vst3sdk VS SecondMonitor

But you don't have only Linux, you have (and probably first) OSX and/or Windows and then Linux, and you need an API that works well in that case. Being an in-process dll/so plugin, while fraught with perils gets you to avoid other issues (state, health, restart, identity, etc.)

Also sometimes you don't have a choice, but have to make a dll, for example:

https://github.com/steinbergmedia/vst3sdk or https://ae-plugins.docsforadobe.dev/ and many others. Sometimes it's the only viable choice.

(I wish most have used grpc/flatbuffers/whatever to communicate, but then every RPC call have to be checked/retried/handled, and or shared memory well handled, with (?) locks, etc. - not a trivial thing for someone who is deeply specialized in making a very good effect/renderer/etc instead of dealing with this extra complexity on top).

Yeah, you can use nordaudio which wraps PortAudio which has support for every major audio back-end. As for writing a VST you may have to find a way to wrap or interface with Steinberg's SDK. MIDI support is possible by using an RtMIDI wrapper, which I haven't linked because there are a few of them out there of varying quality and I don't know which is best because I just use ALSA directly for my purposes.

You can read the VST3 SDK manual for yourself here https://steinbergmedia.github.io/vst3\_doc/vstsdk/index.html and access the source here: https://github.com/steinbergmedia/vst3sdk.

You have to use the steinberger SDK to make a vst

But audio plugins come in many formats.

You can do VST3 as GPL. They dual license it. Lots of legalese to read but definitely an option. https://github.com/steinbergmedia/vst3sdk/issues

This is a great telemetry software for most sims, its free, itll keep logs of laps and much more. https://gitlab.com/winzarten/SecondMonitor

Probably worthwile to look into "SecondMonitor" App for ACC. https://gitlab.com/winzarten/SecondMonitor

I use a Python script to read the shared memory and generate JSON with this information, then a web page using this JSON is overlaid using OBS, and this way we transmit races on YouTube.

Here is how it looks like: https://youtu.be/ijSL8uN8cIw?t=5582

If you want to read about a public project that uses this strategy, here is the repository link:

I don't know C#, but it should work similarly. This also means you definitely don't need to use the same language to create and to consume the information.

You can try Second Monitor Software to record and analyse your car telemetry. It's free and open source, compatible with almost all simulators.

The only second monitor I knoe of is this one..

Trusting your driver feel is dangerous and you really need to try different lines to see the impact. Also download the free https://gitlab.com/winzarten/SecondMonitor to see what impact each line has on key corners (stick with Brands Hatch, it’s a good one to use to learn).

If you haven't already, take a look at Second Monitor https://gitlab.com/winzarten/SecondMonitor/-/wikis/home
