LV2 |
||||
=== |
||||
|
||||
LV2 gives programmers the ability to write audio processors (or "plugins") in |
||||
C/C++ which can be dynamically loaded into a range of applications (or |
||||
"hosts"). |
||||
|
||||
This core specification is deliberately as short and simple as possible, but is |
||||
designed so that extensions can be defined to add more advanced features. |
||||
|
||||
More information about LV2 can be found at <http://lv2plug.in>. |
||||
|
||||
|
||||
Using LV2 |
||||
--------- |
||||
|
||||
Applications that use LV2 plugins should depend on this package. It includes a |
||||
header, LV2 bundle, and a pkg-config file. To compile against LV2, build |
||||
scripts should check for the pkg-config package "lv2core", or simply check for |
||||
the header "lv2/lv2plug.in/ns/lv2core/lv2.h". |
||||
|
||||
The appropriate C include for LV2 specifications is based on their URI, e.g.: |
||||
|
||||
#include "lv2/lv2plug.in/ns/lv2core/lv2.h" |
||||
|
||||
Is how code should include the header "lv2.h" in this bundle, which defines the |
||||
specification with URI "http://lv2plug.in/ns/lv2core". Other specifications |
||||
should follow this convention, e.g. the correct way to include the header |
||||
"foo.h" in the extension "http://example.org/foo" is: |
||||
|
||||
#include "lv2/example.org/foo/foo.h" |
||||
|
||||
|
||||
Packaging |
||||
--------- |
||||
|
||||
Please package these components in a single package (i.e. do not split the |
||||
headers, data, and program into separate packages). This package, in its |
||||
entirety, is a build and run time dependency of any code that uses LV2. |
||||
Distributions are encouraged to include it with package name "lv2core". |
