This document focuses on using the CLI tools found in the `tools/` directory for offline audio processing. ## 🛠 Prerequisites * **Compiler:** LDC 1.41+ (includes DUB). * **Download:** [LDC Releases](https://github.com/ldc-developers/ldc/releases/) * **Repository:** * HTTPS: `https://github.com/AuburnSounds/Dplug.git` * SSH: `git@github.com:AuburnSounds/Dplug.git` ## 🏗 Installation & Building Tools To build any tool, navigate to its directory and run `dub`: ```bash cd Dplug/tools/ dub build -b release ``` ## 🛠 Tools | Tool | Use | |------|-----| | **process** | Process a mono or stereo.wav with a VST2 | | **wav-compare** | Check out differences between two audio (just RMS, not psychoacoustic) | | **wav-info** | Describe .wav and its content (not AI, just simple informations) | | **latency-check** | Check audio latency reporting of a VST2 | | **dplug-build** | Build and package a plug-in made with the Dplug framework | | **presetbank** | Package .fxp presets into a .fxb bank for inclusion in a Dplug plugin | Build any of the tool with: ```bash cd Dplug/tools/ dub # like for any D program dub -- --help # all the tools have an --help argument ``` ## Dplug documentation links - https://github.com/AuburnSounds/Dplug/wiki/Getting-Started - https://dplug.org/ - https://github.com/AuburnSounds/Dplug/wiki # Using Dplug `process` tool to process audio files with an effect ## Some ideas of how to use a VST2 to process audio files You can process only one .wav in, one .wav out. To use `process` you need a VST2 (get the VST2 inside the ZIP, after running the installer, x86-only) - Do pitch correction (auto-pitch) a .wav with the free Graillon 3, basic compression, gate, bitcrusher, formant-shifting https://www.auburnsounds.com/products/Graillon.html - Put a sound in binaural 3D with Panagement, change volume... https://www.auburnsounds.com/products/Panagement.html - **Increase distance** `./process -i input.wav -o output.wav -param 0 0.4` - **Reduce distance** `./process -i input.wav -o output.wav -param 0 0.1` - **Gain change +6dB volume** `./process -i input.wav -o output.wav -param 14 0.5` - **Gain change -6dB volume** `./process -i input.wav -o output.wav -param 14 0.2` - **Unchanged volume** `./process -i input.wav -o output.wav -param 14 0.354813` - **Create 10sec silent wavefile** `./process -o output.wav -param 14 0.0` - Dynamics control with Couture https://www.auburnsounds.com/products/Couture.html - Multiband compression and equalization with Lens https://www.auburnsounds.com/products/Lens.html - **Clean up recordings** with Renegate https://www.auburnsounds.com/products/Renegate.html - Add **reverb** to sound files with Selene https://www.auburnsounds.com/products/Selene.html - **Change pitch** with highest quality with Inner Pitch https://www.auburnsounds.com/products/InnerPitch.html - If you need anything else not listed, please contact contact@auburnsounds.com ## How to list plug-in parameters? `process -show-params ` ## Process cmdline `process --help` Usage: process [-i input.wav] [-o output.wav] [-precise] [-preroll] [-t times] [-h] [-buffer ] [-preset ] [-param ] [-output-xml ] plugin.dll Params: -i Specify an input file (default: process silence) -o Specify an output file (default: do not output a file) -t Process the input multiple times (default: 1) -h, --help Display this help -precise Use experimental time, more precise measurement BUT much less accuracy (Windows-only) -preroll Process one second of silence before measurement -buffer Process audio by given chunk pattern (Default: 256) This is a small language: * : all remaining samples 64 : process by 64 samples 64, 512 : process by 64 samples, then only by 512 samples 1,1024,loop : process 1 samples, then 1024, then loop that pattern. Helpful to find buffer bugs in your plugin. Pattern applied separately in preroll. -preset Choose preset to process audio with -param Set parameter value after loading preset -show-params Set parameter value after loading preset -output-xml Write measurements into an xml file instead of stdout -vverbose Be verbose even if -output-xml was specified **Use -show-params and -param to setup the plugin, or use a preset (right now there is no way to list preset names or presets values)**
