R128GAIN is an FFmpeg and SoX-based EBU R128 compliant loudness scanner for audio and video files. It helps you normalize the loudness of your audio and video files to the same level.

According to FFmpeg.org, FFmpeg development has gone into overdrive. As a consequence, R128GAIN wasn't compiling any longer using the latest FFmpeg versions. This release ports R128GAIN to the latest FFmpeg API. It adds a command line and GUI option to allow choosing between the EBU R128-2 (current, dating from 2011) and EBU R128-1 (former, dating from 2010) standards. The release requires "libavformat.so.54" and "libavcodec.so.54" ("avformat-54.dll" and "avcodec-54.dll" on win32), and is again in line with the latest FFmpeg builds.
This release fixes a bug in 0.9.4 where only either the loudness or the loudness range could be computed but not both together. The result was that in almost all practical cases the loudness defaulted to -23.0 LUFS.
此版本实现 EBU R128 响度范围算法 (上帝军)。它提供了四个各自的环境变量的命令选项: $TR-轨道响度范围 ;$TRDB-在 dB/陆 ; 轨道响度范围$AR-专辑响度范围 ;和 $ARDB-dB/陆中的专辑响度范围。LIB1770 的 API (执行的响度范围算法) 有些轻微的改变,以便提供块 (400 ms 或 3000 ms。) 的长度
This release implements the EBU R128 loudness range algorithm (LRA). It provides four respective environment variables for the command option: $TR - the track loudness range; $TRDB - the track loudness range in dB/LU; $AR - the album loudness range; and $ARDB - the album loudness range in dB/LU. The API of LIB1770 (implementing the loudness range algorithm) has slightly changed in order to allow for providing the length of a block (either 400 ms or 3000 ms.)
This release provides four more environment variables for the command option: $TL - the track loudness relative to full scale; $TLDB - the track loudness relative to full scale in dB/LUFS; $AL - the album loudness relative to full scale; and $ALDB - the album loudness relative to full scale in dB/LUFS.
