44.1kHz vs 48kHz: Which Sample Rate Should You Use?
Published on April 15, 2026
44.1kHz samples audio 44,100 times per second and is the standard for CDs and most music distribution. 48kHz samples 48,000 times per second and is the standard for video production, film, and broadcast TV. Both rates capture the full range of human hearing (up to about 20kHz), and neither sounds better than the other in a blind test. The choice comes down to what your final output medium is.
Why Two Standards Exist
44.1kHz was chosen for the Compact Disc in 1982. The number comes from the Nyquist theorem (you need at least 2x the highest frequency you want to capture) plus a small margin above 20kHz for the anti-aliasing filter. The exact value of 44,100 was tied to the video-based recording equipment used at the time. 48kHz became the professional audio standard for video because it divides evenly into common frame rates (24, 25, 30 fps). Film and broadcast settled on 48kHz, and it stuck.
Audio Quality Difference
In controlled listening tests, people cannot reliably distinguish 44.1kHz from 48kHz playback. Both rates exceed what human ears can detect. The Nyquist frequency for 44.1kHz is 22.05kHz, and for 48kHz it is 24kHz. Since most adults cannot hear above 16-18kHz, neither rate is a limiting factor. The quality of your microphone, preamp, room acoustics, and encoding bitrate matter far more than sample rate.
When to Use 44.1kHz
Use 44.1kHz when your final deliverable is music-only and will be distributed as CD, MP3, FLAC, or any streaming music format. Spotify, Apple Music, and most music platforms use 44.1kHz as their base sample rate. Recording at 44.1kHz avoids an unnecessary sample rate conversion step when you export for these platforms. If your entire chain is music, start and stay at 44.1kHz.
When to Use 48kHz
Use 48kHz when your audio will accompany video. This includes film scoring, podcast episodes with video versions, YouTube content, broadcast work, and game audio. Video editing software expects 48kHz by default. If you record at 44.1kHz and drop it into a 48kHz video timeline, the software will resample it, which can introduce subtle artifacts. Avoid the conversion by recording at 48kHz from the start when video is involved.
What About Higher Sample Rates?
96kHz and 192kHz exist mainly for recording and mixing headroom. They do not produce audible improvements in the final master. Some engineers prefer higher rates during tracking because the anti-aliasing filters can be more relaxed, but the final bounce is almost always 44.1kHz or 48kHz. Higher rates multiply file sizes proportionally and demand more from your CPU and storage.
