Why do I need an audio interface?

As your music knowledge grows and your music journey continues, you will most likely ask your self “Why do I need an audio interface”? A lot of people ask this question as well when they realize that they can make music easily on their laptop or computer with their DAW of choice. Let’s explore the question further.

Why do I need an audio interface?

The reason why you need an audio interface is because of these following reasons:

  • I need to record vocals
  • I need to record my guitar or other external instrument
  • I want to have a CLEANER sound
  • I want to connect studio monitors my computer
  • I want to mix and/or master songs
  • I want to become a more advanced music producer

There are probably more but these are pretty much the main reasons. Let’s look into each and dissect them even further!

I need to record vocals

If you want to record vocals then there is no doubt an interface is needed.

Wait… hold up.. I just received a message from the USB mic community: “No you are WRONG. Im getting along fine with my USB mic so no audio interface is needed!” . Okay let me explain… Yes they are 100 percent right but a USB mic simply does not have the same power and features as a mic that is connected via XLR cable to an audio interface, like a condenser microphone.

If you want professional sounding vocals then a microphone like a condenser microphone is needed and in order to connect a condenser microphone to your computer, you need an interface.

I need to record my guitar or other external instrument

Let’s say you are in Fl Studio and you are making a nice beat. You then decide, “I want to record my guitar” because this riff I just did sounds really nice! Depending on the type of guitar this is, you will need a 1/4in cable that goes from your guitar in to your audio interface, or a nice microphone to record the raw guitar sound… like you would a vocal.

Same thing goes for any external instrument that you want to record into your computer. You will need the necessary wires or mic set up to make that happen and that will go straight to your audio interface.

I want to have a CLEANER sound

I’ll just say it bluntly – Most on board sound cards/chips on computers and laptops are TRASH.

To be frank, most computer companies don’t really care too much about how on board audio from your computer sounds. I’ve had computers where the sound was so bad that it prevented me from making music for a while. I knew that this wasn’t my limit and I could actually get sound that sounds great like the PROS. I went out and purchased an interface and never looked back… in fact if you are a serious musician, then an interface is necessary.

The sound that comes out of an audio interface is just CLEAN. It sounds so good and you are able to hear how your music sounds in HIGH QUALITY.

Producing through an interface also helps you make better decisions because you can easily hear all the details of your music and find out what it needs or doesn’t need.

I want to mix and/or master songs

If you want to mix and/or master yours or a client’s songs, then with out question an interface is needed.

The reason for this is because, when you are engineering a track, you need to have a clear high definition picture of what is going on in the song. You can not afford to cross your fingers and hope that everything sounds good if you are mixing without an audio interface.

All the respectable mixing and mastering engineers in the world all make use of an interface and it shows in their work.

Your favorite songs were all mixed on one so there is no excuse to not go out and pick up an audio interface of your choice.

I want to become a more advanced music producer

So let’s say you have been making beats without an audio interface and record your vocals via a USB Mic. At one point you will feel like you have plateaued. You wont be able to escape this feeling because if you are passionate about music; your gut feeling will straight up tell you that it’s time to improve as a musician. Having an audio interface is the quickest way to advance in your music journey.

When you have an audio interface, it forces you to think differently. It forces you to understand music from a different angle and become even more technical about music (this is not a bad thing!).

You will take your recordings, production, mixes and masters more seriously and your music will thank you for it as well.
