48kHz

Also written: 48 kilohertz

48 kilohertz, a standard audio sample rate capturing 48,000 sound samples per second.

In plain terms

48kHz refers to 48,000 samples per second. This is a common rate for digital audio, meaning sound is measured and recorded that many times every second.

Higher sample rates generally capture more detail in the sound. For example, music and professional audio often use 48kHz or even higher rates to ensure high fidelity.

The expert version

48 kilohertz (kHz) is a standard sample rate for digital audio, representing 48,000 discrete measurements of an audio signal taken per second. This rate is widely adopted in professional audio production, digital broadcasting, and video production due to its balance between fidelity and data size.

Compared to lower rates like 44.1kHz (CD quality), 48kHz offers slightly better performance for certain applications, particularly in video synchronization and professional audio workflows. The choice of sample rate impacts the Nyquist frequency, which is half the sample rate, determining the highest frequency that can be accurately represented.

Why it matters now

This term is appearing because AI models are increasingly being used to generate and manipulate audio. Specifically, Google's Lyria 3 Clip model uses 48kHz as a standard sample rate for creating music clips, highlighting the growing intersection of AI and high-fidelity audio production.
