Audio interface for recording vocals

A simple guide to choosing the right audio interface for vocal production with Mantra.

What is an audio interface?

An audio interface connects your microphone and instruments to your computer. It converts analog signals, like your voice, into digital audio that your DAW and Mantra can process.

You need an audio interface to connect an XLR microphone. Without one, you won’t be able to get high-quality audio into your system, power condenser mics with phantom power, or monitor your input with low latency.

This guide explains the key features to consider when choosing an interface and recommends a few reliable options that work well with Mantra.

Why do you need an audio interface for vocal recording?

To use an XLR microphone for vocal recording, you need an audio interface.

Built-in mics or USB mics can work for casual use, but they often lack the sound quality, control, and flexibility needed for proper vocal production.

An audio interface gives you:

The ability to connect professional XLR microphones
Cleaner recordings with higher resolution and lower noise
Phantom power for condenser microphones
Mic preamps to boost signal levels without distortion
Low-latency monitoring while recording

Features to consider when choosing an audio interface for vocals

Number of inputs and outputs

Inputs can include microphone, instrument (Hi-Z), or line-level sources. They typically come in XLR or 1/4" TRS formats. Outputs usually include connections for studio monitors and headphones.

If you are only recording vocals, a single XLR mic input is enough. If you also plan to record instruments or use multiple mics at the same time, look for an interface with more inputs.

If you want to monitor through more than one set of speakers or headphones, choose an interface with multiple output options.

Phantom power (+48V)

Phantom power is a type of electrical power that audio interfaces send through XLR cables to operate condenser microphones.

Most condenser microphones will not work at all without phantom power. Interfaces with phantom power typically have a +48V switch or button to enable it.

Make sure your interface includes this feature if you plan to use a condenser microphone.

Connectivity and compatibility

Most audio interfaces use USB-C, which is the current standard. You can connect them to older USB-A ports using a USB-C to USB-A cable, which many interfaces include.

The most important factor is whether the interface is compatible with your operating system (macOS or Windows) and works reliably with your DAW (Digital Audio Workstation). Nearly all major audio interfaces today are cross-platform and designed to work with the most common recording setups. Always check the manufacturer’s system requirements to ensure compatibility before purchasing.

Portability

If you record in different locations, consider a compact, bus-powered interface. Portable models are lightweight and travel-friendly but may offer fewer inputs and outputs.

Price

Audio interfaces can range from budget-friendly options under $100 to high-end options that cost thousands of dollars. Higher-end models offer more features and better audio quality, but even affordable options today can deliver excellent results.

Choose a model that fits your budget and has the features you need. All of the options below work well with Mantra.
