4.4. Audition and Gain Guidance

Each analyzed Mix row shows a signed track-gain recommendation. This matches the track to a fixed ECMA-based reference and does not change when other tracks are added or removed. That stability makes it practical to copy the individual values into a DAW.

The Active Mix target sets the desired integrated loudness for the complete Mix. Harmonic DJ calculates one common pre-limiter gain from the gain-adjusted track average. Changing the target or tracklist changes this common value without rewriting the individual track recommendations.

Harmonic DJ applies both values during audition so playback follows the active Mix target. It does not write processed audio, add a limiter, or make transition-treatment decisions for you.

Track gain is post-planning advice. It never changes whether a route or transition is accepted.
