Main Check: The Plain-English Mix Assistant

[Rene Sens]

If you look at the master bus of a professional mix engineer, you will see a mess of scientific tools: phase correlation meters, fast-fourier transform graphs, and lissajous figures. They are incredibly powerful, but they require you to translate complex visual squiggles into actionable mixing decisions.

Main Check is different. Instead of showing you the math, Main Check listens to the math and tells you exactly what is wrong with your mix in plain English. Acting as an intelligent safety net on your Master track, it analyzes your audio across four critical domains.

Features:

• Stereo & Phase: Context-aware width detection that warns you about phase cancellation, weak centers, and muddy bass.

• Tonal Balance: Compares your frequency distribution against predefined genre profiles.

• Custom "Learn" Mode: Feed the device your favorite reference track, and it will memorize its frequency footprint so you can match it perfectly.

• Dynamics: True Stereo RMS calculation that spots dangerously high transients or heavily over-compressed "sausage" waveforms.

• Technical Health: Surgical brickwall filters catch invisible sub-rumble, DC Offset, and Hidden Clipping (Intersample Peaks) before you export.
