Audio sample rate

The audio sample rate is a measurement of the samples per second taken by the system from a continuous digital signal; these frequencies are measured in kilohertz (kHz). The audio sample rate determines the range of frequencies captured in digital audio.

What is best audio sample rate?

44.1kHz is the most common sample rate for music CDs. It captures the entire audible frequency spectrum accurately. This sample rate is ideal because it won't use much disk space or more CPU power. Yet it will still deliver the authentic sound you need for your professional recordings.

Should my sample rate be 44.1 or 48?

For most music applications, 44.1 kHz is the best sample rate to go for. 48 kHz is common when creating music or other audio for video. Higher sample rates can have advantages for professional music and audio production work, but many professionals work at 44.1 kHz.

Is 192kHz a good sample rate?

For mastering, 96kHz or even archival mastering at 192kHz is usually a good idea. Regardless, recording at 44.1 or 48kHz through a high-quality modern audio interface will give you excellent results, depending on the situation, very similar to what you'd get at higher rates.

Why is audio sampled at 44.1 kHz?

According to the Nyquist theorem, 44.1 kHz allows reproduction of all frequency content below 22.05 kHz. This covers all frequencies heard by a normal person. Though there is still debate about perception of high frequency content, it is generally agreed that few people can hear tones above 20 kHz.
