A sample-rate-converter is a device or algorithm that changes the sampling frequency of a digital audio signal by resampling, preserving pitch and duration through interpolation and filtering. It persists as firmware in audio interfaces or as software libraries, with parameters: input rate, output rate, filter type, latency.

A sample-rate-converter operates on sampled audio; without sampling there is no signal to convert. Remove sampling and the converter has nothing to process.

A sample-rate converter is a specific kind of signal processing operation that changes sampling frequency via resampling. Specific→general per Law 9, nearest kind signal-processing.
- cmrwfbeuw000csoacnscd6pfoDEPENDS_ON →
Sample-rate conversion requires interpolation to estimate signal values at new sample positions that fall between original samples. Remove interpolation and the converter cannot reconstruct the resampled waveform. The removal test passes: interpolation is the mathematical mechanism that enables resampling.
