LV2 === LV2 is a plugin standard for audio systems. It defines an extensible C API for plugins, and a format for self-contained "bundle" directories that contain plugins, metadata, and other resources. See for more information. This package contains specifications (C headers and Turtle data files), documentation generation tools, tests, and example plugins. Installation ------------ See the [installation instructions](INSTALL.md) for details on how to configure, build, and install LV2 with meson. By default, on UNIX-like systems, everything is installed within the `prefix`, and LV2 bundles are installed in the "lv2" subdirectory of the `libdir`. On other systems, bundles are installed by default to the standard location for plugins on the system. The bundle installation directory can be overridden with the `lv2dir` option. The [specification bundles](lv2) are run-time dependencies of LV2 applications. Programs expect their data to be available somewhere in `LV2_PATH`. See for details on the standard installation paths. Headers ------- The `lv2/` include namespace is reserved for this LV2 distribution. Other projects may extend LV2, but must place their headers elsewhere. Headers are installed to `includedir` with paths like: #include "lv2/urid/urid.h" For backwards compatibility, if the `old_headers` option is set, then headers are also installed to the older URI-based paths: #include "lv2/lv2plug.in/ns/ext/urid/urid.h" Projects still using this style are encourated to migrate to the shorter style above.
