Introduction to LADSPA
LADSPA is the "Linux Audio Developer's Simple Programming API," whose goal is to provide a versatile audio plug-in capability similar to VST. It is deliberately designed to be extremely simple. As described on the project web site, "The 'S' in 'LADSPA' is meant seriously." The LADSPA development "framework" consists of just one C header file, plus the development tools you will build here.
Project Homepage: http://www.ladspa.org
Common Build Instructions
The build system is not autotools based. However, the makefile is so simple that you will probably want to simply edit and run the makefile manually.
Build the package
cd src
edit makefile
INSTALL_PLUGINS_DIR = ...
INSTALL_INCLUDE_DIR = ...
INSTALL_BINARY_DIR = ...
make
Install the package
make install create multiarch wrappers for all 3 binaries
Here is a script that automates this process, while also adding DESTDIR capability, which is missing in the original makefile:
cat > build.sh << "EOF"
: ${CLFS_LIB32:="lib"}
: ${CLFS_LIBN32:="lib32"}
: ${CLFS_LIB64:="lib64"}
: ${CLFS_LIB:="lib"}
eval CLFS_LIB='$'CLFS_LIB${USE_ARCH} &&
eval BUILD='$'BUILD${USE_ARCH} &&
eval LD_BUILD='$'LD_BUILD${USE_ARCH} &&
pushd src &&
if [ -e makefile-original ]; then
make clean
mv -f -v makefile-original makefile
fi
CLFS_LIB=${CLFS_LIB} \
sed -i-original \
-e 's/$(INSTALL_PLUGINS_DIR)/$(DESTDIR)$(INSTALL_PLUGINS_DIR)/g' \
-e 's/$(INSTALL_INCLUDE_DIR)/$(DESTDIR)$(INSTALL_INCLUDE_DIR)/g' \
-e 's/$(INSTALL_BINARY_DIR)/$(DESTDIR)$(INSTALL_BINARY_DIR)/g' \
-e "s|/usr/local|/usr|g" \
-e "s|/lib/|/${CLFS_LIB}/|g" \
makefile &&
make \
DESTDIR=${DESTDIR} \
CC="gcc ${BUILD}" \
CPP="g++ ${BUILD}" \
LD="ld ${LD_BUILD}" &&
make install &&
if [ "$USE_ARCH" != "" ]; then
mv -v ${DESTDIR}/usr/bin/analyseplugin ${DESTDIR}/usr/bin/analyseplugin-${USE_ARCH} &&
mv -v ${DESTDIR}/usr/bin/applyplugin ${DESTDIR}/usr/bin/applyplugin-${USE_ARCH} &&
mv -v ${DESTDIR}/usr/bin/listplugins ${DESTDIR}/usr/bin/listplugins-${USE_ARCH}
fi
if [ "${USE_ARCH}" == "64" ]; then
ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/analyseplugin &&
ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/applyplugin &&
ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/listplugins
fi
popd
EOF
chmod +x build.sh
Non-Multilib
Compile and install the package:
./build.sh
Multilib
32Bit
Compile and install the package:
USE_ARCH=32 ./build.sh
N32
Compile and install the package:
To Do: (Please Contribute. It is intended that "USE_ARCH=N32 ./build.sh" should work.)
64Bit
Compile and install the package:
USE_ARCH=64 ./build.sh
Configuring
An environment variable, LADSPA_PATH, is required.
cat > /etc/profile.d/50-ladspa.sh << "EOF" export LADSPA_PATH=/usr/lib/ladspa:/usr/lib32/ladspa:/usr/lib64/ladspa EOF

Short Descriptions
| analyseplugin, applyplugin, listplugins | are tools for inspecting and testing ladspa plug-ins. |
|---|---|
| amp.so, delay.so, filter.so, noise.so, sine.so | are sample plug-ins |
| /usr/include/ladspa.h | is the API, in its entirety. The comments in this (well-commented) header file comprise the API documentation. |
