How to compare two vocal spectrum captures
The capture feature is most useful when the comparison is fair. Fair comparison means same note, same vowel, same microphone setup, and one intentional change.
Choose A and B
Capture the first attempt as A. Change only one variable, such as vowel shape or onset. Capture the second attempt as B.
Look at pitch first
If pitch changed, many other parts of the graph will change too. Try to keep the pitch similar before comparing tone.
Then harmonics
Check whether H3 and H5 became clearer, weaker, or more stable. Avoid deciding based on loudness alone.
Then formants
Look for F1/F2 movement when the vowel changed. This is especially helpful for high-note practice and passaggio work.
How to check this in the analyzer
Choose one note, one vowel, and one microphone distance. Capture the graph before and after one small change. Start by comparing pitch stability, then H1/H3/H5, then F1/F2/F3 candidates.
This is practice feedback, not medical diagnosis or a final technique label. The best result is a sound that is comfortable, repeatable, and useful for the music.
