No offense.

First, you need to download cross talk audio files from major music platforms, and then open the live broadcast interface. Then you need to set the cover and title of the live broadcast, and select the "Voice Live Broadcast" mode to open the live broadcast room. You can set up the cross talk playback.

Click the voice button in the lower left corner of the live broadcast room page, enter the music library page and select the "Local" category. You will be able to find the cross talk audio files you have downloaded and add them to the live broadcast room for playback.
