Analizator glasnosti in normalizator

S tem orodjem lahko preverite, ali vaša mešanica zvoka ustreza določenemu standardu. Orodje iz naložene datoteke ustvari poročilo o glasnosti. Prav tako lahko normalizira zvočno datoteko in jo uskladi z izbranim standardom.

Standardi glasnosti

LUFS (Loudness Units relative to Full Scale) se uporablja za merjenje glasnosti zvočne vsebine. Za različne formate prenosa obstaja širok razpon standardov in vrednosti. Spodnja preglednica vsebuje pregled.

Platform LUFS (Integrated Loudness) True Peak (dBTP) Loudness Range (LRA)
Streaming (e.g., Spotify)-14 LUFS-1 dBTP7-10 LU
YouTube & Vimeo-14 LUFS-1 dBTP6-8 LU
TV Broadcast (US, ATSC A/85)-24 LUFS-2 dBTP4-7 LU
TV Broadcast (EU, EBU R 128)-23 LUFS-1 dBTP5-10 LU
TV Advertising-24 to -20 LUFS-2 dBTP4-7 LU

TV Broadcast

U.S. TV follows the ATSC A/85 standard and targets -24 LUFS, while Europe follows EBU R 128 and targets -23 LUFS, both with a true peak of -1 to -2 dBTP to prevent distortion and ensure broadcast quality.

Cinema

Cinema audio typically has a much wider dynamic range, allowing for very quiet moments and very loud moments. Still, true peak levels should not exceed -3 dBTP to -6 dBTP.

YouTube and Video

Similar to streaming platforms, these platforms also aim for -14 LUFS for consistency and to avoid drastic changes in volume from one video to the next.

Streaming

To ensure consistency across content types, streaming platforms such as Spotify have standardized on -14 LUFS.

TV Commercials

TV commercials are typically louder than regular TV content to attract attention, often falling between -24 and -20 LUFS.

VOD

Video-on-demand services closely follow broadcast TV standards, typically around -24 LUFS with a similar true peak.

Podcasts

Podcasts are targeted at -16 LUFS for clear and consistent playback across devices. This is similar to mobile content.

DVD/Blu-ray

Physical media such as DVDs and Blu-rays target -27 LUFS to maintain high dynamic range and theater-like audio quality.

Radio

Radio broadcasts typically aim for -16 LUFS to ensure clear audio in various listening environments and signal strengths.

Tolerance Levels

Ravni tolerance

V Evropi je v standardu EBU R128 dovoljeno odstopanje ±1 LU, kar pomeni, da je sprejemljivo odstopanje do 1 LUFS nad ali pod ciljno vrednostjo. V ZDA je v skladu z ATSC A/85 dovoljeno odstopanje ±2 LUFS. Za kinematografsko produkcijo ni fiksne ciljne vrednosti LUFS, vendar je tipična glasnost lahko med -27 in -24 LUFS. Spotify želi doseči glasnost -14 LUFS brez izrecne tolerance, vendar se vsebina, ki znatno odstopa, običajno samodejno prilagodi. Tudi YouTube si prizadeva za glasnost -14 LUFS, vsebina, ki presega to vrednost, pa se samodejno prilagodi.

Konkretna toleranca je lahko odvisna od politik storitve ali platforme, vendar je treba na splošno upoštevati ciljne vrednosti, da se zagotovita najboljša kakovost in skladnost zvoka.
