The computer should be able to recreate waves with frequencies up to 20 kHz in order to preserve everything we can hear. However, this вЂњ20-to-20вЂќ 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 kHzвЂ“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 youвЂ™ll see is 44.1 kHz, or 44,100 samples per second. Why is the standard audio sample rate 44.1 kHz? Early filters could taint the audio, but this problem is being minimized as better technology is introduced. This will prevent unwanted super-high frequencies in the original audio from causing aliasing. To prevent aliasing, audio-to-digital converters are often preceded by low-pass filters that eliminate frequencies above the Nyquist frequency before audio reaches the converter.

Signal above the Nyquist frequency is not recorded properly by audio-to-digital converters (ADCs), becoming mirrored back across the Nyquist frequency and introducing artificial frequencies in a process called aliasing. Conversely, a system can capture and recreate frequencies up to half the audio sample rate, a limit called the Nyquist frequency. This means we can capture and reconstruct the original sine waveвЂ™s frequency with an audio sample rate at least twice its frequency, a rate called the Nyquist rate. 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?Дigital audio is the system in which we store, recreate, and manipulate audio information in a computer system. ItвЂ™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, weвЂ™ll focus on audioВ sample rate and audioВ bit depth, as well as a few topics related to them. In this article, weвЂ™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 didnвЂ™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.Д®ven bouncing my first track was confusing.

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