Do you have any programming experience?

Whisper.cpp is fairly easy to use, there are plenty of open source libraries for audio input, and sending text as keystrokes in Windows is quite easy.

There may very well be an existing solution, but if you want to put something together yourself, all the major building blocks already exist. You’d just have to write the code to tie it all together.

I’m curious, why does this require OpenSSL in order to compile? I’m not aware of any audio formats that use encryption, but I could be wrong.

My first thought was for connecting to https streams, but I don’t remember Winamp having this capability. “Back in the day,” I used Winamp for playing local audio and RealPlayer for what little streaming was available.

I have the utmost respect for the ffmpeg developers; writing ASM is a skill I do not possess. I do have to wonder, though, would it be easier for cross-platform compatibility to write in C instead. I have always understood that C generally compiles almost directly to assembly with little to no abstraction overhead, and it would not require platform-specific ASM code. What is the logic in choosing ASM over C? I have no doubt there is a good reason.
