Sampling Rate Conversion

Sampling rate conversion is the process of changing the number of audio samples per second in a digital audio file. When converting from a higher to a lower rate, extra samples are removed; from lower to higher, additional samples are created through interpolation. This ensures the audio maintains its quality and plays correctly on different devices or formats that require specific sampling rates. Essentially, it's like adjusting the frame rate of a video so it plays smoothly on various screens without distortion or loss of sound fidelity.
