That's a different issue, namely "gating vs. no gating". What I meant was comparing "-8 LU gating vs. -10 LU gating (and maybe vs. -9 LU gating)".
For the "Authentic programme 2, stereo, wide Loudness Range (WLR) programme segment; similar in genre to a movie/drama" there is a huge difference of about 4.5 LU.
Hey, is this thing lossless if I use it on mp3 files?
However R128gain presents this as being -1.4 LU which I would interpret as 1.4 LU below the reference. I would equal -1.4 LU with -24.4 LUFS. Why does R128gain present the numbers in this way?
That's how replaygain was defined several years ago: http://replaygain.hydrogenaudio.org/calibration.html
Sorry for the dumb question, but even after googling I'm still at a loss... What does this tool do?Is it like mp3gain with different mathematics?
@pbelkner, I appreciate your posting of the lib1770 code, and have a question about the gating constants. From my reading of bs1770_stats.c, the gating overlap is set to 50% of the of the 400 ms window. However, BS.1770-2 (03/2011) specifies a gating overlap of 75%. Shouldn't the overlap be 300 msec instead of 200 msec?
I have been testing the latest version (0.8.1). After scanning a number of mp3 files I noticed the track duration of the generated files were wrong.When the r128 scanner writes the mp3 files, vbr mp3 get written as cbr mp3. They play alright but the track duration is totally messed up.Mp3 were encode with lame 3.98.4 (-v2).Used ffmpeg-r26397-swscale-r32676-mingw32-shared.R128Gain 0.8.1 setting algorithm to BS 1770 and compatible Replaygain.Could this time issue be fixed?Greetings,Ben
a. can i make the tool to work without tags, like wav in -> modified wav out?
b. can i say to the tool to do a file by file (now by default, if it crashes in between, the entire sample-set is not written)(cmd used was: r128gain --r128 --r128-compatible --gate=-10.0 --true-peak=on --regression e:\!tmp -o e:\!tmp2)
r128gain --gate=-10.0 e:\!tmp > out.txt
r128gain --progress=off --gate=-10.0 e:\!tmp > out.txt
A-weighting is known to overestimate the loudness of high frequencies, esp. > 4kHz.
