Dplug is a library for crafting native audio plugins as simply as possible.

Current features

  • Creating VST 2.4 plugins on Windows and Mac OS X, 32-bit and 64-bit
  • Creating Audio Unit v2 plugins for Mac OS X, 32-bit and 64-bit
  • Comes with a few music DSP algorithms
  • Comes with a number of tools to make plugin creation faster (bundling, color correction, regression tests)
  • Graphics renderer inspired by PBR to keep installers small

Release notes

  • v4.x.y (in progress)
  • macOS Sierra support fixed.
  • To allow that, the D runtime is now linked with but disabled. No GC, no TLS, no global ctor/dtor.
  • does not rely on gfm:core anymore.
  • v3.x.y (9th May 2016):
  • Audio Unit compatibility added, with both Cocoa and Carbon UI. What is still missing from AU: Audio Component API, sandboxing, v3. In other words it's on parity with IPlug but not JUCE.
  • The release tool is now much more friendly to use.
  • Special keys in dub.json are now expected in a plugin.json file next to dub.json. In the future it will be the place of autority for information about a plugin, for now this has to be duplicated in buildPluginInfo() override. An empty plugin.json is OK, defaults are in place.
  • The Wiki became a place to visit.
  • no API guarantee yet. Do not expect things not to change.
  • v2.x.y: (6th January 2016)
  • this is the next release, and API will break without notice
  • supports VST for 32-bit and 64-bit, Windows and Mac
  • release tool now expects a VST or AU configuration, see the distort example for details
  • special dub.json key CFBundleIdentifier became CFBundleIdentifierPrefix, see how distort works to update your plugins dub.json
  • 10.6 compatibility dropped.
  • v1.x.y: (26th May 2015)
  • initial release, VST support for 32-bit and 64-bit, Windows and Mac

How to build plugins

For Windows:

  • Use DMD >= v2.067 or LDC >= v1.0.0-b2
  • Install DUB, the D package manager: http://code.dlang.org/download
  • Go into an example directory
  • Type dub --compiler=dmd or dub --compiler=ldc2 depending on the compiler used.

For OS X:

  • Use DMD >= v2.067 or LDC >= v1.0.0-b2
  • Install DUB, the D package manager: http://code.dlang.org/download
  • Build and use the release tool which is in the tools/release/ directory.
  • Go into an example directory
  • Type release --compiler dmd or release --compiler ldc depending on the compiler used.
  • This tool is needed to create the whole bundle.

FAQ

  • How do I build plugins for OS X?

You need to use the release program in the toolsdirectory. This tool create a bundle and Universal Binaries as needed. Like most D programs, you can build it by typing dub.

  • What is the oldest supported Windows version?

Windows Vista. Users report plugins made with both DMD and LDC work on Windows XP. But this target isn't officially supported by D compilers.

  • What is the oldest supported OS X version?

OS X 10.7+ Probably possible to go below in cases, but impractical. To try that modify the "release" tool. D compilers do not support OS X 10.6 anymore so you won't get any help in case of problem.

  • What D compiler can possibly be used?

See .travis.yml for supported compilers.

  • Is Dplug stable?

No. The interface tend to change for improvements. Pin the version you use using DUB version specifications.

  • Will you fix the bugs I encounter?

I might but don't guarantee it. This software is released for free. It doesn't mean support is for free. If you want something to be changed, you can:

  • ask it
  • do it yourself
  • use the bounty system

Comparison vs IPlug

Pros:

  • No dispatcher-wide mutex lock. All locks are of a short duration, to avoid blocking the audio thread.
  • 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, at the cost of more work.
  • No need to deal with resource compilers: D can import("filename.ext") them.
  • No need to maintain IDE project files, they are generated by DUB.
  • No need to make Info.plist files, they are generated instead.
  • No need to use Xcode whatsoever.
  • No need to use a MacOSX SDK.

Cons:

  • Less battle-tested in general.
  • API may change without notice (pin the version of dplug you use).
  • AAX and VST3 unimplemented.
  • No resizeable UI yet.
  • No HDPI support yet.
  • No modal windows, and no plans for it.

Licenses

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 heavily 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 license, don't make plugins with Dplug. Find the VST3 SDK there: http://www.steinberg.net/en/company/developers.html

Misc

Other source files fall under the Boost 1.0 license.
