In a live performance with orchestra and chorus we had trouble with a C-24 mike. One channel was hotter than expected and clipped the loud passages -- failing hardware is suspected. We think perhaps the preamp was overloaded. The clipping took place not at 0 but at -6 db. At any rate, we have the severe distortion caused by clipping in one channel only. This performance was a one-time-only event, and we want to do what we can to recover what we can. Here is the question: Has any software been developed that attempts to analyze the square waves of a clipped recording and tries to reconstruct the rounded "tips" of each wave that have been sliced off? |

See post 1834-1838, Unfortunately you've probably gotten a lesson hard learned. Here's my recommendation,when you set levels of live instruments, you should always aim for -6dB, it might have saved you in this instance of equipment failure. -6dB will allow for your sound source to double in volume and still not distort and will still give you a very good signal to noise ratio. Well, at least you still have one good channel, just gonna have to do without stereo. Suppose you could use a mono channel and add a 6mS delay to one side to give you a pseudo stereo effect.

I thought I'd share the answer I got from Ethan Winer at CServe recording forum: www.analogx.com, download freeware DXman. Works like a champ.

You can try the Clipped Peak Restoration tool in the Sonic Foundry Noise Reduction DirectX plugin. A demo can be downloaded from this site that will let you test it out in Sound Forge or Vegas. If it doesn't work on a first pass (which it might, since it should try to detect a clip level), try this: 1- Normalize the clipped channel so that the peak is at 0dB 2- run Clipped Peak Restoration on that channel 3- Lower the volume back to the original level If that doesn't work, you might need to boost the clipped just a bit more after Normalizing (say +0.3dB) so that they really do re-clip. Then apply Clipped Peak Restoration. If that doesn't work...well, you have some seriously distorted material that needs to be re-recorded.

Any DX plug-ins installed on your computer will show up in the DX menu. As far as I know, the only way to remove from the DX menu is to remove from the computer. Do this via Control Panel|Add/Remove programs. The next time you try to access the removed items, SF will alert you and ask if you want to continue to run these in the future. Say No and be on your way.

Hey Rick, This might be of some use to you: http://www.sonicspot.com/analogxdxman/analogxdxman.htm Thump Rick Zentmeyer wrote: >>Does anyone know a way to remove plug-ins from the DIRECT- X >>menu ? >> >>I have Forge and VegasAudio, using the Vegas Track EQ and >>Track Compressor primarily. >> >>After installing Cakewalk's Pyro CD Burning Prog, I now >>have DIRECT-X and DIRECT-X(1) menu selections in SF4.5, >>with 20 or 30 plug-ins, most of which I have no use for. >> >>I would like to get rid of most of them, not just the CW >>ones, but others I never use. >> >>Any ideas ? >> >>Thanks in advance ! >> >>Regards, >>Rick Z |

Open the plugin you want to remove and right click in the title bar area. Select Properties and then Remove in the resulting dialog. This will unregister _all_ plugins included in that .dll, so they won't show up in other apps either (need to restart in Forge). Alternatively, you can drag-and-drop the plugin .dll onto Sound Forge and click 'No' to unregister them. Note that this will unregister the plugins but will not remove the .dll like an uninstaller. If you want them back, just drag the .dll onto one of our DX apps and select 'Yes'. J.
