plugin-host - A testing host for VST development

plugin-host-cli is a CLI tool for testing VST plug-ins.

It's a simple VST host which can open a plug-in and play an audio file through it in a loop. Additionally, it supports watching the VST plug-in for changes & reloading it any time it changes.

It also supports offline rendering into a file and printing some basic diagnostics.

Usage

To run a plug-in looping over a file, on your computer's default audio output, run:

plugin-host run --plugin ./target/release/myplugin.dylib --input ./my-input-file.mp3

To host the plug-in's GUI, use the --editor flag:

plugin-host run --editor --plugin ./target/release/myplugin.dylib --input ./my-input-file.mp3

To watch the plug-in dylib for changes, use the --watch flag: (This currently won't work with an editor)

plugin-host run --watch --plugin ./target/release/myplugin.dylib --input ./my-input-file.mp3

To run off-line rendering to a file, use the --output flag:

plugin-host run --output ./output.wav --plugin ./target/release/myplugin.dylib --input ./my-input-file.mp3

Plugin Host GUI

Iced GUI

plugin-host-gui2 is a GUI for the testing host.

Features supported in the GUI:

• Loading the VST - Including the GUI, but with caveats
• Selecting audio IO options (input/output/driver)
• Selecting an input file
• Transport controls
• File watcher. The plugin and its editor will be reloaded on re-build.

Missing functionality:

• Volume metering/control (see #16)

Future things to improve

• Implement limiter
• Show some basic output visualizations for analysis
• Allow using the default input rather than just input files
• Implement offline rendering
