Frequently Asked Questions
Do I need to buy expensive software to use these interfaces?
Not at all. Most budget interfaces come bundled with entry-level recording software, often called a Digital Audio Workstation or DAW. These versions are fully functional and perfect for starting your first project. You can also find plenty of free professional-grade software online. You are paying for the hardware, and the software is usually a helpful bonus to get you running immediately.
Can I plug my guitar directly into these devices?
Yes, most interfaces under 100 feature a Hi-Z or instrument switch on the input. This setting changes the electrical impedance to match the signal from your electric guitar or bass. If you skip this step, your guitar will sound thin and dull. Using the correct input setting keeps your tone thick and punchy.
Will these interfaces work with my iPad or smartphone?
Many modern interfaces are class-compliant, which means they work with mobile devices without needing extra drivers. You might need a camera connection kit or a powered USB hub to provide enough electricity. Check the manufacturer website for a compatibility list. It is a great way to record high-quality audio on the go using mobile apps.
Why is there a delay when I record?
That delay is called latency, and it happens when your computer takes too long to process the signal. You can usually fix this by lowering your buffer size in your recording software settings. A smaller buffer size reduces the delay but puts more strain on your computer processor. Finding the right balance is a small puzzle you solve once, and then you can record comfortably.
How do I know if my microphone is compatible?
As long as your microphone uses an XLR cable, it will work with almost any interface. If your microphone has a built-in USB cable, you cannot plug it into an audio interface. Those USB microphones are designed to work by themselves. An interface is strictly for microphones that output an analog signal through a standard three-pin connection.
