Avalonia VS PortAudio

Yes, but the portable GUI frameworks by Microsoft themselves are generally not very good, and they tend to be abandoned after a couple of years. Avalonia is developed outside of the Microsoft corporate madness and seems to be slowly becoming the defacto cross-platform framework because it is expected to last a bit longer than a manager's attention span: https://avaloniaui.net/. - Source: Hacker News / 3 months ago

You should be able to use Avalonia[1] as an alternative GUI layer on Windows, Linux, macOS, iOS and Android. There is a beautiful Avalonia.FuncUI[2] and Avalonia.FuncUI.Elmish[3] which is an implementation of Elmish[4] (based of the Elm language[4]) for F#.

To bad Microsoft refuse to work on proper cross platform WPF support. I've tried Avalonia UI[0], but it's just not the same. For instance the lack of a proper out-of-the-box virtualized list. [0] https://avaloniaui.net/. - Source: Hacker News / 6 months ago

For desktop, Avalonia, hands down. https://avaloniaui.net/ Open source, powered by Skia, backed by JetBrains, and quite battle-tested at this point for small to medium-sized apps. In theory perfectly capable for enterprise as well, since it's basically a spiritual successor to WPF, which has been an industry standard for about 15 years. They're diving into mobile and WASM well, but that's more of a recent effort... - Source: Hacker News / 7 months ago

FYI PyAudio built on this software: http://portaudio.com/ which interfaces directly with Alsa/OSS (refer to the sounds system page, I'm not saying Open-Source Software here) which PulseAudio also does. Source: about 3 years ago
