in a recent scan about 2000 of the 6000 mp3's have no BPM. There are lenghts, and when I load them into a player also a waveform shows up, but NO AUDIO...
What is the problem here?

happened to me a couple of times seems to be a little glich but sorry can't explain what it is just check your gain control on your deck and adjust and manually but in your bpm should then work...does it for me...

Yep, I've had that too, and as tayla says, check your gain control, It took me ages to figure why I couldn't hear the track, then realised it was turning the gain all the way down when i loaded it on a deck.
I accidentally discovered a fix, but I have no idea why this worked. I right clicked the file, selected "file info" then in the box, I clicked the little arrow underneath each entry, after that, it worked fine again!
Don't ask what made me try the above, I have no idea!

Guys,
Thanks for the quick advice and workaround... i'll try it tonight...
My gain control is set to "Always 0 db".... is that any good?

If you are using v5 - what are the bitrates of the files?

cstoll, not sure if it's bitrate related, the one that did it with me was a 320k i think. Now the one that did it was working fine, then i was messing about with the database options etc, then when I played it again, no sound and it's BPM count had gone, no amount of analysing the file would bring the bpm count back, then i realised it was turning the gain knob all the way down. (note to above poster, "always 0db is fine, i use that) When I turned the knob up I could hear the file fine, but still it's bpms weren't listed, I did the thing i listed above, and the bpms suddenly came back and it no longer turned the gain down.

The bitrate varies... Most of the mp3z are 320kb, but also there are some with fluctuations between 192 and 224 kb

I have had the same problem. What I ahd to do was shut VDJ and reopen. SOng in question worked,

Hey TopHouse - it was just to understand if possibly they had some really low quality files that VDJ was having a hard time analyzing.
But your point about the HI Quality could be an issue. If when analyzing the file the gain is so HIGH that VDJ can't best determine the beats and then writes some funky gain adjustment value in the DB then that is a possibility based on your results described. If so, then definitely something that needs to be looked at. Remember most of the common commercial download sites are 192kps quality and usually normalized to 0db. But us rippers know we can get better quality. Might be worth testing by ripping the same song at various qualities and gain structures.

Guys:
I found a pretty good workaround for the problem:
1) Make backup of xml database
2) Scan the files, so that the filter isscanned=0 returns nothing
3)
Open the XML in an editor and perform a search and replace action
search for <FAME IsScanned="1" />
replace with <FAME IsScanned="1" Volume="4455" />
4) Then rescan the files with no bpm
5) Now you have a working MP3, whatever gain or kbps is used..... WITH BPM
Greetz,

In my case, this was a file that was previously working fine in V5, it had previously analysed etc and played. I was messing about with the various "get infos" options with a number of files selected when this particular one lost it's BPM and gain setting. As I said, I don't believe it's the bitrate of the rip, now I'm in an area where i don't know what I'm talking about, BUT Somewhere in an mp3 there must be the data that sets it's DB, (otherwise why does VDJ change gain for different tracks?) Now, I'm thinking that that gain thing is linked somehow to where the BPM is stored in an MP3
OR, (now as I said, I don't know what I'm saying here) What if
Something is corrupting the bit in the file that determines gain. Now what if, when VDJ is scanning this file, because it has no gain, it cannot read any bpm. IE, a soundless file has no bpm.
Do you understand what I'm trying to say? Or am I Way off the mark with my theorising?
P.S Not trying to push your buttons with this one Chris :o)

TopHouse - I know your not pulling my string, but you are exactly on target - though a bit garbled because as you said - not your area of understanding. But, Joop3m I think just proved part of my point and partially answered the issue. If you notice there is no Volume tag in his first example. If he adds a Volume value, then VDJ somehow properly analyzes and finds a BPM the next time around.
Definitely something for the DevTeam. And as for the 'how does VDJ know what the gain structure is?' Well that is one reason for why it analyzes the file to find the variation from 0db so it know what to do with the file based on your AutoGain settings when you load it to play.

I think you are both right...
No volume, no bpm...
Thanks anyway and i hope the dev team has some sort of patch ready he he

Songs bought on Itunes ?
Are you trying to use 2 scanning windows at the same time ?

None of the above, the one that did it for me was a self rip.
Funnily enough could be a different issue but, I have 4 hard drives on my machine :-
1 OS & VDJ
2 Audio
3 Video
4 Karaoke
Now over the last 5 days or so I had analysed all of the above with V5 (making a fresh start what with all the database related probs) Anyway, I did audio last as it's what i have most of & would take longest. The audio finished, i recursed a few times, did the file infos 'get tags from filename' (all my files are named <artist> - <title> ) all well and good, BUT, when I did the 'infos' thing on my karaoke drive, all the BPM's disappeared! The karaoke files are all zipped mp3+g. I'm now analysing them all AGAIN. Any ideas?
