// Process a welcome
session.processWelcome(welcomeBuffer);

// The current voice privacy code of the session, updated after a commit/welcome
session.voicePrivacyCode; // a 30 digit string or an empty string for not started sessions

// Encrypt/decrypt voice packets

// Encrypt packets with a specified media type and codec, use this before transport encryption
session.encrypt(MediaType.AUDIO, Codec.OPUS, packet);
// Really only opus is supported right now so just use the shorthand method
session.encryptOpus(packet);
// Decrypt a packet from a user, use this after transport decryption
