Voice Analyzer

DEXUS Pawel Krzywdzinski
Voice Analyzer is a real-time spectrum and spectrogram analyzer. It gives you a visual representation of your voice. You can also analyze the sounds of musical instruments, identify spoken words phonetically, or picture the calls of different animals.

With the Voice Analyzer you can check and develop the Singer’s Formant and vibrato, the most important measures for every singer. The Singer’s Formant is a tonal ‘ring’ produced by a singer. It is only visible on the sound spectrum of trained singers (the spectral peaks of harmonics around 2500 to 3500 Hz). This formant is absent in speech or in the spectrum of untrained singers.
