Abstract: Real-Time Separation And Synchronized Routing of Vocal And Instrumental Streams To Distinct Devices The present invention relates to audio signal processing. Conventional audio systems face technical problems of high processing latency and an inability to route different audio components of a single track to separate devices in synchrony. The present invention provides a system and method for real-time, on-device audio source separation and synchronized multi-device routing. The system receives a composite audio stream, segments it into chunks, and applies a neural network to separate it into vocal and instrumental stems. A routing module directs the vocal stem to a first output device and the instrumental stem to a second, distinct output device. A synchronization engine determines output-device latency characteristics and applies temporal compensation to substantially synchronize playback. This enables low-latency, interactive audio experiences, such as karaoke, by routing synchronized vocal and instrumental streams to separate playback devices. Refer FIG. 1
