Real-Time FFT Acoustic Oscilloscope & 16-Band Spectrum for French Horn

Acoustic Anatomy: The French Horn Formant & Timbre Profile

The characteristic velvet warmth of a master hornist arises from dense harmonic energy concentrated in the 650Hz–850Hz formant band, while upper projection and clarity stem from coherent partials extending between 2kHz and 3kHz. Under relaxed resonance, the FFT spectrum displays an evenly tapered harmonic envelope.
