Simple Voice Echo Client

Preface

Voice now almost works. To test, you can do a simple voice Echo Client one on one with your bot.

Connecting to a Voice Channel

It's necessary to first connect to a voice channel in Discord. In the test program, I do the following.

string[] split = e.message.content.Split(new char[] { ' ' }, 2);
if(split.Length > 1)
{
    DiscordChannel voiceToJoin = e.Channel.parent.channels.Find(x => x.name.ToLower() == split[1].ToLower() && x.type == "voice");
    if (voiceToJoin != null)
        client.ConnectToVoiceChannel(voiceToJoin);
}

The following snippet will is triggered inside of the client.OnMessageReceived event and finds a DiscordChannel based on the given name as an argument.

What now?

After client.ConnectToVoiceChannel is run, your bot should be connected to voice. There is a new event called AudioPacketReceived that is triggered well, whenever an audio packet is received. The DiscordAudioPacketEventArgs class houses 3 objects.

• DiscordAudioPacket
• DiscordChannel
• DiscordMember

All we really care about for right now is the DiscordAudioPacket. From here, echoing is super easy. client.EchoPacket wraps the voice client's internal packet echoing function and you just need to call that and pass the EventArgs's audio packet. Voila! Your bot should echo your voice back at you!
