How to read detection results

hzdetect reports the note it hears and the estimated A4 reference. That A4 number is the key.

How to interpret it:

• If the A4 value is near 440, the track is standard tuning
• If it is near 432, the track is tuned lower
• If it matches a Solfeggio target, you will see a matching display name

What to do next:

1. Confirm the reading is stable (quality dot stays green).
2. If the A4 value is not your target, retune your own file.

Do not assume that a label is correct. Detection tells you what is real; retuning gives you control.
