Huge in the studio. Still there on a phone.
Fiix listens, finds where the mix cancels in mono and repairs it in real time. No thresholds, no angles. One button per band.

Go wide without wrecking your mono.
Four bands. Widen, thicken and image each one on its own while the mono sum stays exactly where it was.

True-peak limiting that follows the track.
A release synced to the tempo, a clipper in front for the transients that do not need the limiter, MID and SIDE, and LUFS metering on the output so you ship to the number you meant.

Glue that matches its own level.
A mastering bus compressor with MID and SIDE compression, sidechain EQ, CLIP and COLOUR, and an AUTO GAIN that matches output to input and locks, so you judge the tone and not the volume.

Louder, not broken.
Lifts the quiet detail and adds smooth odd harmonics, so the sound sits louder and further forward while the peaks stay put.

Move anything out of the way.
Carves space for the kick, from a smooth tempo-synced pump to spectral carving that only dips the frequencies where kick and bass collide. Then it lines both up in phase.

Read the whole master at a glance.
Peak, RMS, VU, LUFS and true peak on one zero-latency rail that passes your audio through bit-identical. Beneath it, a spectrum, a loudness history, a goniometer and a BPM counter that reads the music itself.
