Microphone setup for voice frequency analysis
Before judging your voice, make sure the microphone is not changing the result too much.
Keep distance consistent
Start around 15-25 cm from the microphone. If you move closer, low frequencies can look stronger.
Avoid clipping
If the input clips, harmonics and formants become unreliable. Lower the input level before interpreting the graph.
Use the same setup
Practice comparisons only work when the room, mic angle, and input level stay similar.
Try it in the analyzer. Run the four-second check, then compare it with your next attempt.
How to check this in the analyzer
To apply this article, start with one comfortable note, one vowel, and a fixed microphone distance. A single graph is less useful than repeated captures under the same conditions.
After capturing the graph, compare it with your next attempt. Look for pitch stability, whether H3 and H5 remain visible, and whether F1 or F2 candidates move when the vowel changes. These cues are practice references, not medical or professional diagnosis.
