The math can get very complicated very quickly. This limited resolution, of course, introduces some error – known as quantization error. In our example above, we are using a very low resolution of 3 bits, which means we can show only eight different levels. To encode a value using this format, we simply assign a 1 or a 0 to each placeholder such that the sum values represented by the placeholders with a 1 represent the original value. The second space is 2 to the power of 1, which is 2, the next space is 2 to the power of 2 which is 4, and so on. So, the first space is 2 to the power of 0, which is 1. Each space in a digital word represents a value of 2 to the power of the location. Counting in DigitalĬounting in digital is easy, once you understand how it works.

If we increase the voltage to 0.8 volts, we trigger all but the last two switches and get the word 0110 (which is 6).

If we feed an analog signal into our comparator switch tree with a level of 0.3 volts, the bottom two switches will turn on, and we get the digital word 0010 (which is 2). We’ll keep the example simple and say that we have eight switches, each of which is triggered atĠ.125-volt increments.

Imagine, if you will, a series of comparator switches, each stacked one atop the next and referenced to an ever-increasing voltage. They are incredibly compact and, relative to when they were first introduced, inexpensive.ĪDC work in several ways, but we’ll describe the basics.

These devices are commonplace and are found connected to the microphone in your smartphone or the Bluetooth microphone in your car. How Are Digital Audio Files Created?Ī device called an analog-to-digital converter (ADC) is responsible for taking the analog signal and converting it into a digitally represented value. To calculate how much space it would take to store a song like “Bohemian Rhapsody” by Queen, you can simply multiply 1,411,200 by the number of seconds in the song (in this case, 355 seconds) for a total of 500,976,000 bits, or about 60 megabytes of data. Since we sample the audio signal at 44,100 times a second, and each sample has a voltage level represented by a 16-bit word, and we do this for two channels, 44,100 times 16 times two is 1,411,200, or 1.411 kilobits per second. Some Quick Math on CD Quality Audioįor those interested, it’s easy to calculate the effective bitrate of a CD-quality audio file. That’s a lot of detail.įinally, the Red Book standard states that two channels of audio will be sampled simultaneously to create a stereo recording. If you are converting the output of a microphone to digital, and the maximum voltage is 1 volt, then a resolution of 16 bits means that the resolution is 0.000015258789 volts. This means that there is a string of 16 1’s and 0’s that can be used to represent 65,536 voltage levels. The Red Book standard uses a digital word length of 16 bits. The second consideration in converting an analog signal to the digital domain is the need to store an adequate amount of resolution to properly represent the original signal. To capture the entire audible spectrum of sound, the Nyquist-Shannon sampling theorem states that the sampling rate needs to be at least twice as high as the highest frequency you want to record for it to be recreated with accuracy. The sampling rate describes how often a voltage level is measured and stored. In the digital domain, i.e., a computer, information can be stored as a 1 or a 0.Ĭomputers can combine strings of 1s and 0s to represent characters in a text document, colors in a photograph, commands in a program or voltage levels in an audio file.įor decades, the standard for storing audio in the digital domain has been the Red Book Compact Disc Digital Audio (CD-DA) standard of a 44.1kHz sampling rate with a depth of 16 bits. In the simplest of terms, a digital audio file is a representation of an analog signal using a series of digital words. In this article, we are going to look at how digital audio works and dispel some of the myths around the conversion between the analog and digital domains. Between 19, the compact disc entered the market and forever changed the way music was stored and transported. If you are in your late 40s or older, then you likely grew up with a turntable or tape player in your home as a way of listening to store-bought music.
