Smart Audio for Automotive - Adaptive Multichannel Loudness Control in Car Environment

ATSC A/85

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).
