ÆLAPSE
ÆLAPSE is a delay and reverb plugin. The delay is based on tape-delay mechanisms, while the reverb is inspired by (but not limited to) spring reverbs.
It is designed for a variety of applications, from subtle spring-reverb guitar tones to dreamy synth pads, as well as dub-style snare sounds.
Downloads
The plugin is available in VST, AU and LV2 format on the release page
Building
To build ÆLAPSE, you need CMake:
# Clone the repository and update submodules
$ git clone https://github.com/smiarx/aelapse.git
$ cd aelapse
$ git submodule update --init --recursive
# build
$ cmake -Bbuild -DCMAKE_BUILD_TYPE=Release .
$ cmake --build build --config Release --parallel 4
VST will be located in build/Aelapse_artifacts/Release.
On x86, you can enable the DSP_X86_DISPATCH option. This will compile the
audio section of the plugin for different architectures and select the
available one at runtime.
# build
$ cmake -Bbuild -DDSP_X86_DISPATCH=1 -DCMAKE_BUILD_TYPE=Release .
$ cmake --build build --config Release --parallel 4
You can also build with -march=native to build specifically for you machine.
$ cmake -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-march=native" .
$ cmake --build build --config Release --parallel 4
