Understanding Samples per Second: What 128 kHz Means for Audio Quality and Performance When diving into digital audio, one of the key technical specifications you’ll encounter is samples per second, commonly expressed in kilohertz (kHz). Among the most relevant values today, 128 kHz stands out for its impact on sound fidelity and professional applications. Whether you're a musician, producer, or audio enthusiast, understanding what 128 samples per second represents helps you make informed decisions about equipment and audio quality. ### What Are Samples per Second? In digital audio, audio signals are captured as discrete data points at regular intervals—each timestamped sample. The rate at which these samples are recorded is measured in samples per second (pps) or samples per second (S/s), equivalent to Hertz (Hz). For example, 44.1 kHz means 44,100 samples per second. This frequency determines how accurately the analog sound wave is reconstructed in digital form.
