Some channels are very load, others are less loud, and -ads tend to shout very high to get the attention of the viewers, and -the viewers do not like this. This fact is well known to the TV -channels. See for example the BBC white paper -"<a href="http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP202.pdf">Terminology -for loudness and level dBTP, LU, and all that</a>" from 2011 for a -summary of the problem domain. To better address the need for even -loadness, the TV channels got together several years ago to agree on a -new way to measure loudness in digital files as one step in -standardizing loudness. From this came the ITU-R standard BS.1770, -"<a href="http://www.itu.int/rec/R-REC-BS.1770/en">Algorithms to -measure audio programme loudness and true-peak audio level</a>".</p> - -<p>The ITU-R BS.1770 specification describe an algorithm to measure -loadness in LUFS (Loudness Units, referenced to Full Scale). But -having a way to measure is not enough. To get the same loudness -across TV channels, one also need to decide which value to standardize -on. For European TV channels, this was done in the EBU Recommondaton -R128, "<a href="https://tech.ebu.ch/docs/r/r128.pdf">Loudness -normalisation and permitted maximum level of audio signals</a>", which -specifies a recommended level of -23 LUFS. In Norway, I have been -told that NRK, TV2, MTG and SBS have decided among themselves to -follow the R128 recommondation for playout from 2016-03-01.</p> - -<p>There are free software available to measure and adjust the loudness -level using the LUFS. In Debian, I am aware of a library named -<a href="https://tracker.debian.org/pkg/libebur128">libebur128</a> -able to measure the loudness and since yesterday morning a new binary -named <a href="http://bs1770gain.sourceforge.net">bs1770gain</a> -capable of both measuring and adjusting was uploaded and is waiting -for NEW processing. I plan to maintain the latter in Debian under the -<a href="https://qa.debian.org/developer.php?email=pkg-multimedia-maintainers%40lists.alioth.debian.org">Debian -multimedia</a> umbrella.</p> - -<p>The free software based TV channel I am involved in, -<a href="http://www.frikanalen.no/">Frikanalen</a>, plan to follow the -R128 recommondation ourself as soon as we can adjust the software to -do so, and the bs1770gain tool seem like a good fit for that part of -the puzzle to measure loudness on new video uploaded to Frikanalen. -Personally, I plan to use bs1770gain to adjust the loudness of videos -I upload to Frikanalen on behalf of <a href="http://www.nuug.no/">the -NUUG member organisation</a>. The program seem to be able to measure -the LUFS value of any media file handled by ffmpeg, but I've only -successfully adjusted the LUFS value of WAV files. I suspect it -should be able to adjust it for all the formats handled by ffmpeg.</p> - - -
