partial frequency trajectory

Partial frequency trajectory refers to the variation in the frequency of a specific partial or harmonic component of a sound signal over time. This can be analyzed using techniques such as Fourier analysis, which decomposes a complex sound signal into its constituent frequencies or partials. By tracking the changes in the frequency of a specific partial over time, it is possible to gain insights into the temporal characteristics of a sound, such as its pitch, timbre, and rhythmic structure. Partial frequency trajectories are commonly used in music analysis and synthesis, as well as in speech and language processing applications.
