  {
      [Command("join")]
      public async Task JoinChannel(IVoiceChannel channel = null)
      {
          // Get the audio channel
          channel = channel ?? (Context.Message.Author as IGuildUser)?.VoiceChannel;
          if (channel == null) { await Context.Message.Channel.SendMessageAsync("User must be in a voice channel, or a voice channel must be passed as an argument."); return; }
  
          // For the next step with transmitting audio, you would want to pass this Audio Client in to a service.
          var audioClient = await channel.ConnectAsync();
  
          await SendAsync(audioClient,"audio/hello.mp3");
      }
  
      private Process CreateStream(string path)
      {
          return Process.Start(new ProcessStartInfo

          using (var ffmpeg = CreateStream(path))
          using (var output = ffmpeg.StandardOutput.BaseStream)
          using (var discord = client.CreatePCMStream(AudioApplication.Mixed))
          {
              try { await output.CopyToAsync(discord); }
              finally { await discord.FlushAsync(); }
          }
