LightJockey Help
via the hardware setup dialog; on the Digital Audio/Audio CD tab, select Winamp. To automatically
launch Winamp when needed, LightJockey must know the exact path to the Winamp executable
(usually winamp.exe). click to open up a file dialog and locate winamp.exe. Alternatively,
Winamp should be started manually before any attempt to use Winamp from the cue list.
Using Winamp in the cue list
When using Winamp to playback audio in the cue list, the actual digital audio file name is transferred
from the cue list to Winamp. When selecting the audio file for the cue list, switch the file type in the
file selection dialog to enable to selection of different audio file formats (Winamp actually supports
more formats than indicated in the filter - check documentation for Winamp for the exact formats
supported).

NOTES
The interface between LightJockey and Winamp has been tested with Winamp version 2.74 (the
current version at the time of writing). Note that earlier versions of Winamp may not support the
needed functions..

Winamp time code issues
After the initial implementation of the LightJockey/Winamp interface it has been discovered that there
are problems with the time code consistency of Winamp (as some users found out the hard way -
sorry guys). At the time of writing it is not known if there will be a bug fix for Winamp. The problem is
that Winamp gets the time code wrong when playing the audio track - it simply doesn't advance the
current time code with as many milliseconds as it should. The problem affects almost any digital
audio file format (MP3,WMA,WAV) except that MP3 files encoded at 96KBP seems to work just fine.
Experiments show that the problem exists with the following formats:
.MP3 (except for 96KBP encoded files) - Winamp only counts approx. 0.25 second less pr minute.
.WMA : Winamp counts approx. 1.75 seconds less pr. minute (factor may vary)
.WAV : Winamp counts approx. 0.25 seconds less pr. minute
The problem occurs as seek commands (Seek DA or moving the track bar on Winamp) seem to
decode the time correctly. For example: Use a DA seek to position the track in an MP3 track at
around 04:00:00 and let the track play - log a time code at some recognizable event in the track (e.g.
04:05:00). Next let the track play from the beginning - when the track reaches the event the time code
(which was logged at 04:05:00) the time code from Winamp will be at approx 04:04:00 - so the time
code lags about a second after the original log (approx. 0.25 seconds pr minute). Since most time
code synchronized cue lists are made by seeking and logging and fine-tuning to small bits of the
track at a time this poses a real problem as Winamp does not return identical time code when the
track is played from the start.
Partial Fix
Fortunately the time code inconsistency seems to be fairly consistent - at least with regards to MP3
files, which allows at least a partial fix namely multiplying the time code from Winamp with a factor
when playing the full audio track.
Use the fix the following way:
