The Success Rate Metric

Beyond the five core vocal metrics and overall score, there's one more important number: success rate.

What it measures:

Success rate is the percentage of recordings where Q-Orb was able to successfully extract and analyze the vocal data. Not every recording produces usable data — sometimes background noise, technical issues, or incomplete attempts mean the analysis can't run properly.

Success rate = (Valid analyses / Total attempts) × 100

Why it matters:

For teachers: - A consistently low success rate might indicate recording environment issues (too much background noise) - It can reveal technical problems (microphone quality, internet connection) - Very low success rates might mean the exercise is too hard and the student is barely singing

For students: - A high success rate shows they're recording properly and getting good feedback - It's a motivator: "I'm getting better at using the tool itself"

How to interpret it:

• Above 80% is excellent — most recordings are producing good analysis data
• 60-80% is acceptable — some attempts aren't working but most are
• Below 60% suggests troubleshooting is needed — check recording setup, exercise difficulty, or whether the student is completing full attempts

Teaching with this metric: If you notice a student with a low success rate: 1. Check if they're in a noisy environment 2. Ask about their microphone/device quality 3. Ensure they're singing through complete exercises (not stopping mid-phrase) 4. Verify the exercises aren't too difficult (causing them to drop out)

A high success rate means the data you're seeing is reliable — you can trust the other metrics because they're based on solid recordings.
