Things to Consider

The vast world of audio recording can appear quite complex, especially if you’re a newcomer. One of the key components of any recording setup is the audio interface, a device that might seem straightforward but in reality, has many nuanced aspects to consider. In this guide, we will take a deep dive into the intricacies of audio interfaces, particularly those with USB-C connectivity, to assist you in finding the ideal match for your recording needs.

The Role of Audio Interfaces

An audio interface is a hardware device that serves as a conduit between your recording instruments—be it microphones, guitars, keyboards—and your computer. Its primary function is to convert the analog signals from your instruments into digital signals that your computer can process and vice versa. In simpler terms, it’s a box that lets your computer understand the “language” of your instruments and ensures your recorded audio sounds are as clean and professional as possible.

Audio interfaces like the RME Babyface Pro FS or the Audient iD4 MKII provide a range of features and connections, allowing you to tailor your recording setup to your unique requirements. The choice of interface can drastically affect the quality of your recorded sound, the ease of your recording process, and the overall capabilities of your setup.

The Significance of Inputs and Outputs (I/O)

The number and type of inputs and outputs an audio interface possesses are crucial aspects that directly dictate its compatibility with your recording setup. Depending on the complexity of your recording needs, the required number of inputs can vary.

For instance, if you’re in a band and plan to record multiple instruments simultaneously, you’ll need an interface that can handle multiple inputs. The Focusrite Clarett 2Pre, boasting a multitude of I/O options, can facilitate this. Conversely, the need for numerous inputs lessens if you’re a solo artist or podcaster. An interface like the Audient iD4 MKII, which offers fewer but high-quality I/O options, may suit you perfectly.

Additionally, the outputs of your interface can play a pivotal role in monitoring your audio. You’ll want enough outputs to connect your studio monitors and headphones and possibly send audio to external hardware effects.

The Importance of Audio Quality

The key goal of any recording process is to capture high-quality audio. The role of the audio interface in achieving this goal is indispensable. The audio quality an interface can provide is generally determined by two crucial aspects: bit depth and sample rate.

In layman’s terms, bit depth relates to the dynamic range of your audio—the difference between the loudest and softest parts of a sound—while sample rate refers to the detail with which your audio is captured. Higher bit depth and sample rate lead to richer and more detailed audio.

The good news is that all our reviewed interfaces, from the MOTU M2 to the Steinberg UR22C, offer professional-standard high-resolution audio, ensuring your recordings carry the depth and detail needed to stand out.

Durability and Build Quality Matter

The robustness and overall build quality of your audio interface can be a key deciding factor, especially if you frequently travel with their recording setup.

Take the Apogee Duet 3, for instance. This device has made a name for itself due to its stellar audio quality and its robust and compact design. Its durability makes it an excellent companion for artists who often find themselves on the road, ensuring your recording process remains uninterrupted, regardless of location.

Recognizing the Value of Additional Features

While the core function of an audio interface is to convert analog signals into digital (and vice versa), modern interfaces often come equipped with an array of additional features designed to make your recording experience more convenient and versatile. These can range from built-in effects to bundled software suites.

The RME Babyface Pro FS, for instance, comes bundled with the TotalMix FX software, granting users an extra degree of control over their mix. Similarly, the MOTU M2 features loopback functionality, making it particularly handy for live streaming or podcasting scenarios.

How to Use an Audio Interface

Setting up and using an audio interface is typically a straightforward process. However, the exact steps can vary depending on the specific model and your individual recording setup. Here’s a simplified step-by-step guide:

  1. Connect your audio interface to your computer using the USB-C cable.
  2. Install any necessary drivers or software that come with your interface. This could be something like the TotalMix FX software included with the RME Babyface Pro FS.
  3. Connect your microphones or instruments to the inputs of your audio interface. Depending on the device, you might need XLR cables for microphones or 1/4″ cables for guitars or keyboards.
  4. If you’re using studio monitors, connect these to the output of your interface.
  5. Open your preferred audio recording software (also known as a DAW – Digital Audio Workstation) and select your audio interface as the input and output device. This tells the software to use your interface for all audio recording and playback.
  6. Test your setup by recording some audio. You should be able to adjust input levels directly on the audio interface to ensure your sound isn’t too loud (which can cause distortion) or too quiet (which may result in background noise).

Remember, each audio interface will have its unique quirks and specificities, so always refer to the user manual or manufacturer’s instructions for the most accurate information.

By now, you should be better equipped with the knowledge needed to make an informed decision when purchasing your next USB-C audio interface. Consider your specific recording requirements, the instruments you’ll be using, and the environment you’ll be working in. Whether it’s the robustness of the Apogee Duet 3 or the multifaceted capabilities of the RME Babyface Pro FS that appeal to you, the ultimate goal is to find a tool that will help you capture your creative impulses in the highest fidelity possible.



Yes, USB-C 2.0 supports audio. The USB-C format allows for data transfer as well as audio signal transmission. It can handle the data bandwidth required for multi-track audio, making it a popular choice for audio interfaces.

The length of a USB-C cable for an audio interface can affect signal transmission quality. For optimal performance, it is recommended to use a USB-C cable less than 3 meters (about 10 feet) in length. Using a longer cable might result in a degradation of signal quality due to increased latency.

Indeed, USB-C 3.1 supports audio. It actually offers better performance than USB-C 2.0 due to its higher data transfer speed. USB-C 3.1 can provide a more stable and faster connection for audio interfaces, ensuring excellent audio quality without latency issues.

USB-C offers several advantages for sound, particularly in terms of power delivery and high-speed data transfer. It supports multi-channel audio formats and delivers superior sound quality. However, the actual sound quality will depend on other factors as well, such as the design of the audio interface and the quality of the audio source.

Thunderbolt, especially Thunderbolt 3 and 4, can provide faster data transfer speeds than USB-C, which can benefit audio interfaces requiring high bandwidth. However, this doesn’t necessarily mean Thunderbolt is “better” than USB-C. Both have their merits and are well suited for professional audio applications. It’s crucial to consider the compatibility of your devices and your specific requirements before making a decision.
