Chris (either of you) Scott, or dobro... help please.

[Change of POETS]

Okay... I have the most annoying issue with CEP. EVERYTIME I convert a .wav file to an .mp3 file, I get a *pop* at the begining of the song... it usually ends up being in the silent part before the track starts, and I then ahave to silence the *pop* with CEP and save the file again... but sometimes, if I don't leave enough dead space before the track starts, it will get into the track itself...

Can anyone explain why? It's really frustrating to have to do extra work because of this....

Thanks.

That's one I can't say I've run across. If I were you, though, I'd start adding a couple of seconds of silence at the beginning of all the .wav files before you convert them to mp3.

In Single Edit View:
1. Put your cursor at the beginning of the .wav file;
2. hit "Generate" ---> "Silence" and enter 2 seconds.

Seems like a hassle, but I just don't know why it would be doing that?

I take it you're taking a .wav file that you've already saved as a .wav file, and then doing "save as" and renaming it and saving it as an mp3. The only thing I can think of is if you're converting it from 48000 to 41000 somewhere in the process, b/c I've hit a couple of snags with other peoples' files that I've gotten in 48000, but I'm really just guessing.

I think I remember something about that problem from a long time ago on the Syntrillium board. I don't remember the fix, but I remember there being one.

I've had a parallel problem. I make beat tracks in Fruity Loops and then ship them into Cool. No problems. But when I make mixdowns of those sessions, sometimes the first beat at the beginning of the song is missing. This happens when I program the Fruity Loops track to start right at the beginning of the track. However, when I leave some quiet time at the start of the Fruity track and then bung it into Cool and edit the excess away in Cool, the problem never happens. So, I think Chris' idea is a good one - try getting some silence at the beginning of your tracks.

Actually, it happens if I "Save Mixdown As" or if I convert a .wav file that's already mixed.

The weird thing is, it happens nearly everytime... but, if I convert from MP3 to WAV, it doesn't happen then... I don't get it.

Thanks for the tip... I'll try it tonight.

dobro... if you ever remember what the fix is, I'd sure appreciate any info on it.

Thanks guys.

Hi Brian-
It sounds like you've got some info at the beginning. When you mess with digital audio, if you start playing any file that doesn't begin with a sample and bit value of 0, then you get a wicked pop. Im sure you've experienced this while truncating samples and whatnot.

MP3 compression eliminates the masked frequencies, somehow, and Im sure it must be the culprit. Im guessing it adds some samples somewhere whether you want it to or not.

I've run into the same problem as Dobro with FruityLoops. I'm always sure to include two or four measures of countoff (hi hats, usually), which I just trim once I've saved a mixdown. Plus, it really helps if you're adding live tracks to sequenced beats and what not. (I know you're using your triton, but others who might be reading might go the soft sampler route)

The best way I can think of is to add some silence at the beginning, and then do a fade it on the silence. I know it sounds rediculous, but there could be some noise somewhere in there that's gone undetected.

Holla back with the results

Peace
Chris
