FINDUSTAR / VST3 / AU Free
Focus your low end. Shape the space above it. Free low-frequency mono control with independent high-band stereo width.
Version 1.0.0

Insert Mono Maker on a stereo track, bus or master. Start at 120 Hz with a 24 dB/Oct slope, Mono Amount at 100% and High Width at 100%. Then listen, adjust and level-match.
Removed audition isolates the low-frequency Side signal taken away by Mono Amount. Use it to make deliberate choices instead of narrowing the whole mix.
High Width above 100% increases Side energy and may reduce mono compatibility. Use Mono Check and the correlation meters, then compare at matched loudness.
