VST Host with unix-way availability to processing wav (RIFF) files with VST Plugin with some preset from fxb/fxp-files.

You could skip this step if you're using different VST Hosts (i.e Wavosaur or Tone2 NanoHost) for creating presets.

VSTAudioProcessor.exe --vst-plugin "C:\Program Files\Common Files\VST2\Random-VST-Plugin.dll" --save-fxb --fxb "C:\temp\preset.fxb"
VSTAudioProcessor.exe --vst-plugin "C:\Program Files\Common Files\VST2\Random-VST-Plugin.dll" --save-fxb --fxb "C:\temp\preset.fxp" --fxb-format fxp
VSTAudioProcessor.exe --vst-plugin "C:\Program Files\Common Files\VST2\Random-VST-Plugin.dll" --save-fxb --fxb "C:\temp\preset.fxb" --fxb-as-params
VSTAudioProcessor.exe --vst-plugin "C:\Program Files\Common Files\VST2\Random-VST-Plugin.dll" --save-fxb --fxb "C:\temp\preset.fxp" --fxb-as-params --fxb-format fxp

Default saving type is opaque, because it saves all data from some big and complicated plugins like IL Minihost Modular. Use --fxb-as-params only if you plan to use your preset in any VST hosts, which don't support opaque type (i.e. Wavosaur).

VSTAudioProcessor supports all 5 different types for preset file (Param preset, opaque preset, opaque bank, param bank + param preset, param bank + opaque preset). You could do preset in any VST Host you usually use and then load it here.

VSTAudioProcessor.exe --vst-plugin "C:\Program Files\Common Files\VST2\Random-VST-Plugin.dll" --fxb "C:\temp\preset.fxp" --input "C:\temp\input.wav" --output "C:\temp\fxb\output.wav"

If your preset contain different Plugin Version from your current VST Plugin, use --ignore-plugin-version.

VSTAudioProcessor.exe --vst-plugin "C:\Program Files\Common Files\VST2\Random-VST-Plugin.dll" --fxb "C:\temp\preset.fxp" --input "C:\temp\input.wav" --output "C:\temp\fxb\output.wav" --ignore-plugin-version

If you need to work other media types besides RIFF you could use ffmpeg (https://www.ffmpeg.org/download.html#build-windows).

For example:

ffmpeg -i some-media-file.raw -sn -vn -c:a pcm_s16le temporary.wav
VSTAudioProcessor.exe ... --input temporary.wav --output temporary.out.wav
ffmpeg -i temporary.out.wav -c:a aac -q:a 5 output.aac

Split this package to separate VST Host and FXB/FXP file processor, and then publish it as .Net Core Nuget package.

This application WILL NEVER support any other media type except RIFF files, because of their simple not complicated nature.
