Как сделать записи с использованием C#.net, Naudio, Asio4all, Winui 3 (часть приложения Windows SDK) и Visual Studio 202 ⇐ C#

[Anonymous]

Цель состоит в том, чтобы использовать Naudio, Asio4all, Winui 3 (часть приложения Windows SDK) и C#.net в Visual Studio 2022 для ведения записей. К сожалению, такая цель еще не была достигнута. void OnAsioOutAudioAvailable(object sender, AsioAudioAvailableEventArgs e)
{
#pragma warning disable 618
var samples = e.GetAsInterleavedSamples();
#pragma warning restore 618
writer.WriteSamples(samples, 0, samples.Length);
}
< /code>
Как можно переписать этот код для ведения записей? Любая помощь будет высоко оценена. Компьютер, чтобы установить Naudio & Winui 3 в проекте, и использовать C#.net в проекте.
