Before you start
No registration is required to read this guide.
Steps
- Free includes Detect/Live at 15/30 seconds, transpose, speed up to 2× and the A–B loop, chords and charts on 3 songs a month, side panel, dark mode, piano, tap tempo, metronome and tuner. File analysis is once every 7 days and history shows 5 results.
- The 7-day Pro trial unlocks Pro without a card or automatic charge. ExtensionPay records the trial start; it cannot be extended by reinstalling.
- Pro is monthly, yearly or a one-time lifetime payment; the plans and prices shown come live from ExtensionPay. A subscription can be managed or cancelled from Manage subscription. Use Restore Pro with your existing account when needed.
- Audio is processed locally. Detect captures tab audio; the tuner asks for microphone access only when started. Stop it to release the microphone.
- ExtensionPay receives your email for trial/license management. Anonymous aggregate usage telemetry can be disabled in Settings. It excludes audio, song URLs/titles, email and musical results.
Expected result
You can distinguish local music data, license information and optional usage telemetry.
If it does not work
If restoration fails, check your connection and existing ExtensionPay account. Offline trials still expire at the original date. No purchase or trial was performed during this guide’s checks.
