Abstract: In one example, a shared buffer acting as an audio communication channel for an audio interaction device may be reconfigured to allow audio communication channel sharing between audio data streams. An audio interaction device may execute a conversion between an initial audio data stream and an audio signal audibly detectable by a user. A shared buffer may act as an audio communication channel between an operating system and the audio interaction device. The digital audio system may execute an initial audio application with the operating system to process the initial audio data stream. The digital audio system may load the initial audio data stream into the shared buffer. The digital audio system may alter the audio communication channel into a restructured audio communication channel for a subsequent audio data stream while maintaining the initial audio data stream. The digital audio system may load the initial audio data stream into the restructured audio communication channel.
