getAudioLevelMetaLevel :: MonadIO m => AudioLevelMeta -> m Word8 Source #
Get the value of the “level” field.
When overloading is enabled, this is equivalent to
get audioLevelMeta #level
setAudioLevelMetaLevel :: MonadIO m => AudioLevelMeta -> Word8 -> m () Source #
Set the value of the “level” field.
When overloading is enabled, this is equivalent to
setaudioLevelMeta [ #level:=value ]
meta
parent Meta
getAudioLevelMetaMeta :: MonadIO m => AudioLevelMeta -> m Meta Source #
Get the value of the “meta” field.
When overloading is enabled, this is equivalent to
get audioLevelMeta #meta
voiceActivity
whether the buffer contains voice activity
getAudioLevelMetaVoiceActivity :: MonadIO m => AudioLevelMeta -> m Bool Source #
Get the value of the “voice_activity” field.
When overloading is enabled, this is equivalent to
get audioLevelMeta #voiceActivity
setAudioLevelMetaVoiceActivity :: MonadIO m => AudioLevelMeta -> Bool -> m () Source #
Set the value of the “voice_activity” field.
When overloading is enabled, this is equivalent to
setaudioLevelMeta [ #voiceActivity:=value ]
