A software plug-in module that interfaces to a media editing host application generates and embeds information about a media composition being edited directly within portions of the user interface generated by the host application. The information may include a custom representation of media data of a time-based element of the media composition that replaces, augments, or overlays a timeline representation of the element generated by the host application. Media editing functionality provided by the plug-in may be accessed by an operator based on viewing or interacting with the custom representation. Results of analysis of the media composition by the plug-in may be displayed within the host-generated timeline and used by an operator as a basis for performing edit operations with standard host tools or with plug-in generated tools. Plug-ins may embed their interfaces within user interfaces of host digital audio workstations, non-linear video editing systems, and music notation applications.

Embedded plug-in presentation and control of time-based media documents

An audio signal processing graph is automatically recomposed to optimize its properties by reassigning and instantiating its nodes on available locales such that the number of inter-locale connections is minimized and latency between inputs, such a performer's live input, and outputs, such as a monitored recording mix, is minimized. The recomposition exploits associative, commutative, and decomposition properties of certain node types, including mixer nodes. A graph recomposition may decompose a mixer node into a first stage instantiated by a software plug-in hosted by a computer running a digital audio workstation in a first locale, and a second stage assigned to an audio processing device in a second locale. Automatic signal graph recomposition occurs when the system is initialized, the graph is reconfigured, a new desired behavior of the graph is specified, or the available network resources are changed.
