		Recommendation for Loudness of Audio Streaming and Network File Playback
		Loudness Type	AES Streaming
		Integrated (I)	–16 LUFS (±0.5 LU)*
		True Peak (TPmax)	–1 dBTP
		Reference: AES Technical Document
		Please note: A −20 LUFS lower limit has been chosen as the lowest current practical value for streaming, as some current mobile devices have insufficient gain to allow the common production targets of −23 or −24 LUFS to be heard at a satisfying loudness even if the volume control is turned all the way up.
