1. Click on "Start" to reset all values on default.
2. Upload one or multiple mp3 or wav audio file(s) of your choice.
3. optional: Set the maximum length of the silence here, if there are longer gaps between the sound patterns in a file.
Gap size: 2000 ms
4. optional: If you have uploaded multiple audio files to analyze them in a batch:
Additionally, export a table for each file containing all individual values over time as a .zip file
5. Click on "Analyse" to start the analyzing process.
6. optional: View the formants and their bandwidth in the plot (single file only)
7. Click on "Show JS Arrays" or "Export CSV", to show the recorded data as JavaScript arrays or to export them as a CSV/Excel file.

Bedeutung
Formants (F1-F3)
50 - 4000 Hz
Die zentralen Resonanzfrequenzen (F1, F2, F3) des Vokaltrakts (Mund- und Rachenraum). Sie bestimmen maßgeblich die Klangfarbe.
Formants Energy
0 - 10000
Die energetische Stärke (Intensität) des jeweiligen Formanten.
Formants Bandwidth
0 - 4000 Hz
Die Frequenzbreite des Resonanzgipfels. Gering = scharf/klar, Groß = dumpf/gedämpft.

Meaning
Formants (F1-F3)
50 - 4000 Hz
The central resonance frequencies (F1, F2, F3) of the vocal tract. Key role in determining timbre.
Formants Energy
0 - 10000
The strength (intensity) of the respective formant.
Formants Bandwidth
0 - 4000 Hz
The frequency bandwidth of the resonance peak. Narrow = sharp/clear, Wide = muffled.
