Package: normalize-audio Version: 0.7.7-11 Severity: wishlist The TV channels in Europe are standardizing on the ITU R128 loudness standard[1] based on the loudness measurement standard ITU BS.1770 standard[2]. This is related to the dBFS scale normalize-audio operate on, but it not quite the same according to a report from BBC[3].
It would be great if the normalize-audio tool supported normalizing to a specific LUFS level. There are a few packages already in Debian related to the R128 standard: ebumeter - Loudness measurement according to EBU-R128 libebur128-dev - implementation of the EBU R128 loudness standard (development files) libgrooveloudness-dev - loudness scanner sink for libgroove (development files) Perhaps the libraries can be used to add R128/BS.1770 support to normalize-audio? I'm currently working on getting bs1770gain[4] into Debian (WNPP #781026), which provide a LUFS meter and ability to normalize audio, but it would be great if normalize-audio also supported this scale. :) [1] <URL: https://tech.ebu.ch/docs/r/r128.pdf > "Loudness normalisation and permitted maximum level of audio signals" [2] <URL: http://www.itu.int/rec/R-REC-BS.1770/en > "Algorithms to measure audio programme loudness and true-peak audio level" [3] <URL: http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP202.pdf >, "Terminology for loudness and level dBTP, LU, and all that" by Andrew Mason with the BBC.
