The invention relates to a method and adaptive system for multichannel audio distribution between at least one stereo audio source (SA1, SA2, SA3, SA4) and at least one playback device (EP, EA), such as a passive or active loudspeaker. The system comprises a hub (H) capable of receiving stereo audio (ST) content from at least one audio source (SA1, SA2, SA3, SA4), and at least one linking device (L1, L2) connected by wire to a playback device (EP, EA). The hub (H) is capable of converting any stereo content (ST) into a set of spatialized audio streams, each stream being associated with and transmitted to a corresponding linking device (L1, L2) according to a predetermined playback configuration, while the linking device (L1, L2) provides the loudspeaker with the spatialized audio stream it receives from the hub (H) for playback. To this end, the preferred communication protocol between the concentrator (H) and each link (L1, L2) is the WISA protocol.Figure from the summary: Fig. 1.

Systems and methods are provided for multichannel content remix. A flow is defined for generating new content based upon source content. The flow is defined with nodes arranged according to a graph structure such that downstream nodes utilize output from upstream nodes as input. An execution engine processes each node of the flow by identifying an executor associated with a node type of a node. If the node is a downstream node, then an output of an upstream node is used to as input for the downstream node.The node is executed to generate a prompt that is input into a machine learning model to create a node result for the node. Once the execution engine has processed the nodes of the graph structure, the node results are used to generate the new content that is provided through a content provider channel.
