You can use Vim to control VLC and edit song lyrics or audio transcripts:
- You can add audio timing information to each line of text transcript.
- You can cue VLC audio to the time/line you are editing.
You will need:
- Vim to edit text.
- Perl to connect gvim to vlc via a socket.
- VLC.
Below: Modify the path to Perl and Vim script according to the directory you save them in.
Setup vlc to listen on a socket
" VLC setup: $ vlc > tools > prefs > main interface > enable RC, " Tcp-Input=[localhost:2150] .. ~/vim/vlc.pl will open this socket. " Console: [donot_open] console
Vim setup
" VIM Setup:
" c:\> vim c:/atmp/happy.lrc
" :so %
" and cline is '[0:23.10] file:///C:/atmp/happy.mp3' .. press F9 to play from 23s
" Music player key:
" [F2] Play
" [F3] Stop
" [F4] Pause toggle
" Lyric editor keys:
" [F9] Set filename/time from cline to vlc, or get filename/time to cline.
" [F10] Get file from vlc into cline.
" [F11] Get Time from vlc into cline.
" Notes:
" To debug: change 'perl ~/vim/vlc.pl' to 'vimrun perl ~/vim/vlc.pl -debug'
" Testing:
" Tested gvim73,cygwin perl 5, cygwin,vlc 2, on XP-PRO SP4.
" 1. file:///c:/atmp/happy.mp3 .. press F9 play this file in vlc.
" 2. [0:1:4] file:///c:/atmp/happy.mp3 .. press F9 play this file from 64 seconds.
" 3. 0:1:5 .. press F9 to cue/seek vlc to 65 second.
" 4. press F9, to add [time][filename playing in vlc] to this line.
" TODO:
" o Test Audio filenames with spaces, unicode characters
" o Test on Linux

Comments
That's a lot of script for a tip. I have done some quick formatting, but have not thought about the proposed tip yet. One point is that the "Mosh" function names are a bit jarring and should be replaced with s:. JohnBeckett (talk) 05:16, August 24, 2013 (UTC)
