To play background music in real-time audio and video (TRTC), you typically need to integrate an audio mixing or processing feature into your application. This allows you to overlay background music onto the live audio stream of a user without completely replacing it.
Here's a basic approach to achieve this:
Audio Mixing: Use an audio mixing library or API to blend the background music with the user's voice. This ensures that both sounds are heard clearly without one overpowering the other.
Volume Control: Implement volume control for the background music so that it doesn't interfere with the clarity of the primary audio (user's voice). You might want to lower the volume of the background music when the user is speaking and increase it during pauses.
Synchronization: Ensure that the background music is synchronized with the video stream. This means starting and stopping the music in coordination with the video playback.
Example: Imagine a live streaming app where users can broadcast games. To enhance the experience, you want to add a background track of game sound effects or music. Using TRTC, you can mix this background audio with the user's voice chat. When the user speaks, the system reduces the volume of the background music to ensure their voice is clear. When the user stops speaking, the background music volume increases slightly to maintain an engaging atmosphere.
For implementing such features in a cloud-based solution, you might consider services that offer real-time audio processing capabilities. For instance, Tencent Cloud's Real-Time Communication (TRTC) service provides APIs and SDKs that can be used to develop applications with real-time audio and video features, including audio mixing and processing. This can help in seamlessly integrating background music into your live streaming applications.
