Focused tools, one at a time.
Phasefold is the first Shadowphase product. The catalog grows one focused tool at a time — never a bundled suite.

Phasefold Client
For clients and collaborators. It opens review sessions exported from Studio; it does not load your own audio files.

// why shadowphase
Focused, by design.
Shadowphase makes one kind of software: focused tools for people who make real listening decisions. Each product does one job, documents what it does, and stays out of the way of the work.
01
Focused tools, not suites
Every Shadowphase product does one job well. No bundled bloat, no menu of features you will never open.
02
Built for critical listening
The tools are made for the moment the decision gets made — careful listening, on the monitors you trust.
03
A quiet, efficient workflow
Software should be quick to reach for and quick to leave. Shadowphase tools add a step to the work, never friction.
04
Technical trust
What a tool measures — and what it does not — is stated plainly. No inflated claims, no hidden behaviour.
Phasefold · Shipping now
Compare mixes without bias.
Phasefold is a standalone decision workflow for mix, mastering, and review. Load versions, match levels, run blind preference tests, and send controlled review sessions to clients.
Aligned
Sources matched in time, sample-accurately. Timing never sways the decision.
Gain-matched
Levels matched before you listen, so the loudest version cannot win by default.
Blind
Switch blind when expectation gets in the way. Labels, metrics, and analyzer data stay hidden during a trial.
