Sampling Rate
The number of samples used per second to represent a signal.
Technical Context
The number of samples used per second to represent a signal.
Sampling rate is not a quality metric by itself; analogue bandwidth, bit depth, and resampling-filter behaviour must be considered with it.

Same Quantity as Sample Rate
Sampling rate and Sample Rate are two common English names for the same physical quantity: the number of samples per second, usually written as f_s. Signal-processing literature often uses the term "sampling frequency," while audio and ASR configurations commonly use "sample rate."
Selecting f_s is not only a Nyquist calculation. The analogue anti-alias filter transition band, sensor or codec bandwidth, resampling chain, and the sample rate used to train a downstream model can all constrain the engineering choice.
