Memory limit
Pauses before starting more file work when the selected memory budget is exceeded.
Free configures resources automatically. Pro lets you adjust CPU and memory limits.
Foundations
Documented foundation
The report engine follows recognized loudness standards. Detector findings use a separate, versioned validation methodology designed to remain conservative when the evidence is ambiguous.
Standards behind every report
Programme loudness, True Peak, EBU Mode metering, and Loudness Range are implemented against the following primary specifications.
Evidence behind the Detector
The Detector evaluates spectral cutoffs, retained high-frequency energy, temporal persistence, sample-rate consistency, and contradictory evidence. Its thresholds and safeguards are versioned and tested before release.

These are transparent engineering claims, not third-party certifications. Detector is a forensic screening aid, not proof of a file's provenance.
Options
Free vs Pro
Free includes complete individual-file analysis. Pro removes limits and unlocks grouped, visual, export, and automation workflows.
