System and methods are directed to operations associated with an approximate nearest neighbor search engine. More specifically, a vector semantically representing content to be added to a search index may be received. The search index may include a neighborhood graph having a plurality of nodes, where each node of the plurality of nodes is associated with content in a content repository. A plurality of nodes within the search index determined to be most semantically similar to the received vector semantically representing content to be added to the search index may be identified. The node corresponding to the received vector semantically representing content to be added to the search index to the search index may be added to the search index and a listing of nearest neighbors associated with each of the of the plurality of nodes may be updated to include an identifier associated with the added node.

An audio processing plug-in shim operates in conjunction with a plug-in host application executing on a computing device. The plug-in shim receives a stream of digital audio from the plug-in host application and transmits the digital audio to a network service executing in a network accessible remote distributed computing environment. The network service receives the digital audio and routes the digital audio to one or more audio processing plug-ins, also executing in the distributed computing environment. The audio plug-ins process the digital audio, such as by applying digital signal processing techniques to the digital audio, and return processed audio to the network service. The network service returns the processed audio to the plug-in shim executing on the remote computing device. The plug-in shim, in turn, receives the processed audio from the network service and provides the processed audio to the plug-in host application.
