An audio interface is a device that is responsible for the playback of your sound from your computer.
Do you know...Your computer comes preloaded with an audio interface, and it might be in your PC or a chip on your motherboard. That chip is responsible for making the sound you hear.
Without the interface, your computer or laptop will lack the function of being able to play a sound. Note: Audio Interface can also be called a soundcard or an external soundcard.
If your PC or laptop has an interface by default, then why do you need an external audio interface?
It doesn't have to be complicated!
This is the reason you might need one...
- You need an audio interface if you plan on recording live instruments or vocals.
- If you want to work with a professional quality microphone (XLR), or professional hardware, then you need an external audio interface.
- If you wish to properly plug in a balanced input or a good pair of studio monitors to check your mixes on, without an interface, you won't have anywhere to plug those in.
