• Added guided acoustic test flows and test history for reference tone, sweep, noise, channel, and low-frequency checks. • Sweep playback now supports single, fixed-count, and continuous loops with direction and interval controls. • Share bilingual test result cards, and import or export custom presets. • Share calibration reports as PDF, CSV, or response-curve PNG files.

Improved test presets, calibration report export, real-time spectrum analysis, and Settings organization.

Added a one-click test preset pack with built-in acoustic check scenarios, including 1 kHz reference tone, full-range sweep, pink noise, white noise, left/right channel checks, and low-frequency response check. Added calibration report export, allowing the active calibration profile’s test points, correction values, route details, and summary to be exported as a local text report for records or support handoff. Improved the preset workflow so common tests can be loaded instantly while keeping user-created presets separate and fully manageable.
