but on a session with 80+ stems, clear naming saves a massive amount of setup time.

6. Decide what to do with your plugins

Here's where artists get confused. The general rule:

Remove time-based effects (reverb, delay, chorus) unless they're a defining part of the sound. I'll add reverb and delay during mixing to place your tracks in a cohesive space. If you leave your reverb on, I'm stuck with your reverb settings even if they don't serve the final mix.

Keep creative effects that are part of the sound design — heavy distortion on a synth, a specific vocal effect, a guitar amp sim. If it's not an effect but the actual sound, leave it.

Keep or provide both — when in doubt, export two versions: one dry (no effects) and one wet (with effects). Label them clearly. This gives me options.

7. Include a rough mix

Always include a stereo bounce of your rough mix. This is my reference for what you're hearing in your head. It tells me the vibe you're going for, the balance you like, and any creative choices you've made. Without it, I'm guessing.

8. Send notes

A short text file or email with notes makes a huge difference. Tell me:

• What you want the mix to feel like (references help — "I want the vocal to sit like it does on X song")
• Anything you're unhappy with in the rough mix
• Any creative effects you definitely want kept
• Your reference tracks — two or three songs that represent the sonic target
• The BPM and key if it's not embedded in the file metadata

Common Stem Prep Mistakes

After mixing records for Virgin, Universal, Warner, and 300 Entertainment — plus hundreds of independent releases — I've seen every mistake in the book. Here are the ones that come up most often:

Leaving the limiter on the master bus. Your stems are now all limited and I can't undo it. This is the number one mistake and it compromises every mix.

Not consolidating from bar 1. I get stems that start at random points and nothing lines up. The entire first hour of the mix session becomes an alignment puzzle.

Exporting at the wrong sample rate. If your session is at 48kHz and you export at 44.1kHz, you've introduced sample rate conversion artifacts before I've even started. Match your export to your session.

Sending MP3 stems. MP3 is a lossy format. You've thrown away audio data that I can never get back. Always WAV.

Forgetting the vocal tuning. If you tuned your vocals with Melodyne or Auto-Tune, make sure the tuning is committed/printed to the audio before export. Don't send me raw vocals and assume I'll tune them unless we've specifically agreed to that.

Including muted or unused tracks. If a track is muted in your session, don't export it. I don't need 15 seconds of an idea you abandoned. It just clutters the session.

Quick DAW Export Guides

Logic Pro: File > Export > All Tracks as Audio Files. Check "Include Audio Tail." Set format to WAV, 24-bit. Make sure "Bypass Effect Plug-ins" is unchecked (you want the creative effects, just not the master bus — bypass that separately).

Ableton Live: Select all clips on each track, Consolidate (Cmd+J). Then File > Export Audio/Video. Export each track individually or use "All Individual Tracks." WAV, 24-bit.

Pro Tools: Select all regions, Edit > Consolidate Clip. Then solo each track and bounce, or use "Export Clips as Files" from the Clip menu. WAV, 24-bit.

FL Studio: File > Export > WAV. Check "Split mixer tracks." This creates one WAV per mixer channel. Make sure your routing is clean — one instrument per mixer channel.

How to Send Your Files

Organize everything in a single folder named with the song title and your artist name — something like "ArtistName_SongTitle_Stems." Include your rough mix and notes file in the same folder. Zip it and upload.

At Freshly Baked Studios, we have a Dropbox upload link specifically for stem delivery. You can also use WeTransfer, Google Drive, or any cloud service — just make sure the links don't expire before I've downloaded them.

Good Stems Lead to Great Mixes

I can't overstate this: the quality of your stem prep directly impacts the quality of your mix. When stems arrive clean, organized, and properly formatted, I spend 100% of my time making creative decisions that elevate your music. When they arrive messy, I spend the first chunk of every session just getting organized.

Follow this checklist and you'll get a better mix from any engineer, faster turnaround, and fewer revision rounds. That saves you time and money.
