Can you hear the difference between a good mix and a broken one?
Fix The Mix is an ear training lab for producers and sound engineers. In 60-second sessions, you train the ear you need for mixing: frequencies, dynamics, stereo field, rhythm, and sonic character.
No endless theory. You listen, you decide, and we explain why.
—WHAT YOU'LL TRAIN—
• EQ Surgeon—Match the target EQ curve. Learn to hear which frequencies changed and by how much.
• Stereo Space—Place each instrument in the stereo field. Train imaging and depth.
• Frequency Drop—Drag each instrument into its area of the spectrum. Build your frequency map.
• Gain Rider—Tame 20 dB of dynamics while keeping the fader in the green zone.
• Beat Drop—Hold the groove against the metronome. Rhythmic precision. • Mix & Match — Recognize genres, synths, and drum machines by their sonic character. Can you distinguish a TR-808 just by its kick drum?
• Stem Stacker — Destroy blocks and restore the stems in the mix.
• Chord Cosmos — Build progressions in the Circle of Fifths.
• Mix Space — Your first space mix: move spheres and hear how everything changes.
