Can anyone tell me why when I upload my song to Mp3.com the broadband version of the song is fine, but when they create a lo-fi copy of it, the drum and bass tracks I created on fruity loops are left out, only leaving my guitar and vocal tracks I recorded on CEP 2. Can someone help me out? Thanks.

That sounds like it could be a pretty lo-fi mix to me! :D

Seriously, what exactly did you submit to them? I don't know exactly what they do, but we might be able to work out what's happening from the layout of your source file...

The lo-Fi play is done in mono. This would indicate that you probably inverted one channel in the drum and bass mix (maybe to fatten up the sound). When mixed down to mono, the channels cancel each other out.

I use only a single wav file for for my drum and bass tracks which i export from Fruity loops to CEP2 at 16 bits (although I just realized fruity loops had a 32 bit export especially for CEP). I record my guitars and vocals on CEP at 16 bits, pre mix at 32(I dunno why, it was set that way) and play at 16 bits. I use a dbpoweramp (LAME converter) to convert my song into a 128 kbps mp3. But when I upload to Mp3.com, the orignal version that they play on Broadband is fine, but the guitar and vocals are the only you can hear when they create a lo fi version of the song. My entire fruity loops and cep files are all in stereo too. So can someone help me out, please?

ps, nothing was inverted.

Do you know their definition of "lo-fi"? You should be able to create an MP3 of the same bitrate, etc. to see if yours comes out any different than theirs.

It may be a single wave file but you say the Fruity Loops tracks are stereo. I still beleive it might be a phase cancelation problem. Try this. Open just the bass or drum wave file in cool Edit. Go to Effects, Amplitude, Channel Mixer. Select the "Average" preset and apply it. Did the waveforms flatline?

You might also want to try this with the final mixed mp3 you sent to MP3.com.

Thanks,

The phase cancelation was exactly what it was. Now how do I fix it? Hopefully it's something easy.

I imagine the problem is with the FL tracks. You'll have to back to the originals and see where the phase inversion took place. I doubt if the software produced tracks like this, so you probably did it when you mixed down. An alternative might be a cabling problem, but that's a longer (and less likely) shot.

Whatever, I'm afraid you're going to have to remix the whole thing properly.... and don't forget to check it in mono before you wrap the project up!

Fixing the problem at the source is definatly the best way to go. However, if you already have the drum and bass tracks the way you want them (other then the inversion problem) you could try repairing them in CEP. Open just the bass track in the editing window, move your cursor to the upper part of the left wave or the lower part of the right wave until you see a small L or R next to the cursor. Double click and this will hightlight just one channel. Now go to Effects, Invert and click it. This will put the two channels back in phase with each other. Now do the same with the drum track.
