Instance Attribute Summary collapse
-
#encrypted ⇒ true, false
(also: #encrypted?)
deprecated
Deprecated.
Discord no longer supports unencrypted voice communication.
-
#secret_key ⇒ Object
writeonly
Sets the secret key used for encryption.
Instance Method Summary collapse
-
#connect(ip, port, ssrc) ⇒ Object
Initializes the UDP socket with data obtained from opcode 2.
-
#initialize ⇒ VoiceUDP
constructor
Creates a new UDP connection.
-
#receive_discovery_reply ⇒ Array(String, Integer)
Waits for a UDP discovery reply, and returns the sent data.
-
#send_audio(buf, sequence, time) ⇒ Object
Makes an audio packet from a buffer and sends it to Discord.
-
#send_discovery ⇒ Object
Sends the UDP discovery packet with the internally stored SSRC.
Constructor Details
#initialize ⇒ VoiceUDP
Creates a new UDP connection. Only creates a socket as the discovery reply may come before the data is initialized.
