/**
* @brief Store audio conversations to a single file.
*
* Unlike TeamTalk.SetUserMediaStorageDir(), which stores users' audio
* streams in separate files, TeamTalk.StartRecordingMuxedAudioFile()
* muxes the audio streams into a single file.
*
* The audio streams, which should be muxed together, are
* required to use the same audio codec. In most cases this is
* the audio codec of the channel where the user is currently
* participating (i.e. @c audiocodec member of #BearWare.Channel).
*
* If the user changes to a channel which uses a different audio
* codec then the recording will continue but simply be silent
* until the user again joins a channel with the same audio codec
* as was used for initializing muxed audio recording.
*
* Calling TeamTalk.StartRecordingMuxedAudioFile() will enable the
* #ClientFlag ::CLIENT_MUX_AUDIOFILE flag from TeamTalk.GetFlags().
*
* Call TeamTalk.StopRecordingMuxedAudioFile() to stop recording. Note
* that only one muxed audio recording can be active at the same
* time.
*
* @param lpAudioCodec The audio codec which should be used as
* reference for muxing users' audio streams. In most situations
* this is the #BearWare.AudioCodec of the current channel, i.e.
* TeamTalk.GetMyChannelID().
* @param szAudioFileName The file to store audio to, e.g.
* C:\\MyFiles\\Conf.mp3.
* @param uAFF The audio format which should be used in the recorded
* file. The muxer will convert to this format.
*
* @see SetUserMediaStorageDir()
* @see StopRecordingMuxedAudioFile() */
