Subject: [xmms-devel] Exact time based music player w/ custom fading
(tricky!!)

Hi!
I'm trying to find a music player that is capable of playing music at exact
(read: absolute) times w/ different fade-ins and fade-outs. The playlists
contain absolute time (i.e. 07:03:42) at which the then given mp3
(056-001.mp3) starts playing. There is extra fade-in and fade-out info in
the playlist: fadein-startpoint (there is songs which do not start at
00:00:00), fadein-duration in seconds, dbA-value from which the fadein
starts (it's not the usual 0-to-100 fade!), mixpoint (i.e. the time at which
the following song starts to crossfade-in), fadeout-startpoint, fadeout
duration, fadeout-to-dBA value. An A (or any other character we can chosse)
tells the system that the following song must start exactly at the given
time, every following track has to follow the fadein-mixpoint-fadeout
schedule and not necessarily the time given.
Confusing enough? ;-)
Here's an example (I've made this up - dont count seconds here please):
06:55:53 5052.mp3 338.664 7.368 0.047 -48 1.825 334.986 -8 1.248
A
07:00:00 17937.mp3 (...)
06:55:53 is the time at which the file should start.
5052.mp3 is the filename of the title (could be mp3 od mpg for layer II
files). 338.664 is the absolute lenght of the file w/out any cuts.
7.368 is where the title starts playing - the stuff before is left unplayed.
The title will fade in for 0.047 seconds from -48 dbA to 0 dBA.
1.825 is (in seconds from the end) where the next track starts ("Mixpoint").
The title will stop playing at 334.986 seconds,
it fades out 1.248 seconds from 0 to -8 dBA.
A again means that whatever is still playing stops at about 06:59:57 (steep
fadeout) and 17937.mp3 will start at exactly 0700h.
Lets hear it if someone thinks something like this is possible using XMMS...
Thanks for any help, directions, links etc.,
Christian.
