  SoundScope — Audio Quality Analyzer
  
  Is your streaming service really delivering lossless?
  
  SoundScope captures the audio playing in your browser tab and analyzes it in real time. You see the frequency spectrum, a quality verdict, and a score from 0 to 100 — no guesswork, no golden ears required, just data.
  
  One click. The truth, instantly.
  
  WORKS WITH YOUR STREAMING SERVICE
  
  Track detection works automatically across the major music streaming platforms, whether you use a mainstream service or a lossless-focused one.
  
  WHAT YOU SEE
  
  • Real-time frequency spectrum with instant verdict: Lossy / Lossless / Hi-Res
  • Audio Quality Score (0–100) — one number that tells the whole story
  • Codec detection with estimated bitrate and cutoff frequency
  • Track title, artist, and platform identified automatically
  
  STUDIO-GRADE METRICS
  
  • Dynamic Range (DR), LUFS, True Peak (dBTP), Bit Depth
  • Crest Factor, PLR, Spectral Centroid, LRA, Noise Floor
  • K-14 metering, M/S balance, stereo width, phase correlation
  • Tonal balance curve, waveform, goniometer, spectrogram
  • Listening Fatigue indicator, source type detection
  
  COMPARE AND TRACK
  
  • A/B comparison — record two sources, see every metric side by side
  • Listening history — a log of every track with its quality verdict
  • Export analysis as PNG
  
  100% LOCAL, 100% PRIVATE
  
  • All analysis runs inside your browser. No audio is recorded, stored, 
    or transmitted.
  • No account required.
  • No tracking, no telemetry, no cloud sync.
  
  PRICING
  
  Free during launch — every feature unlocked, 5-minute sessions.
  A Pro plan with unlimited session length will be offered later as a 
  one-time purchase with a lifetime license. No subscription, ever.
  
  HOW IT WORKS
  
  1. Open a supported streaming service and start playing a track.
  2. Click the SoundScope icon in your Chrome toolbar.
  3. Watch the analysis unfold live — spectrum, verdict, metrics, all 
     updated in under 100 milliseconds.
  
  Built for audiophiles, music producers, mastering engineers, and anyone 
  who wants to know what they're actually hearing.

  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.
