Trait discord::voice::AudioReceiver

pub trait AudioReceiver: Send {
    fn speaking_update(&mut self, ssrc: u32, user_id: &UserId, speaking: bool);
    fn voice_packet(&mut self, ssrc: u32, sequence: u16, timestamp: u32, stereo: bool, data: &[i16]);
}

A receiver for incoming audio.

Required Methods

fn speaking_update(&mut self, ssrc: u32, user_id: &UserId, speaking: bool)

Called when a user's currently-speaking state has updated.

This method is the only way to know the ssrc to user_id mapping, but is unreliable and only a hint for when users are actually speaking, due both to latency differences and that it is possible for a user to leave speaking true even when they are not sending audio.

fn voice_packet(&mut self, ssrc: u32, sequence: u16, timestamp: u32, stereo: bool, data: &[i16])

Called when a voice packet is received.

The sequence number increases by one per packet sent, and can be used to reorder packets if they have been received out of order. The timestamp increases at 48000Hz (typically by 960 per 20ms frame). If stereo is true, the length of the data slice is doubled and samples have been interleaved. The typical length of data is 960 or 1920 for a 20ms frame, but may be larger or smaller in some situations.
