Important:
Audio level and loudness level are two
different measurements! Even if we are
using the same digital level scale!
Recommendation:
Let’s talk about loudness in LUFS or LU
(Loudness Units), in difference to audio
level in dBFS.
It’s all defined in ITU standard!
ATSC (RP A/85) Northern America
C.A.L.M. Act is the law in USA
Target Level: -24 LKFS
EBU (R128) Europe
AGCOM Italy, PNBC Poland
Target Level: -23 LUFS
ARIB (TR-B32) Japan
ITU 1770, 1771, 1864
Target Level: -23 LUFS
ABERT, ABRA, ARIB Brazil
Considering standards like
ITU BS.1770-2
ABA (OP-59) Australia
No specific Target Level;
"excessively noisy or strident
material" prohibited
A number of professional references are
given (globally or for certain regions):
TV broadcast -23/-24 LUFS
Music streaming -16 LUFS
OTT/streaming -24…-16 LUFS
Radio podcast -18…16 LUFS
YouTube max -13 LUFS
… Apple max -16 LUFS
Why shouldn’t audio (sources and
destinations) in the car being referenced to
the common (ITU based) loudness
standards and references?
-23/-24 LUFS?

Challenges for car audio
Always optimum loudness and sound
Optimized reproduction for low dynamic and low quality content
No need for manual volume control
Optimized speech intelligibility
Best perception for speech based information
also for mixes with different loudness of audio bed (voice over)

Challenges for car audio
Optimized audio feeling
Dynamic audio control for best performance in every car model
Customized adaptation
Smart audio processing configured in user profiles
(by using adaptive and autonomous audio processing algorithms
as well as intelligent and self-learning procedures).
