SoundScope Analyzer

Real-time audio quality analyzer for music streaming

v0.4.2 — Bug fix • Fixes a bug where the spectrum analyzer didn't display on the first capture after opening the popup on a new tab. The audio analysis now starts instantly without needing to stop and restart it manually. v0.4.1 — Major update • Free is now permanent (no more 5-min timer) but limited to 8 core metrics: spectrum, verdict, quality score, cutoff, track ID, DR, LUFS, clips. • Pro Lifetime ($14.99 one-time) unlocks the other 25 metrics including True Peak, K-14, goniometer, spectrogram, EQ curve, MQA detection, A/B comparison, full history, and PNG export. Replaces the previous Pro/Studio subscriptions. • Beta note: feature gating was inactive during beta — all metrics were temporarily unlocked. With v0.4.1, gating is enforced. • New license activation in the popup; locked features now visible (blurred) with upgrade prompts. • Migrated to Polar.sh as Merchant of Record. Performance & stability improvements. _____________________________________ SoundScope — Audio Quality Analyzer Is your streaming service really delivering lossless?
