Frame
A finite block of adjacent samples extracted from a longer signal for localized processing such as spectral analysis or speech feature computation.
Signal Processing Context
A frame is a finite block of adjacent samples processed as a local analysis unit. Speech and audio pipelines convert durations into sample counts using the sample rate and often process overlapping frames at a fixed hop size.
Measurement Boundary
Frame length and hop size describe different quantities: frame length controls the observation window, while hop size controls the distance between consecutive frame starts. Changing either affects temporal resolution, computational load, and boundary behavior.
