FFT

FFT (or Fast Fourier Transform) is a tool used to represent graphically the spectral constituents of a sound. The sound is mathematically analysed and is reduced to its various overtone components in their dynamic evolution over time. The graphic representation of an FFT usually plots the amplitudes of the frequency bands over time, offering a highly readable and visual representation of the sound being examined.

FFT

La FFT (ou Transformée de Fourier Rapide) est un outil utilisé pour la représentation graphique des constituants du spectre d'un son. Le son est analysé mathématiquement et réduit sous la forme de données correspondant à l'évolution temporelle de la dynamique de ses partiels. La représentation graphique d'une FFT est généralement constituée de l'évolution de l'amplitude des bandes de fréquences dans le temps, offrant ainsi un graphique facilement utilisable.

FFT

Con FFT (Fast Fourier Transform) si intende uno strumento per l'analisi e la rappresentazione grafica degli elementi costituenti uno spettro sonoro. Il suono viene analizzato matematicamente e ridotto a dati che corrispondono all'evoluzione temporale della dinamica delle parziali. La rappresentazione grafica di una FFT è costituita generalmente dall'evoluzione dell'ampiezza delle bande di frequenza nel dominio del tempo, e offre all'utente una rappresentazione del suono intuitiva e facilmente utilizzabile.

Acronimo di Fast Fourier Transform: trasformata di Fourier. Consiste nella scomposizione di un fenomeno periodico nelle sue componenti sinusoidali armoniche e viene perciò usata per eseguire l'analisi spettrale di un suono. L'analisi viene generalmente rappresentata dal grafico in ampiezza e tempo di tutte le sue componenti frequenziali.

FFT

La FFT (o Transformada Rápida de Fourier) es una herramiento utilizada para representar gráficamente a los componentes del espectro de un sonido. El sonido es analizado matemáticamente y reducido a sus diversos parciales en su evolución dinámica en el tiempo. La representación gráfica de una FFT usualmente traza las amplitudes de las bandas de frecuencia en el tiempo, ofreciendo una representación visual de fácil lectura del sonido que esté siendo examinado.
