Playback with Controls

In this example we have an audio player with the following controls:

• Start clip playback
• Stop clip playback
• Clip volume
• Clip pan
• Clip pitch
• Track mute state

using Aura;
using Aura.Clips;
using Aura.Tracks;

public class Program
{
    private const string _menu = "\n\nA: start clip playback\nS: stop clip playback\nV: change clip volume\n" +
        "P: change clip pan\nT: change clip pitch\nM: mute/unmute audio track\nEsc: exit\n";

    private static void Main()
    {
        AuraMain.Init(); // Initialize the framework

        // Create an audio device using the WASAPI API in exclusive mode
        AuraMain.CreateWasapiDevice(true);

        // Create an audio clip from an audio file
        var audioClip = new AudioClip("path/to/sound.wav");

        // Create an audio track with a name
        var audioTrack = new AudioTrack("MyTrackName");

        // Add the created audio clip to the audio track
        audioTrack.AddClip(audioClip);

        // Start the clip playback
        audioClip.Play();

        bool exit = false;
        while (!exit)
        {
            string status = $"Playing: {audioClip.Playing} | Volume: {audioClip.Volume}dB | Pan: {audioClip.Pan} " +
                    $"| Pitch: {audioClip.Pitch} | Muted: {audioTrack.Muted}";

            Console.WriteLine(status);
            Console.WriteLine(_menu);

            var option = Console.ReadKey(true);
            switch (option.Key)
            {
                case ConsoleKey.V: // Change clip volume
                    Console.WriteLine("Input a value between -90 and 6");

                case ConsoleKey.P: // Change clip pan
                    Console.WriteLine("Input a value between -50 and 50");
                    if (float.TryParse(Console.ReadLine(), out var pan))
