Audio and media

Audio-related functionality has two parts: gateway audio events, and media upload for group/C2C messages.

Audio Events

With the corresponding intents enabled, the platform sends audio state and voice/live channel member changes through the gateway:

• audio_start
• audio_finish
• on_mic
• off_mic
• audio_or_live_channel_member_enter
• audio_or_live_channel_member_exit

Audio carries channel id, guild id, audio URL, text description, and internal event id. PublicAudio represents voice/live channel member enter and exit events, with PublicAudioType distinguishing voice from live.

These events are useful for logging, metrics, state sync, or triggering normal message replies.

Media Upload for Group and C2C

Group and C2C messages can upload media first, then send a message that references the returned media.

let media = session.post_file(1, image_url, None).await?;
session.send_media_message(media).await?;

file_type follows platform values: commonly 1 image, 2 video, 3 audio, 4 file. C2C uses post_c2c_file with the same parameter shape.

When srv_send_msg is Some(true), the platform sends the uploaded file directly. When it is None or Some(false), pass the returned Media to send_media_message or GroupMessageParams::new_media / C2CMessageParams::new_media.
