Soundforge 7.0 & distorted recording

Can anyone give me some tips how to remove distortion in a recording using Soundforge 7.0 or at least reduce it? Any help is welcome!

Is it distortion from heavy clipping? If so, you're pretty much screwed. Search for other threads on this, but if you clipped or brick-walled it bad, there's not much you can do but not run as hot next time around. Running hot is good, but clipping is much worse than running hot is good, so take it easy on the levels...

give the "Vinyl Restoration Tools" a try...

They can perhaps make it bearable to listen to...depending on the nature of the clip...

See, the thing is with heavy clipping, is that the information simply isn't there at all. There is nothing really to restore "restore" -- the tops of the waveforms are flat. There are some tools/plugins that try to round the tops of the clips, but if you've clipped it bad, there's nothing you can really do. The best plugin I've found isn't the vinyl resotration, it's the clip restoration tool in vegas, but that plugin is sold seperately, it won't be in vegas or SF unless you specifially had it and installed it. But not even that will fix it if it's heavily clipped. No worries though, everyone does that AT LEAST once, LOL!

Again thanks alot for the replies, in fact I never knew if there was heavy clipping there is no info :laugh: 
But a question, what's better to use, Vegas or SF?
Me and a friend taped the same show on DAT (me with CSB and that friend with OKMII r) and he is convinced the levels should be more on the right side but I prefer keep them in the middle and my rec. was bassy but not distorted and his one (the one I'm trying to fix now) is somehow distorted so what do you suggest me as a experienced taper?  ;D Levels in the middle or more to the right? I guess it depends what kind of band you tape but what with bands who can make heavy noise?

For two track, and especially if you are comfortable with it already, just use SF. If you are mixing more than two tracks or mixing in video, then Vegas all the way. That said, I always use Vegas because I like to work in a non-destructive way, but let's not go there right now. One thing at a time. For the sounds of it, you might to make sure whether you truely clipped the levels or your mics were brickwalling. They sometimes sound the same, but are in fact two very different problems. Open the file in SF, then look and possible "zoom" into the wavform (I think CRTL-SHIFT up and down arrows will zoom the vertical DB portion and just up/down arrow on their own to zoom in horizontally on the timeline). If you were clipping, the waveform would go all the way to the top and bottom and flatten out on the top and bottom (the flattening is the part that visually shows you that sound data is actually "missing" because it clipped and caused the waveform to flatten where in real life it would not have been flat). If you're mics were brick-walling, then you'd see a similar flattening of the waveforms, but the waveforms would not extent all the way to the top or bottom (they would NOT extend to 0 db like clipping would). If you clipped, then next time, don't run as hot, and as far as the meters, the thing you have to watch out for are the LOUDEST parts, so it's a little more complicated than "in the middle" or "to the right more." If the music gets real quite at times, then gets real loud, the meters will be all over the place and a rule of thumb like to the right won't necessarily work, you have to plan for the LOUDEST sound. On the other hand, if your mics bricked, then lowering the gain won't help next time. You need mics that can either handle louder SPLs or you need to get more power to the mics you have or both. Are you running with a battery box between the mics and the DAT?
