Questions tagged [audiosession]

An audio session is a group of related audio streams.

An audio session contains either rendering streams or capture streams, but not both. By default, the volume and mute settings for a rendering session are persistent across system restarts. The volume and mute settings for a capture session are not persistent. A session that contains streams that operate in loopback mode is treated the same as a capture session.
