Exploring audio integration in live streaming setups is crucial for creating a high-quality viewer experience. This overview covers various methods and equipment for incorporating audio into your video stream, focusing on practical solutions for different switcher types and production scales.

Blackmagic Switcher Audio Integration

Blackmagic switchers offer a convenient built-in solution for audio input, setting them apart from many competitors. These switchers typically include:
  • Two analog audio inputs for direct connection from a front-of-house console
  • The ability to set audio output on your program feed through ATEM software control
This feature eliminates the need for additional hardware, streamlining your setup and potentially reducing costs. It's a significant advantage if you're considering Blackmagic for your streaming needs.

Audio Embedders for Non-Blackmagic Setups

If you're using a different brand of switcher or need to integrate audio with an existing setup, an audio to SDI embedder might be necessary. These devices:
  • Take in separate audio and video signals
  • Combine them into a single SDI feed
  • Output a unified audio-video signal ready for your streaming encoder
This approach ensures your audio and video are synchronized on the same line, which is essential for professional-quality streams.

Pro Tips for Audio Routing

Here's a clever way to maximize your setup's flexibility:
  • Output the combined audio-video signal from your embedder to an open input on your switcher
  • This creates a routable program feed with audio
  • Useful for sending audio-inclusive feeds to different destinations (e.g., lobby displays)
While it's possible to stream using just a camera's onboard mic, this often results in unbalanced audio. Integrating front-of-house audio through a switcher or embedder allows for more control and better overall sound quality, enhancing the viewer experience significantly.
