TMM University - Learn The Mix Medic

The App

A quick tour of what you are looking at. Everything lives on one screen.

Think of The Mix Medic like a photo filter app, but for music. You drop in a song, the app analyzes it, you make small adjustments until it sounds the way you want, then you export a polished professional-sounding file.

The whole app lives on one screen. No menus to dig through, no confusing panels. Top to bottom: the visual display, the loudness meter, the sound controls, and the export button.

1
Waveform Display: A picture of your song. The bumps show where the loud parts are. Press play and it turns into a live equalizer.
2
Loudness Meter: Numbers that tell you how loud your master is. You want around -14 to -16 LUFS (the Levels section explains this).
3
Sound Controls: Four sliders (Bass, Mid, High, Warm) that shape the tone. Simple but powerful.
4
Transport Bar: Play, stop, compare Original vs Mastered, and export. Your home base.
5
Export Button: When you are happy with the sound, click this to download your finished master as a high-quality file.

Get Started

How to load your song. It takes less than 10 seconds.

Two ways to load a song: drag it straight onto the page, or click the upload area and pick a file. Works with MP3, WAV, AIFF, and FLAC. The bigger the file (like a WAV), the better the master.

The app scans the song and sets everything up automatically. The waveform appears and the meters start reading. Then you are ready to go.

1
Drop Zone: Drag your audio file anywhere onto the page and let go. The app picks it up and loads it right away.
2
Click to Browse: Prefer a file picker? Click here to browse your folders and select your track. Same result either way.

Use a WAV or AIFF file if you have one. WAV has more detail than MP3, so the mastering engine has more to work with. If you only have an MP3, that works fine too.

Compare: Original vs Mastered

The most important habit. Always compare before you export.

The app keeps your original untouched. At any point you can flip between the original version and the mastered version with a single click. This is called A/B comparing.

This is how the pros work. You switch back and forth quickly while the music plays to hear exactly what changed. If the mastered version sounds better, great. If it sounds worse, pull back your settings. Your ears are the judge.

Transport bar with Original and Mastered buttons

1
Original button: Hear your song exactly as you uploaded it. No changes applied.
2
Mastered button: Hear your song with all your settings applied. This is what will export.
3
Playback position: Shows where you are in the song. Click or drag on the waveform scrubber to jump to any point.
4
Smart Master button: The app analyzes your track and sets the best settings automatically. Great starting point before you tweak anything.

Pro tip: Switch between Original and Mastered while the song is playing, not paused. Your brain catches the difference much faster that way.

Loudness and Levels

The numbers that tell you if your master is at the right volume for streaming.

Streaming services like Spotify and Apple Music turn down songs that are too loud. They target around -14 LUFS. If you master louder than that, they lower your track and you lose the punch. If you master too quiet, your song sounds weak next to other tracks.

The Mix Medic shows two main numbers: Integrated LUFS (the overall loudness of the full song) and True Peak (the loudest single moment in the file). Hit the sweet spot and your track lands exactly where the platforms want it.

1
Integrated LUFS: The average loudness of your whole song. Target: -14 to -16. Green means good. Red means too loud.
2
Short Term LUFS: The loudness of the last few seconds right now. Useful for checking if the chorus is too loud or the verse too quiet.
3
True Peak: The loudest peak in the whole file. Keep this at -1.0 dBTP or lower. Going above 0 causes distortion called clipping.

Simple target: Integrated LUFS around -14 to -16. True Peak at -1.0 or lower. The Mix Medic handles the ceiling automatically so clipping is not something you need to worry about.

Sound Controls

Four sliders that shape the tone of your master. Start here before opening Advanced EFX.

These four sliders are your main tone controls. You do not need to know audio engineering to use them. Think of them like the tone knobs on a guitar amp or the EQ on your phone music app.

Each slider boosts or cuts a range of frequencies. Drag right to add more, drag left to reduce. The waveform display reacts in real time so you can see the change as you hear it.

1
Bass: Controls the low end: kick drum, bass guitar, sub frequencies. Too much and it gets muddy. Too little and the song sounds thin.
2
Mid: Controls the middle frequencies: vocals, guitars, snare. The body of your song lives here. Cut a little if it sounds boxy or nasal.
3
High: Controls the top end: hi-hats, presence, air. Boost for more sparkle and clarity. Cut if it sounds harsh or too bright.
4
Warm: Adds a smooth analog-style warmth. Think vinyl records or tape. A little goes a long way. Pull back if it starts sounding muddy.
5
Presets: Pre-built tone combinations for common styles like Hip Hop, Pop, and Rock. Great starting point. You can tweak after applying one.

Advanced EFX

The plugin rack. Four pro tools behind one button. Optional but powerful.

Click "Advanced" to open the plugin rack. Four tabs appear: Para EQ, Multiband, Exciter, and Imager. These give you deeper control than the basic sliders. You do not need to use them on every song. Try them when you want to fix something specific or push the sound further.

Each plugin has a bypass button so you can flip it on and off while the song plays. Use this to check if it is actually helping before you commit to it.

Para EQ

A surgical equalizer. Find problem frequencies and fix them precisely.

1
Frequency nodes: Each numbered dot on the EQ curve is a control point. Drag up to boost that frequency, drag down to cut. Right-click for shape options (shelf, peak, notch).
2
Live FFT spectrum: The colored background shows the actual frequency content of your song in real time. Bright areas are where the energy is. Use this to spot problem spots.
3
Node detail: Hover or click any node to see its exact frequency, gain amount, and Q value (how wide or narrow the cut or boost is).
4
Bypass toggle: Turn the whole EQ on or off to compare with and without. Click it while the song plays to hear the difference instantly.

Multiband

A compressor that works on each frequency range separately. Great for controlling a boomy bass without touching the highs.

1
Crossover lines: The vertical lines divide the sound into bands. Drag them left or right to change where each band starts and ends.
2
Band controls: Each band has its own Threshold (how loud before it compresses) and Ratio (how much it compresses). The GR meter shows live compression activity.
3
Gain reduction meters: Bars showing how hard each band is being compressed right now. Green is gentle, more color means it is working harder.
4
Amount knob: Master control for the whole multiband. Turn it up to compress more, down to compress less. Start low and increase until it sounds tight and glued together.

Exciter

Adds harmonic sparkle and presence. Makes things pop without just making them louder.

1
Amount: How much exciter effect to add. A little is usually all you need. Too much makes things sound harsh or fizzy.
2
Band controls: Choose which frequency ranges get the excitement. Boosting the high bands adds air and shimmer. Mid bands add presence to vocals and guitars.

Imager

Makes your song sound wider. Like the sound is coming from farther apart on each side. Think of opening a window in a small room.

1
Width slider: Drag right to widen the stereo image. The lows stay centered and mono-safe automatically. Great for making a mix feel more open and spacious.
2
Goniometer: The visual display shows the stereo field. A narrow vertical line means the sound is mostly mono. A wide fan shape means it is spread out in stereo.
3
Stereo field status: Shows MONO SAFE, WIDE, VERY WIDE, or WATCH PHASE. If it says WATCH PHASE, pull the width back a little to avoid phase problems on mono speakers.

Playlist

Master a full EP or album. All your tracks in one session.

The playlist lets you load multiple songs at once. This is useful for EPs, albums, or any time you want to master a set of tracks with consistent settings. Load them all, master them one by one, and export each when it is ready.

Each track remembers its own settings. Switching tracks in the playlist swaps in that track's settings automatically.

1
Track list: All your loaded songs appear here. The currently playing track is highlighted. Click any track to switch to it.
2
Track title: Double-click a track name to rename it. The name you type shows up on the exported file.
3
Tame button: One click finds and reduces the harshest frequency in that track automatically. Good for quickly taming a bright or harsh mix.
4
Add more tracks: Click the plus button to add more songs to the playlist without losing your current work.

Quick Start Guide

Six steps from a raw mix to a finished master. Start here when you are ready to go.

Drop your song on the page

Drag a WAV, AIFF, MP3, or FLAC file onto the app. The waveform loads in a few seconds. The app starts analyzing your track right away.

Hit Smart Master first

Click the Smart Master button. This sets a solid starting point automatically. Press play and listen to the whole song once before touching anything else.

A/B compare Original vs Mastered

While the song plays, click Original and Mastered back and forth. Ask yourself: does the master sound better? Louder? Cleaner? If yes, keep going. If not, try a different preset.

Adjust the tone sliders if needed

Use Bass, Mid, High, and Warm to dial in the sound. Move one slider at a time. A/B after each change. Small moves, not big ones. You are polishing, not rebuilding.

Open Advanced EFX if you want to go deeper

Click Advanced and try the Imager. Drag the Width slider to around 30 to 50 percent. The song should open up and feel wider. Use Para EQ for fixing specific problem spots in the sound.

Check your levels and export

Play the full song and watch the Integrated LUFS number settle. Aim for -14 to -16. True Peak should be -1.0 or lower. Happy with how it sounds? Click Export and save your finished master.

One rule to remember: Trust your ears over the numbers. The numbers tell you if your master works on streaming platforms. Your ears tell you if it sounds good. Both matter, but if you have to pick one, go with what sounds right.

Best practice: Use a song you already know really well for your first test. A track you have heard a hundred times. You will hear every change more clearly on familiar music than on something new.

Every time you change a setting, A/B against Original. This is the single most important habit in mastering. It keeps your ears honest.
