Founders Campaign · Through May 31

Help MIXPrep become the industry standard for pre-mix intelligence.

Five supporter tiers, from $97 Core to $997 Virtual Board. Each tier credits you in the launch story and locks founders pricing forever. After May 31, founder tiers close and Core moves to $199.

Multiple payment options available on each tier below.

The Problem

You got into mixing to mix. Not to rename 120 files.

Every session starts the same way. A Dropbox link. A zip file. A folder full of chaos. And the next 45–90 minutes of your life disappear before you touch a single fader.

01

The Name Game

Audio_Track_14.wav. bounce_v3_FINAL(2).wav. You spend 15 minutes just figuring out what each track is — kick, snare, or somebody's rough vocal comp.

02

The Gain Lottery

Tracks arrive at wildly different levels. That "quiet" guitar clips your mix bus. That "loud" vocal barely registers. You re-gain every. single. track.

03

The Reference Hunt

The artist says "make it sound like The Weeknd." You open Spotify, scroll through 15 tracks, and still aren't sure which one fits this session's vibe.

04

Flying Blind

You start mixing without knowing the key, tempo, phase issues, or sub-bleed. You discover problems 2 hours in. Then you're troubleshooting instead of mixing.

That's not mixing. That's data entry. MIXPrep handles the prep so you can get to the part that actually matters.

Sound familiar? There's a fix, and it's locked at Founder pricing right now.

How It Works

Drop a folder. Get a mix-ready session.

1

Drop a folder or zip onto MIXPrep.

Any folder of audio multitracks or a zip file. WAV, AIFF, FLAC, MP3. Any sample rate, any bit depth.

MIXPrep drop screen — clean landing screen with drag-and-drop zone

Drop a folder and MIXPrep takes it from here.

2

MIXPrep listens to your tracks and categorizes what it can.

Vocals, kick, snare, room mics, pads, and 32 more categories. TrackSense recognizes from the audio itself, not just filenames. Vocals especially well. Anything it can't confidently identify gets flagged so you can preview, label, and move on. Across 100+ tracks in seconds, not minutes.

3

Every track gets gain-staged to the right level for what it is.

Not one flat target for everything. Your kick gets different headroom than your room mic. Your vocal gets different headroom than your bass DI. Category-aware gain staging, calibrated from real sessions.

MIXPrep SMART Gain mode selection — choose between SMART, Peak, and RMS gain staging

Choose your gain mode — SMART, Peak, or RMS — before processing.

4

Clean, readable names where we have them. Honest flags where we don't.

Filenames like "Lead_Vox_v3_FINAL.wav" become "Lead Vox" instantly. Pure placeholders like "Audio_Track_14.wav" stay flagged with a NO NAME badge until you take a 2-second listen and label them. We won't make up a name we don't actually know.

5

You get a full session report — the MIXBrief.

Key, tempo, track count by category, frequency relationships, and an overview of what you're working with. Know the session before you open your DAW.

6

Start at a proven mix balance with MIXPrint.

Load a reference mix you love. MIXPrint captures the per-category balance as a reusable template. Every new session starts at that proven balance — skip the rough mix guesswork entirely.

7

AI-matched reference tracks that fit your session.

MIXRef analyzes the genre and sonic profile of your session, then suggests professional releases that match. Audition them side by side with SonicLens. Verified engineer credits on every recommendation.

Your session goes from a pile of mystery files to an organized, gain-staged, fully analyzed project. In minutes instead of an hour.

That's the workflow. Five tiers to back the work and lock your pricing in for life.

Starting at $97. After May 31, Core moves to $199.

Features

Everything you need. Nothing you don't.

Built by a mix engineer who got tired of prepping sessions the hard way.

TrackSense

37-Category Audio Recognition

TrackSense listens to the audio content, not just the filename. Vocals categorize especially well, along with kick, snare, room mics, and 33 more categories. Tracks we can't confidently identify get flagged with a NO NAME badge so you can preview, name them in one click, and move on. Every correction trains the teachable dictionary, so MIXPrep gets smarter every session.

SMART Gain

Category-Aware Gain Staging

Session-Matched Adaptive Ratio Targeting. Your kick, your vocal, and your room mic each get the right amount of headroom for what they are. Not one flat number for everything. Calibrated from real-world mix sessions.

MIXPrint — New

Scan Your Best Mix Once. Start Every Session at That Balance.

Load a reference mix you love, and MIXPrint captures the per-category balance as a reusable template. Every new session starts at that proven balance — with per-category lock and SMART toggle so you stay in control of every track type. Stop building rough mixes from scratch. Start where your last great mix left off.

Clean Names

Readable Labels From Real Filenames

"Lead_Vox_bounce_v3_FINAL(2).wav" becomes "Lead Vox" instantly. Pure placeholder names like "Audio_Track_14.wav" stay flagged with a NO NAME badge so you can preview the audio and label them in one click. We don't guess what we don't know.

MIXBrief

Your Musical Intelligence Report

Before you open your DAW, MIXBrief gives you the overview: key, tempo, track count by category, kick/bass relationship, and a plain-English summary of what the session looks like. With the AI add-on, get deeper analysis including frequency relationships and mix approach suggestions. Export as PDF for clients.

MIXRef + SonicLens

Reference Tracks That Actually Match Your Session

Stop scrolling Spotify hoping to find the right reference. MIXRef analyzes your session's genre, energy, and sonic profile, then recommends verified professional releases. SonicLens lets you audition references side by side with 30-second previews. Confidence scoring on every pick. Every recommendation comes with verified mixer, producer, and mastering credits — not guesses. Grammy, Dove, BET, and Billboard award badges appear right on the card.

MIXRef reference cards showing Al Green and Earth Wind & Fire matches
MIXRef reference cards showing Aretha Franklin and Boyz II Men matches

AI-matched references with verified engineer credits, award badges, and confidence scores.

PhaseSyncBeta — Coming Soon

Automatic Phase Alignment for Multi-Mic'd Instruments

Drop your drums, guitars, vocals — PhaseSync detects which mics belong together, finds the optimal time alignment, and fixes phase issues in seconds. No manual nudging. No trial-and-error polarity flipping. No $149 plugin required. Currently in beta with launch week buyers getting first access.

Session Intelligence

Key, Tempo, Time Signature — Detected Automatically

MIXPrep auto-detects key, tempo, key changes, and time signature from the audio itself. Know exactly what you're working with before you open your DAW. No metadata guessing, no manual BPM tapping.

MIDI Key Map Export

Auto-Tune and Melodyne Setup in One Click

Export a MIDI key map based on detected key and key changes. Load it directly into Auto-Tune, Melodyne, or any pitch correction tool. Skip the manual scale setup entirely.

Worship Mode (coming summer 2026): preset key-map tuning for the half-step modulations and bridge key changes worship engineers actually hit.

Low-End Diagnostic

See Sub-Rumble Before Your EQ Does.

Sub-frequency analysis flags every track that has unnecessary low-end energy, so you know exactly where to clean up before you even open an EQ plugin.

Track Translator

International Sessions? Handled.

170+ audio terms in 15+ languages. MIXPrep auto-detects international sessions and translates track names so every stem makes sense, no matter where the session originated.

Privacy-First

Your Audio Never Leaves Your Machine (Unless You Say So)

Core processing runs 100% locally on your computer. MIXRef's default reference matching uses metadata and analysis data only, not your audio files. The optional Enhanced Mode (off by default) uploads short audio analysis to Google for deeper matching. For pre-release or major-label sessions under NDA, leave Enhanced Mode off and your audio never leaves your machine.

Everything you just read, locked in at Founder pricing.

Who This Is For

If you open session folders for a living, this is for you.

Mix engineers doing 2+ sessions a week who are tired of burning prep time
Freelance mixers juggling sessions from different artists, producers, and studios — where every folder is a different kind of chaos
Producers who mix their own work and want to start from an organized, gain-staged foundation
Engineers working in any genre — hip-hop, R&B, rock, country, pop, worship, electronic, Latin, metal, jazz. If it comes as a folder of multitracks, MIXPrep handles it.
Anyone who's ever opened a 120-track session folder and felt their stomach drop

This is not genre-specific. This is not DAW-specific. If you receive audio files and need to make sense of them before mixing, MIXPrep saves you time on every single session.

FAQ

Questions? Answers.

Is MIXPrep available for Windows?
macOS Apple Silicon (macOS 15+) is the production build and where I run MIXPrep daily. Windows and Intel Macs are in active beta. v1.4.4 is the latest build with the major Windows-specific fixes (drag-and-drop now copies instead of moving source files, the silent install crash is diagnosed and fixed, the process worker no longer hangs on protected folders). Activation and licensing are solid across all platforms (three-device licensing, magic-link recovery, the works). A few visual polish items on Windows are still on the queue for the next patch. If you buy in today on Windows or Intel Mac, you get the current build (installer, portable, and debug variants for Windows), a direct line to me at david@themixacademy.com, and the 30-day money-back guarantee. No awkward hoops if it isn't working for your setup. You also lock in the $97 launch price for life (it's going to $199 once stable). Target for full Apple Silicon parity on Windows and Intel: a few more weeks. If you'd rather wait until then, email me and I will hold your $97 slot.
What file formats does it support?
WAV, AIFF, FLAC, and MP3. Any sample rate, any bit depth. Drop in a folder OR a .zip file (MIXPrep extracts it for you). Just point it at the multitracks and MIXPrep does the rest.
What genres does it work with?
All of them. TrackSense recognizes 37 categories that span every genre, from hip-hop to country to metal to worship to Latin pop. SMART Gain targets are calibrated from real sessions across multiple genres. And if your session arrives in another language (Spanish, Portuguese, French, more), Track Translator translates the filenames into your native language so you can sort and organize without needing to learn audio terminology in 15 other tongues.
Does my audio get uploaded to the cloud?
Core processing (TrackSense, SMART Gain, MIXPrint, Clean Names, MIXBrief) runs 100% locally on your machine. Your multitracks never leave your hard drive. MIXRef's default mode uses metadata and analysis results only, not your audio files. MIXRef's optional Enhanced Mode (off by default) uploads short audio analysis to Google Gemini for deeper matching. You'll see a clear toggle before it happens, and you can leave it off entirely. For pre-release material or major-label sessions under NDA, stay in default mode and you're fully air-gapped.
How accurate is TrackSense?
On tracks with real filenames or recognizable audio content, engineers report 90%+ accuracy out of the box. Vocals categorize especially well. Tracks with pure placeholder names like "audio_1.wav" stay flagged until you preview and label them. We don't guess what we don't know. Every correction trains the teachable dictionary, and most engineers see 95%+ accuracy on familiar session types after a few rounds.
Does MIXPrep work with VoiceOver, screen readers, or keyboard-only navigation?
We're actively auditing MIXPrep for VoiceOver compatibility, keyboard navigation, color contrast, and high-contrast display. The app isn't fully accessible yet — we'd rather tell you that honestly than pretend otherwise. If you rely on assistive technology, email david@themixacademy.com before purchasing so we can be honest about what works today and what's in progress — and so your feedback can shape what we ship next. Engineers with vision loss make great mixes too, and we want MIXPrep to be a tool you can actually use.
What does the Pro Founder tier ($147) add?
It's the difference between session prep and session intelligence. MIXBrief Pro is the premium HTML Session Intelligence Report you'll actually want to open before mixing: mix approach notes tailored to your session's genre, frequency relationships called out per track, and a checklist that travels with you into the mix. MIXRef + SonicLens take the reference hunt out of your day, surfacing a running list of professional references matched to your session in 30 seconds and letting you A/B them with 30-second previews. PhaseSync beta access gets your kit and re-amps phase-locked automatically the moment it ships in summer 2026. The throughline: you open your DAW already knowing what the mix needs, where to focus, and which moves to start with.
What is MIXPrint?
MIXPrint lets you scan a reference mix you love and capture the per-category balance as a reusable template. Every new session starts at that proven balance. You get per-category lock and SMART toggle so you stay in control. Think of it as starting every mix where your last great mix left off.
What if TrackSense gets a track wrong?
Click the track to preview the audio, then pick the right category from the dropdown. The teachable dictionary remembers your correction and applies it on future sessions. Same workflow for placeholder-named tracks that came through flagged with NO NAME: preview, label, move on. Accuracy improves significantly after a few rounds.
What is PhaseSync?
PhaseSync is our proprietary phase alignment engine, coming summer 2026 (target v1.5). It automatically detects which mics belong together (snare top/bottom, kick in/out, guitar close/room), finds the optimal time alignment, and fixes phase issues with no manual nudging required. Pro Founders and above get beta access the moment it launches.
What's the difference between Core at $97 and the Pro layer at $49/year?
MIXPrep Core at $97 is the full desktop app — TrackSense categorization, SMART Gain, MIXBrief session reports, MIXPrint balance fingerprinting, everything that runs on your machine. One-time payment, permanent access. The Pro layer is an optional add-on at checkout that unlocks MIXRef (AI-matched reference tracks), SonicLens (side-by-side reference audition), MIXBrief AI (deeper analysis and approach suggestions), and PhaseSync beta. It's $49/year, billed annually, cancel anytime. Core features always work without it.
Does MIXPrep modify my original files?
Never. MIXPrep creates organized copies. Your original multitracks are never touched, renamed, or moved.
What DAWs does it work with?
MIXPrep is DAW-agnostic. It processes your files and outputs organized, gain-staged copies you can import into Pro Tools, Logic, Ableton, Studio One, Cubase, Reaper, or any other DAW.
Is there a refund policy?
Yes. 30-day money-back guarantee, no questions asked. If MIXPrep doesn't save you real time on real sessions, email me and you'll get a full refund.
How is this different from just organizing my files manually?
It's the same outcome in a fraction of the time. MIXPrep does in 30 seconds what takes you 30–60 minutes by hand — and it does the gain staging with category-specific intelligence that you'd have to calculate manually for each track type. Plus MIXPrint gives you a starting balance no manual workflow can match.
macOS says it can't verify MIXPrep. Is it safe?
Yes — completely safe. MIXPrep is code-signed and notarized with Apple, so most Macs will open it without any warnings. If you do see a Gatekeeper prompt (rare on older macOS versions), just open Terminal and paste: xattr -cr /Applications/MIXPrep.app — then open normally. One time only.

MIXPrep runs entirely on your machine — your audio files never leave your computer.

The Story Behind MIXPrep

Born out of necessity. Built with obsession.

I'm David Glenn. Mix engineer, founder of The Mix Academy. Over 20 years mixing professionally, teaching engineers the whole way. I stepped away for a season — life, health, all of it. When I came back, able to work again, I hit a snag I didn't expect.

The prep tool I'd used on every session for years wouldn't even open. Just… dead. And it forced a question I couldn't ignore: why am I still spending the first hour of every mix doing work that doesn't require my ears?

Renaming tracks. Sorting multitracks. Fixing gain staging. Trying to make sense of someone else's session. That's not mixing. But it's where all your best energy goes.

So I started building a small utility — just enough to handle gain staging and mono conversion. That was the plan. But then the hyperfocus kicked in. One fix turned into another, and pretty soon it wasn't a tool anymore. It was a system. Every feature built around one idea: the mix starts before you ever touch a fader.

Here's the part that still gets me. My very first course, back in 2011, was called "The Mix Prep Series." Gain staging. Session organization. The fundamentals. Fifteen years later, the thing I was teaching became the thing I'm shipping. Same fundamentals. Different form. Full circle.

I built this because I needed it. I'm sharing it because I think you need it too.

Your next session could take half the prep time.

Drop a folder. Get organized files, category-aware gain staging, and a full session report. Start mixing instead of prepping.
