We measured everything. Twice.

Sphinx 101 ships with the same test results we run on every build. Thirteen independent suites. 2,000+ automated measurements. The raw data is yours to inspect - we are improving everything continuously, and Sphinx 101 is work in progress with the community.

Sphinx Channel ships with the same test results we run on every build: full signal chain integrity, component-model verification, alias regression, and per-instance variation - measured on every release, with the exact per-suite counts listed in the shipped reports.

Read more about our currently simulated analog circuit physics here.

Every suite is also validated with real music material alongside the synthetic test signals. A calibrated commercial master is pushed through the actual welcome preset and metered the way a DAW meter does - because mono and synthetic tones can mislead on level. It is the authoritative check that the chain stays loudness-transparent on real, bass-heavy, stereo program material.

Check them yourself. Compare against your own hardware if you have it. Give the reports to your AI of choice to explain. We publish what we measure because we expect you to verify - most analog-simulating audio plugins ship just a promising press release; we ship the raw and verified test results. Sphinx 101 is work in progress, and gets better with every update. Download the free demo.

Check them yourself. Compare against your own hardware if you have it. Give the reports to your AI of choice to explain. The same reports ship inside every Sphinx Channel installer, next to the manual. Beyond the synthetic signals, the battery runs a real-music level section: a calibrated commercial master through the actual welcome preset, metered the way a DAW meter does - the authoritative check that the chain stays loudness-transparent on real, bass-heavy, stereo program material.
