Introduction.

An audio interface is an essential part of DTM. It is an indispensable tool for producing songs, mixing, mastering, recording guitar and vocals, live streaming on video distribution sites, and many other things.
However, with so many audio interfaces available from various companies, it can be difficult to know which model or manufacturer to choose.
Therefore, in this article, we will introduce recommended audio interfaces so that beginners can choose an audio interface with ease.
Please take a look at them for reference.
What is an audio interface?
An audio interface is a piece of equipment that converts an analog signal such as the sound of a guitar, bass, or other musical instrument or vocal sound into a digital signal to be input to a computer, or converts a digital signal into an analog signal to be output to a speaker.
An audio interface can amplify and input low output sounds such as guitars.
This allows the sound to be recorded louder.
This reduces the amount of noise and makes it possible to record in an easy-to-hear quality.
10 recommended audio interface companies

The iPhone/iPad is also a full-fledged music production software and hardware product for iOS devices.
The iPhone/iPad is now recognized as an environment that can be used for serious music production, and IK Muitimedia has had a tremendous impact on that.
AXE I/O
Many audio interfaces have a feature called Hi-Z input (high-impedance input). By using this Hi-Z input, you can record your guitar without sound fading.
High-impedance means that low-impedance signals from guitars, basses, and other instruments can be input into the Hi-Z input to prevent deterioration of sound quality by creating a “low send, high receive” configuration.
However, the Hi-Z input on an audio interface is not sufficient for this purpose. The AXE I/O is an audio interface developed specifically for guitars.
It features 2 IN/5 OUT (including AMP OUT), a Z-TONE guitar input with 3 different topologies, 2 balanced + 2 unbalanced line outs, a reference headphone out, and 2 freely assignable controller inputs.
Because it is made specifically for guitar, it has a dynamic range of 117 dB and a frequency response that covers a wide range of frequencies from 3 Hz to 32 kHz, allowing for very clear, high-quality guitar recording.
summary
- An audio interface is a device that converts analog signals into digital signals.
- It is a must for mixing, mastering, vocal recording, guitar and bass recording.
- Use an audio interface from a company you like.
- An audio interface with built-in DSP does not put a load on the CPU of your computer.
