Noise in Audio Interfaces

Every component in a digital audio production process generates noise, and audio interfaces are no exception. The key contributors to noise in audio interfaces are ADC/DAC processors, pre-amps, and circuitry. Each of these generates noise in unique ways that are important to understand when managing a digital audio workflow.

What Causes Noise in Electronic Circuits?

Every electronic circuit generates noise due to its inherent physical properties and the nature of flowing electric charges. In audio applications, devices like audio interfaces produce noise from the electronic components they’re made from. Such noise is unavoidable, but keeping noise to a minimum is important in an audio workflow.

How ADC Works: An Introduction to Sampling

Analog-to-digital conversion, or ADC, is a fundamental part of the digital audio workflow. Audio interfaces are dedicated devices that specialize in ADC. Although there are various approaches to ADC, they all rely on the process of sampling. In this article, we’ll look at the basics of sampling, how it works, and the key parameters associated…

What is ADC in an Audio Interface?

One of the main functions of an audio interface is to convert sound from physical instruments or microphones (analog) to a form that computers can process (digital). This is called analog-to-digital conversion, or ADC. It is a necessary part of the digital audio workflow.

Why Latency Matters: How an Audio Interface can Help

In an audio production environment, latency refers to the time taken for an audio signal to travel through, and be processed by, an audio workflow. Latency matters because when it gets too large it becomes noticeable and hinders the production process. Fortunately, a good audio interface can help to reduce latency.
