The number of samples between consecutive analysis frames in windowed-overlap-add processing such as the short-time Fourier transform. It determines the overlap ratio between successive windows and controls the trade-off between time resolution and spectral smearing. Key parameters: sample rate, frame size, and resulting overlap percentage. Persistence mechanism: defined as a standard parameter in signal processing theory, implemented in audio libraries (librosa, MATLAB, scipy), and used in speech recognition and audio analysis pipelines.

Definition
Why it is in scope
The step size in samples between consecutive analysis frames in a short-time Fourier transform or any windowed-overlap-add processing. A human-defined parameter that controls the trade-off between time resolution and computational cost in time-frequency representations. Built to persist as a standard parameter in audio and signal processing.

Hop-size is the step size between consecutive analysis frames in windowed-overlap-add processing. It is only meaningful within a framed/windowed structure: remove frames and hop-size ceases to have any operation or meaning. DEPENDS_ON direction correct — hop-size operates by specifying spacing between frames.
- cmsps9i0v06eejlssqrjcqyviDERIVED_FROM →
Hop-size as a signal processing parameter (interval between successive analysis windows) emerged from the practice of signal processing. Signal processing existed first and fed into the development of hop-size as a concept.

Hop-size is defined as the number of samples between consecutive frames in a short-time analysis. Remove STFT's frame-based windowing and the concept of hop-size vanishes — it has no operation or meaning outside the short-time transform framework.
