Plug-ins for macOS

Tools that behave like hardware you trust.

Two focused instruments, one interface language. Everything you touch moves, meters and reports the value it is actually applying.

Hear it first

Both plug-ins, dry and processed

Real renders from the plug-ins, switched instantly so the playhead never moves. Both takes in each pair are matched to −12.0 LUFS integrated with peaks at or below −1 dBTP, because at different levels the louder one always wins and the comparison tells you nothing.

Mastering Suite · unmastered vs mastered Real render · matched −12 LUFS
The StudioZIO Mastering Suite window: a signal-path rail across the top running M/S engine, saturation, pink match, glue, maximizer, tone EQ, clipper and limiter, with the Pink Match stage open at 60 per cent against a Hip-Hop target, and a meter column on the right reading -14.3 LUFS integrated against a -14 target, with true-peak bars and stereo correlation.
Output

“Güvercinler”, a StudioZIO production, rendered through Mastering Suite 2.0.0. Judge tone, depth and stability.

Tempo Delay · dry vs delayed Real render · matched −12 LUFS
The StudioZIO Tempo Delay window: a signal-path rail across the top running tempo, left, right, tone, feedback, character, width and mix, with the primary delay engine open at 100 ms on each side, 45 per cent feedback, 100 per cent width and 50 per cent mix, a stereo echo field on the right, and the tone and filters tab showing an 80 Hz high-pass and an 8 kHz low-pass.
Output

Rendered through Tempo Delay 4.0.1 at 44.1 kHz. Judge placement, tail and stereo spread.

The through-line

Measurement is not a separate product

The industry sells you a processor, then sells you a meter to find out what the processor did. StudioZIO puts both on one surface, and makes the honest comparison the default one.

You never have to trust your ears alone

Momentary, short-term and integrated loudness, loudness range, crest factor, sample peak, true peak and stereo correlation update while you work. No second plugin, no bouncing to check.

Louder is not allowed to win

Gain match levels the bypassed and processed paths before you compare, and delta monitoring plays only what the chain added. Both exist because an unmatched A/B always flatters the louder side, whatever it actually did to the sound.

Automation is a first-class surface

Every control is a parameter with a stable identifier, so automation lanes, macro mappings and saved sessions survive updates instead of silently re-binding.

32 automatable parameters

Nothing allocates on the audio thread

Bypass is crossfaded rather than switched, so engaging it produces no transient. Filter cutoffs cannot cross and destabilise the loop. These are the parts nobody demos and everybody notices.
