How to use a vocal spectrum analyzer for singing

A vocal spectrum analyzer is most useful when you compare the same note under the same conditions.

Start with one stable note

Use a comfortable vowel and hold it for about three seconds. Watch whether the pitch stays steady before interpreting harmonics or formants.

Read pitch, then harmonics, then formants

Pitch tells you the note. H1, H3, and H5 show harmonic energy. F1, F2, and F3 are resonance candidates shaped by your vowel and vocal tract.

Capture useful graph moments

Freeze or capture the graph when the sound feels useful. Compare it with a synthetic reference example or a second attempt instead of trusting memory alone.

Try it in the analyzer. Capture the graph, then compare it with a reference example or your next attempt.
