Optimizing audio signal networks using partitioning and mixer processing graph recomposition

A computer program product comprising:

• a non-transitory computer-readable medium with computer program instructions encoded thereon, wherein the computer program instructions, when processed by a computer system instruct the computer system to optimize a property of an audio signal processing graph comprising a plurality of nodes, the optimization comprising:
• receiving information specifying:
• for each audio input node of the graph, a locale that includes the audio input node;
• for each audio output node of the graph, a locale that includes the audio output node;
• and
• for each processing node of the graph, one or more supported locales for the processing node, wherein each of the one or more supported locales for the processing node includes at least one of a hardware and a software module capable of performing audio processing required by the processing node;
• for each processing node of the graph for which the received information specifies a plurality of supported locales, automatically determining an optimal supported locale from among the plurality of supported locales for the node;
• and
• automatically recomposing the audio signal processing graph to assign each of the processing nodes for which the received information specifies a plurality of supported locales to the optimal supported locale for that node, wherein the assignment results in an audio signal processing graph that minimizes at least one of:
• a number of inter-locale connections required to connect the plurality of nodes of the graph;
• and
• a latency between a specified input node and a specified output node.

A system comprising:

• a memory for storing computer-readable instructions;
• and
• a processor connected to the memory, wherein the processor, when executing the computer-readable instructions, causes the system to optimize a property of an audio signal processing graph comprising a plurality of nodes, the optimization comprising:
• receiving information specifying:
• for each audio input node of the graph, a locale that includes the audio input node;
• for each audio output node of the graph, a locale that includes the audio output node;
• and
• for each processing node of the graph, one or more supported locales for the processing node, wherein each of the one or more supported locales for the processing node includes at least one of a hardware and a software module capable of performing audio processing required by the processing node;
• for each processing node of the graph for which the received information specifies a plurality of supported locales, automatically determining an optimal supported locale from among the plurality of supported locales for the node;
• and
• automatically recomposing the audio signal processing graph to assign each of the processing nodes for which the received information specifies a plurality of supported locales to the optimal supported locale for that node, wherein the assignment results in an audio signal processing graph that minimizes at least one of:
• a number of inter-locale connections required to connect the plurality of nodes of the graph;
• and
• a latency between a specified input node and a specified output node.

A method of optimizing a property of an audio signal processing graph comprising a plurality of nodes, the method comprising:

• receiving information specifying:
• for each audio input node of the graph, a locale that includes the audio input node;
• for each audio output node of the graph, a locale that includes the audio output node;
• and
• for each processing node of the graph, one or more supported locales for the processing node, wherein a locale that is supported for the processing node includes at least one of a hardware and a software module capable of performing audio processing required by the processing node;
• for each unassigned processing node of the graph for which the received information specifies a processing node that is supported by both a first locale that includes a general-purpose computing system hosting a DAW application and a second locale that includes an audio processing device, automatically determining an optimal one of the first and second locales to which the node is to be assigned in order to optimize the property of the graph;
• and
• automatically recomposing the audio signal processing graph to assign each of the unassigned processing nodes to their respective optimal nodes, wherein the assignment results in an audio signal processing graph that is optimized for at least one of:
• a latency between a specified input node and a specified output node;
• and
• a number of inter-locale connections required to connect the plurality of nodes of the graph.
