Hi, after some time messing around some lyrics files and some trial and error, I managed to come up with some tips on how to properly format your LRC lyrics into ELRC word-by-word lyrics files.
First I installed Chronograph which is a amazing linux-only LRC/ELRC editor that allows you to tap your keyboard to mark each word.
Then after that I edited the generated text with notepad and fine tuned some tags to allow for Backing Vocals and concurrent lines to appear like they do in Apple Music for example.
[00:07.26] <00:07.26> You <00:07.41> see <00:07.66> this <00:07.89> line?
[00:15.89]BG: <00:15.89> You <00:16.14> can <00:16.53> see <00:16.80> this <00:17.03> line
[00:19.54] <00:19.54> Now <00:19.77> see <00:20.04> another <00:20.27> one <00:20.52> this <00:20.98> time
Would output:
You can see this line?
You can see this line
Now see another one this time
It doesn’t matter if part of a BG line overlaps with other lines if the square bracket of each line is kept in the proper order
[00:07.26] > [00:15.89] > [00:19.54]
You can also set some color codes for female/male vocalists and duets
[00:00.000]M: <00:00.100>I <00:00.350>love <00:00.650>you
[00:03.000]F: <00:03.120>I <00:03.340>love <00:03.640>you <00:03.880>too
[00:06.000]D: <00:06.150>We <00:06.380>love <00:06.700>each <00:06.920>other
Outputs:
I love you
I love you too
We love each other
I’ll leave a practical example below:
[00:07.26] <00:07.26> Turn <00:07.41> the <00:07.66> lights <00:07.89> on!
[00:08.49]
[00:15.89] <00:15.89> Every <00:16.14> night <00:16.53> I <00:16.80> rush <00:17.03> to <00:17.25> my <00:17.58> bed
[00:19.54] <00:19.54> With <00:19.77> hopes <00:20.04> that <00:20.27> maybe <00:20.52> I'll <00:20.98> get <00:21.21> a <00:21.49> chance <00:21.95> to <00:22.18> see <00:22.42> you
[00:22.72] <00:22.72> When <00:23.05> I <00:23.31> close <00:23.55> my <00:23.78> eyes, <00:24.02> I'm <00:24.26> going <00:24.49> out <00:24.78> of <00:25.09> my <00:25.31> head

[00:38.37] <00:38.37> And <00:38.52> I <00:38.79> hope <00:39.06> it <00:39.29> rains, <00:40.39> you're <00:40.94> the <00:41.44> perfect <00:42.37> lullaby
