NOTE

Starting in version 1.251, metering_mode in the dolby_audio_encoder task only supports a value of 1770-4.  

Starting in version 1.251, the loudness filter in the dolby_audio_encoder task has been removed for DD+, DD+JOC, and music_mode targets. It will be removed for AC4 IMS targets in version 1.252. It has been replaced with loudness_measurement for DD+, AC4 IMS, and DD+JOC; loudness_correction is also available for DD+ targets.
