SoundScope Analyzer

v0.4.7 - Bug fix A/B comparison now measures 30- or 60-second excerpts after 20 seconds of preparation, with independent measurements and improved recording reliability. v0.4.6 - Bug fix Fixed stale cutoff and bitrate readings, including PNG exports. Analysis now resets when a new track is identified, including local files. Clearer results distinguish "No clear cutoff" from "Insufficient signal". _____________________________________ SoundScope — Audio Quality Analyzer Is your streaming service really delivering lossless?
