NAME
bs1770gain - lundness scanner and normalizer based on ITU-R BS.1770
SYNOPSIS
bs1770gain [options] <file/dir> [<file/dir> ...]
DESCRIPTION
BS1770GAIN is a loudness scanner compliant with ITU-R BS.1770 and its
flavors EBU R128, ATSC A/85, and ReplayGain 2.0. It helps normalizing
the loudness of audio and video files to the same level.
See bs1770gain --help for experimental options.
Command line arguments can appear in any order.
OPTIONS
-h,--help
print this message and exit
-i,--integrated
calculate integrated loudness
-s,--shorterm
calculate maximum shortterm loudness
-m,--momentary
claculate maximum momentary loudness
-r,--range
calculate loudness range
-p,--samplepeak
calculate maximum sample peak
-t,--truepeak
calculate maximum true peak
-b <timestamp>,--begin <timestamp>
begin decoding at timestamp (in microseconds, format:
hh:mm:ss.mus)
-d <duration>,--duration <duration>
let decoding last duration (in microseconds, format:
hh:mm:ss.mus)
-u <method>,--use <method>
base replay gain calculation on method (with respect to the
-a/--apply and -o/--output options), methods: "integrated"
(default), "shortterm", or "momentary" experimental methods:
"momentary-mean" (same as "integrated"), "momentary-maximum"
(same as "momentary"), "shortterm-mean", or "shortterm-maximum"
(same as "shortterm")
-a apply the EBU/ATSC/RG album gain to the output (in conjunction
with the -o/--output option)
-o <folder>,--output <folder>
write RG tags or apply the EBU/ATSC/RG gain, respectively, and
output to folder -f <file>,--file <file> write analysis to file
-x,--extensions
enable following extensions/defaults:
1) rename files according to TITLE tag
2) read metadata from per-folder CSV file "folder.csv"
3) copy file "folder.jpg" from source to destination folder
4) automatically add the TRACK and DISC tags
5) calculate maximum true peak
6) convert to stereo
-l,--list
print FFmpeg format/stream information
--ebu calculate replay gain according to EBU R128 (-23.0 LUFS,
default)
--atsc calculate replay gain according to ATSC A/85 (-24.0 LUFS)
--replaygain
calculate replay gain according to ReplayGain 2.0 (-18.0 LUFS)
--track-tags
write track tags
--album-tags
write album tags
--unit <unit>
write tags with <unit>
--apply <q>
apply the EBU/ATSC/RG gain to the output (in conjunction with
the -o/--output option), q=0.0 (album gain) ... 1.0 (track
gain), default 0.0 (album gain)
--audio <index>
select audio index (corresponds to [0:<index>] in FFmpeg
listing, cf. -l/--list option)
--video <index>
select video index (corresponds to [0:<index>] in FFmpeg
listing, cf. -l/--list option)
--stereo
convert to stereo
--drc <float>
set AC3 dynamic range compression (DRC)
--extension <extension>
enable extension out of
"rename":
rename files according to TITLE tag
"csv": read metadata from per-folder CSV file "folder.csv"
"jpg": copy file "folder.jpg" from source to destination folder
"tags":
automatically add the TRACK and DISC tags
--format <format>
convert to format
--loglevel <level>
set loglevel,
level: "quiet", "panic", "fatal", "error", "warning", "info",
"verbose", "debug"
--xml print results in xml format
--time print out duration of program invocation
--norm <float>
norm loudness to float.
