Audio balancing for multi-source audiovisual streaming

A method for broadcasting game audio and video with user audio and video using a computing device, the method comprising:

• receiving a microphone audio stream generated by a microphone at a microphone input level;
• receiving a game audio stream generated by a game program executed at the computing device at a game input level;
• presenting a graphical user interface via a display device, the graphical user interface including an audio mix control element;
• receiving a user input directed at the audio mix control element;
• identifying an audio mix setting responsive to the user input;
• resampling one or more of the microphone audio stream and/or the game audio stream to a common sample rate for both the microphone audio stream and the game audio stream;
• adjusting one or more of the microphone input level and/or the game input level, following resampling to the common sample rate, based on the user-selected audio mix setting to produce rebalanced microphone and game audio streams;
• multiplexing the rebalanced microphone and game audio streams to produce a multiplexed audio stream following one or more of the microphone audio stream and/or the game audio stream being resampled to the common sample rate;
• encoding, via an audio encoder, the multiplexed audio stream to produce an encoded audio stream;
• receiving a camera video stream generated by a camera or a game video stream generated by the game program executed at the computing device as a component of an input video stream;
• encoding, via a video encoder, the input video stream to produce an encoded video stream;
• packaging encoded audio and video streams into one or more streaming packets;
• and
• outputting the one or more streaming packets.

A computing system for streaming of multiple sources of audio and video, the computing system comprising:

• one or more logic machines configured to:
• execute a game program;
• receive a game audio stream generated by execution of the game program at a game input level;
• receive a microphone audio stream generated by a microphone at a microphone input level contemporaneously and in parallel with the game audio stream;
• resample one or both of the microphone audio stream and the game audio stream to a common sample rate for both the microphone audio stream and the game audio stream using software-based conversion of incoming audio samples of an input sample rate to the common sample rate;
• adjust one or both of the microphone input level and the game input level, following resampling to the common sample rate, based on a user-selected audio mix setting to produce rebalanced microphone and game audio streams;
• multiplex the rebalanced microphone and game audio streams to produce a multiplexed audio stream following one or both of the microphone audio stream and/or the game audio stream being resampled to the common sample rate using software-based multiplexing that is prioritized over resampling of the microphone and/or game audio streams;
• encode, via an audio encoder, the multiplexed audio stream to produce an encoded audio stream;
• receive a camera video stream generated by a camera;
• receive a game video stream generated by the game program contemporaneously and in parallel with the game audio stream and the camera video stream;
• composite the camera video stream and the game video stream to produce a composited video stream;
• encode, via a hardware-specific video encoder, the composited video stream to produce an encoded video stream;
• package the encoded audio and video streams into one or more streaming packets;
• initiate a socket connection to a remote computing device;
• and
• send the one or more streaming packets to the remote computing device via the socket connection.
