Definition. Defined in technical language, spectral music is an acoustic musical practice where compositional decisions are often informed by sonographic representations and mathematical analysis of sound spectra, or by mathematically generated spectra. The spectral approach focuses on manipulating the spectral features, interconnecting them ...
Mel-frequency cepstrum. In sound processing, the mel-frequency cepstrum ( MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients ( MFCCs) are coefficients that collectively make up an MFC. [ 1]
In speech science and phonetics, a formant is the broad spectral maximum that results from an acoustic resonance of the human vocal tract. [ 1][ 2] In acoustics, a formant is usually defined as a broad peak, or local maximum, in the spectrum. [ 3][ 4] For harmonic sounds, with this definition, the formant frequency is sometimes taken as that of ...
A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called waterfall displays .
In modern academia, music theory is a subfield of musicology, the wider study of musical cultures and history. Music theory is often concerned with abstract musical aspects such as tuning and tonal systems, scales, consonance and dissonance, and rhythmic relationships. In addition, there is also a body of theory concerning practical aspects ...
Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [ 1 ][ 2 ][ 3 ] psychophysics, [ 4 ] organology [ 5 ] (classification of the instruments), physiology, [ 6 ] music theory, [ 7 ] ethnomusicology, [ 8 ] signal processing and instrument building, [ 9 ] among other disciplines.
The method of reassignment is a technique for sharpening a time-frequency representation (e.g. spectrogram or the short-time Fourier transform) by mapping the data to time-frequency coordinates that are nearer to the true region of support of the analyzed signal. The method has been independently introduced by several parties under various ...
Sensations of Tone. Helmholtz resonator, p. 121, fig. 32. On the Sensations of Tone as a Physiological Basis for the Theory of Music (German Die Lehre von den Tonempfindungen als physiologische Grundlage für die Theorie der Musik ), commonly referred to as Sensations of Tone, is a foundational work on music acoustics and the perception of ...
