Really wanted to develop an app for #macOS that allowed changing volume per app. Exactly like how the volume mixer works on Windows. That’s the only feature I miss from Windows. It was really convenient. It is technically possible to develop an app with such functionality for macOS (and a few do exist but none are perfect from my testing), but there are many hurdles to overcome. Such as, how are you going to “record” the audio from each app? You can record system audio, but you must be able to distinguish between each app, because otherwise, how do you know which app is playing the audio? I tried to build a project like this, but it was just too difficult. Especially considering I don’t have many years of experience in software development.
