Understanding Audio Sample Rates: 44.1kHz vs 48kHz
Sample rate defines how many digital snapshots of sound are recorded each second. Discover why 44.1kHz and 48kHz are the two industry standards.
44.1kHz is the standard for music CDs and music streaming. 48kHz is the standard for video production, TV broadcasting, and cinema audio.

What is Sample Rate?
According to the Nyquist-Shannon sampling theorem, capturing frequencies up to 20kHz (human hearing limit) requires a minimum sample rate of 40kHz.
44.1kHz: Music Standard
Historically chosen for Compact Discs due to compatibility with PAL/NTSC video tape recorders.
48kHz: Video & Cinema Standard
Divides evenly into video frame rates (24fps, 25fps, 30fps), preventing audio-video sync drift.
