Sample Rate Conversion (SRC)

Sample Rate Conversion (SRC) is the process of changing the number of audio samples per second to match different playback or recording standards. For example, converting audio from 48,000 Hz to 44,100 Hz ensures the sound plays correctly on different devices or formats. This involves either adding samples (upsampling) or removing samples (downsampling) while preserving the sound quality. SRC uses digital algorithms to interpolate or decimate data smoothly, preventing distortion or artifacts. Essentially, it ensures audio remains clear and accurate regardless of the sample rate differences between systems.
