PS...taking small chunks and doing DC offest adj. should never have to be done. Just wondering how this can come in here sounding decent and looking so terrible!

That picture is an entire song. The high pass filtering did no good. I asked for a remix. Seems something in the tracking of the synths caused this..and really, this tune has very little LF info.

Hmm, and it fades to zero at the end.

Zoom in and look at the shape of the waveforms. Maybe they're just really asymmetrical, which would give the appearance of offset when zoomed way out, but in fact have no DC component.

wow  that IS insane

the fact that it is mostly synths has to be a clue.

maybe its something just a little bit up from a DC offset.   A .01 Hz tone being mixed in?

maybe the mod wheel on the synth is stuck a little bit in the 'on' position

You have to push your SoundDesigner skills.... Just draw a wave with the same average shape. Maybe for a start you can EQ it with a low pass and then keep applying Low pass and drawing here and there. Then mix both signals using your new wave with inverted phase. That should cancel the offset a lot.

Ive gotten a file like this from someone who used lots of synths.  Not quite as bad but none the less.  It was solved by going back to the mix and putting a high pass in individual tracks (most).  We cut most at 20 and some that had no real low end content at 60.  The record sounded cleaner anyway and everyone was happy we did it.

Play it out onto tape or thru some 1272s or similar then back in again.

You might try to segment the file and aply DC removal filter individually, then reglue the whole shit back together.

damn, this is something

Thank you for all the advice. I went back to the producer and we opened the file on his system. It looked good and he sent it to me via FTP. Something went wrong in the burn to CD originally. I am placing the blame on the A/C chain and/or poor media.

The key would have been to actually try the CD before leaving the producers desk.
