Package pipe allows to build and execute DSP pipelines. This package offers an opinionated perspective to DSP. It's based on the idea that the signal processing can have up to three stages: It implies the following constraints: Current implementation supports two execution modes: sync and async. In async mode every stage of every line is executed in by its own goroutine and channels are used to communicate between them. Sync mode allows to run one or more lines in the same goroutine. In this case lines and stages within lines are executed sequentially, as-provided. Pipe allows to use different modes in the same run. Each stage in the pipeline is implemented by components. For example, wav.Source reads signal from wav file and vst2.Processor processes signal with vst2 plugin. Components are instantiated with allocator functions: Allocator functions return component structures and pre-allocate all required resources and structures. It reduces number of allocations during pipeline execution and improves latency. Component structures consist of mutability, run closure and flush hook. Run closure is the function which will be called during the pipeline run. Flush hook is triggered when pipe is done or interruped by error or timeout. It enables to execute proper clean up logic. For mutability, refer to mutability package documentation. To run the pipeline, one first need to build it. It starts with a line definition: Line defines the order in which DSP components form the pipeline. Once line is defined, components can be bound together. It's done by creating a pipe: New executes all allocators provided by lines and binds components together into the pipe. Once pipe is built, it can be executed. To do that Start method should be called: Start will start and asynchronously run all DSP components until either any of the following things happen: the source is done; the context is done; an error in any of the components occured.
