Capture workflow
Start the microphone, sing one target sound, freeze or capture the graph, then repeat. Compare two captures from the same note and vowel.
vocal practice tool
A vocal practice tool for comparing your own takes
The best use of the analyzer is not one dramatic graph. It is a small practice log that shows how your sound changes under repeatable conditions.
What to write down
Write the note, vowel, volume, and how the sound felt. The graph becomes more useful when paired with a simple practice note.
A/B comparison
Use capture comparison to see whether pitch, harmonics, or formant candidates changed after an adjustment.
Local-first practice
The workflow is designed around local browser processing. You can learn without creating an account or uploading raw audio.
Frequently asked questions
How often should I capture?
Capture only useful attempts. Too many random captures make patterns harder to see.
Can I use it with a teacher?
Yes. A teacher can use the graph as a shared reference while still listening to the actual sound first.
Should I compare different songs?
Not at the beginning. Compare the same sound first, then use the lesson in real song phrases.
