Choosing an Audio Interface for Live Streaming

The Role of the Audio Interface in a Streaming Setup

Just as a high-quality webcam and proper lighting contribute to a polished streaming experience, the significance of audio quality cannot be overstated. For those entering the world of streaming, enhancing your audio quality is a cost-effective and straightforward step, achievable through investing in an audio interface.

If you’ve been exploring the essentials for a modular and long-term streaming setup, chances are you’ve encountered discussions about audio interfaces. In simple terms, an audio interface transforms analog signals, such as those from XLR-connected microphones, into a digital format compatible with your computer. This conversion process allows streamers to seamlessly integrate analog equipment into software like OBS. By circumventing your computer’s internal sound card, the audio interface takes on the role of processing audio, offering benefits such as latency-free monitoring—an invaluable feature for maintaining synchronization in your live broadcasts.

How to Choose an Audio Interface for Live Streaming

Choosing the right audio interface for your live streaming setup is a critical decision that can significantly impact the quality of your audio. A popular entry-level interface among streamers is the Focusrite Scarlett 2i2. This interface provides a balance between affordability and performance, making it an excellent choice for those just starting in the world of live streaming.

If you only need to record a single signal, it might be wise to spend your money on an audio interface that provides good preamps instead of multiple input and output channels. The Elgato Wave XLR is a prime example. While it features only a single XLR input, it boasts up to 75 dB of ultra-low-noise gain. This capability allows it to amplify even insensitive microphones like the Shure SM7B, making it a valuable investment for streamers focusing on solo performances or commentary.

It’s important to note that the purchase of an audio interface isn’t necessary when choosing a USB microphone. USB microphones have built-in analog-to-digital converters, eliminating the need for an external audio interface. In such cases, streamers might opt to allocate their budget toward acquiring a higher-quality USB microphone, enhancing their audio setup without the additional expense of an audio interface. Consider your specific streaming needs and equipment requirements when making this decision, ensuring that your investment aligns with your goals for achieving optimal audio quality in your live streams.
