This sample rate moves the Nyquist frequency to around 24 kHz, giving further buffer room before filtering is needed. For instance, it’s the standard sample rate in audio for video.
The higher sample rate technically leads to more measurements per second and a closer recreation of the original audio, so 48 kHz is often used in “professional audio” contexts more than music contexts. Moving the Nyquist frequency even higher allows us to place the filter further and further out of human hearing, and therefore impacts the audio even less.Ĥ8 kHz is another common audio sample rate. Some were introduced during the early days of digital audio when powerful anti-aliasing filters were expensive. While 44.1 kHz is an acceptable audio sample rate for consumer audio, there are instances in which higher sample rates are used. Other audio sample rates: 48 kHz, 88.2 kHz, 96 kHz, etc. By placing the Nyquist frequency outside of our hearing range, we can use more moderate filters to eliminate aliasing without much audible effect. The sample rate of 44.1 kHz technically allows for audio at frequencies up to 22.05 kHz to be recorded. This is true, but you need a pretty powerful-and at one time, expensive- low-pass filter to prevent audible aliasing. Therefore, a sample rate of 40 kHz should technically do the trick, right? The computer should be able to recreate waves with frequencies up to 20 kHz in order to preserve everything we can hear. However, this “20-to-20” rule is still accepted as the standard range for everything we could hear. Most people lose their ability to hear upper frequencies over the course of their lives and can only hear frequencies up to 15 kHz–18 kHz. Humans can hear frequencies between 20 Hz and 20 kHz. This is the standard for most consumer audio, used for formats like CDs. The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second.
Why is the standard audio sample rate 44.1 kHz? If we can take tons of measurements extremely quickly with enough possible amplitude values, we can effectively use these snapshots to reconstruct the resolution and complexity of an analog wave. The system makes thousands of measurements per second. This information is then converted into digestible, binary data.
A sample is taken at a particular time in the audio wave, recording amplitude.

The sound wave is converted into data through a series of snapshot measurements, or samples. This allows us to manage, edit, and arrange audio in a software-based context.

Certain characteristics of an analog sound wave, like the frequency and amplitude, are converted to data computer software can read. What is digital audio?ĭigital audio is the system in which we store, recreate, and manipulate audio information in a computer system. It’s a bit of theory and a bit of math, but hopefully it will peel away some of the mystery behind how digital audio works. Today, we’ll focus on audio sample rate and audio bit depth, as well as a few topics related to them. In this article, we’ll cover some basic aspects of digital audio, and how they affect the production process. What does each of the options do? How was I supposed to know what would sound best? Unfortunately, in the chaos of beginning to produce, I didn’t learn the basics of how a computer actually handles audio, so the whole concept of making music on a laptop felt a bit abstract.Įven bouncing my first track was confusing.

The arrangement possibilities were endless, and I could learn how to mix music to sound like what I heard. I remember how eager I was to get into music production.
