constexpr PlaybackModeFlags carb::audio::fPlaybackModeMuted = 0x00000080

flag to indicate the current mute state for a voice.

This is valid only when the fVoiceParamMute flag is used. When this flag is set, the voice’s output will be muted. When this flag is not set, the voice’s volume will be restored to its previous level. This is useful for temporarily silencing a voice without having to clobber its current volume level or affect its emitter attributes.
