Dplug is a library for creating audio plug-ins as simply as possible. Come talk with us! if you want to learn more.
- Creating VST 2.4 plug-ins for Windows, macOS, and Linux, for 32-bit and 64-bit
- Creating Audio Unit v2 plug-ins for Mac OS X, 32-bit and 64-bit
- Creating AAX Native plug-ins for Windows and Mac OS X, 32-bit and 64-bit
- Comes with basic music DSP algorithms
- Comes with a number of
toolsto make plug-in authoring faster (bundling, color correction, regression tests, performance tests)
- Dplug is using (optional) rendering to keep installers small
- See the list of supported hosts...
Products made with Dplug
- Entropy by Cut Through Recordings
- Graillon by Auburn Sounds
- M4 Multiband Compressor by Cut Through Recordings
- Panagement by Auburn Sounds
Keep up with major changes here: Release Notes
Does Dplug support the creation of synthesizer plug-ins?
Yes. See simple-mono-synth example.
Am I forced to use the PBR graphics system?
No. There are people making plug-ins with Dplug without using PBR. How it works is that the physical channel is just filled with 0. Doing that requires a set of custom widgets, which you can find in
How do I build plugins for OS X?
You need to use the
dplug-build program in the
This tool creates Mac bundles and Universal Binaries as needed.
Like most D programs, you can build it by typing
What is the oldest supported Windows version?
Windows Vista. Users report plug-ins made with both DMD and LDC work on Windows XP. But XP isn't officially supported by D compilers.
What is the oldest supported OS X version?
OS X 10.8+.
What D compiler can possibly be used?
.travis.yml for supported compilers. The latest DMD or LDC should do.
What D compilers are recommended?
For both macOS and Windows it is recommended that you use LDC 1.2 or later.
Is Dplug stable?
Starting with v5 we'll have issue major or minor version tag for breaking changes.
If you don't want breaking change, you can pin Dplug to a specific version in your
Breaking commits are marked with BREAKING in the commit backlog.
They are always discussed on Discord before-hand.
Will you add feature X?
You have to understand that Dplug is a part-time operation, from people who spend much more time working on and releasing plug-ins.
Dplug is there to support existing products and building companies around them, not to be beta software. Being stable and bug-free is much more important to us than implementing every possible feature.
If you have money to sponsor some sanctionned feature it can definately help though.
Where do I start?
Be sure to read the Wiki in depth.
Comparison vs IPlug
- No dispatcher-wide mutex lock. All locks are of a short duration, to avoid blocking the audio thread.
- Buffer splitting: ensure your plugin never receive a buffer larger than N samples, and the corresponding MIDI input. This helps with memory consumption for the largest buffer sizes.
- Plugin parameters implement the Observer pattern.
- Float parameters can have user-defined mapping.
- PBR-style rendering lets you have a good visual quality with less disk space.
- No need to deal with resource compilers: D can
- No need to maintain IDE project files, they are generated by DUB.
dub generate visualdor
dub generate sublimetext
- No need to make Info.plist files, they are generated by
- No need to use Xcode whatsoever.
- No need to use a macOS SDK.
- Easy to install: DUB will download the library itself when building, a <= 3mb archive.
- 10x less lines of code than the next larger alternative.
- VST3 not yet implemented
- No resizeable UI
- No HDPI support
- No modal windows
Dplug has three different licenses depending on the part you need. For an audio plugin, you would typically need all three. I recommend that you check individual source files for license information.
Plugin format wrapping
Plugin wrapping is inspired by the WDL library (best represented here: https://github.com/olilarkin/wdl-ol).
Some files falls under the Cockos WDL license.
Important contributors to WDL include:
- Cockos: http://www.cockos.com/
- Oliver Larkin: http://www.olilarkin.co.uk/
However Dplug is far from a translation of WDL (see FAQ).
VST SDK translation
This sub-package falls under the Steinberg VST license.
VST is a trademark of Steinberg Media Technologies GmbH. Please register the SDK via the 3rd party developper license on Steinberg site.
Before you make VST plugins with Dplug, you need to read and agree with the license for the VST3 SDK by Steinberg. If you don't agree with the VST SDK license, don't make plugins with Dplug. Find the VST3 SDK there: http://www.steinberg.net/en/company/developers.html
Other source files fall under the Boost 1.0 license.
