If you've ever exported an audio file, you've probably seen numbers like 44,100 Hz (44.1kHz) or 48,000 Hz (48kHz). But what do they actually mean? And does it matter which one you choose?
While sound engineering can get very technical, understanding sample rates doesn't have to be. Here's a simple breakdown of what they are and which one you should use for your next project.
What is a Sample Rate?
Think of it like the "frame rate" for video. In video, 24 or 60 frames per second create a smooth-looking image. In audio, the "sample rate" is the number of times per second your computer "takes a snapshot" of the sound wave. The higher the number, the more accurate the digital representation of the sound.
The Standard: 44.1kHz
This has been the standard for music ever since the invention of the Compact Disc (CD). It's balanced, widely supported, and captures everything humans can realistically hear. If you're creating music or a pure audio podcast, 44.1kHz is almost always the right choice.
The Professional Standard: 48kHz
This is the standard for anything involving video—YouTube Shorts, TV shows, and movies all use 48kHz. It's slightly more "hi-res" and aligns better with the timing of video frames. If your audio is going to be part of a video, 48kHz is the way to go.
Does It Affect Sound Quality?
Honestly? For most listeners, the difference between 44.1kHz and 48kHz is imperceptible. Unless you're using professional studio monitors in a perfectly quiet room, you likely won't hear any difference. The main reason to choose one over the other is compatibility.
Which Should You Choose on OnlineAudioEdit?
Our editor typically matches the sample rate of your input file. If you're exporting for social media, choose 48kHz if possible for better integration with video algorithms. For music, stick to 44.1kHz.
