Overview

+

There are a large number of open source and free software synthesis packages in use or development at this time. This API ("LV2") attempts to give programmers the ability to write simple "plugin" audio processors in C/C++ and link them dynamically ("plug" them) into a range of these packages ("hosts"). It should be possible for any host and any plugin to communicate completely through this interface. - +

This API is deliberately as short and simple as possible. The information required to use a plugin is in a companion data (RDF) file. The shared library portion of the API does not contain enough information to make use of the plugin possible; the data file is mandatory. - +

Plugins can operate on any type of data. Plugins have "ports" that are inputs or outputs and each plugin is "run" for a "block" corresponding to a short time interval measured in samples. The plugin may assume that all its input and output ports have been connected to the relevant data location (using the connect_port() function) before it is asked to run, unless the port has been set "connection optional" in the plugin's data file. - +

This "core" specification defines two types of port data, equivalent to those in LADSPA: control rate and audio rate. Audio rate data is communicated using arrays with one float element per sample processed, allowing @@ -112,20 +114,22 @@ rate data is communicated using single float values. Control rate data has a single value at the start of a call to the run() function which is considered valid for the duration of the call to run(). Thus the "control rate" is determined by the block size, controlled by the host. - +

Plugins reside in shared object files suitable for dynamic linking (e.g. by -dlopen() and family). This file provides one or many plugins via the +dlopen() and family). This object provides one or more plugin descriptors via the lv2_descriptor() function. These plugins can be instantiated to create "plugin instances", which can be connected together to perform tasks. - +

This API contains very limited error-handling. - -

Threading Rules
