What is an audio interface and how does it work?
An audio interface is a device that connects your microphones or instruments to your computer, allowing you to record high-quality audio. It works by converting the analog audio signal from your microphone or instrument into a digital signal that your computer can understand. This process is called analog-to-digital conversion, and it’s essential for recording audio on a computer.
The audio interface sends the digital signal to your computer via a USB or Thunderbolt connection, where you can record and edit it using recording software. The interface also allows you to monitor the audio signal in real-time, so you can hear what you’re recording as you’re recording it. This is useful for catching any mistakes or issues during the recording process.
Do I need an audio interface to record audio on my computer?
Not always. If you’re using a computer with a built-in microphone or a USB microphone, you can record audio without an audio interface.
