I have been happily using Audacity for several years and finally run into something that I am unable to fix. The sound track on a video I am processing is distorted, probably from too high recording level. I reduced the amplification and that helped a little but the sound is still ‘fuzzy’. I’ve posted a little clip of the original unedited track so you can get an idea of what’s going on. I would have posted a bigger clip but dialup . . . sigh.
I am on Ubuntu (Gutsy with a Hardy kernel) and using Audacity 1.3.4-beta (Unicode).
Thanks for any tips you can offer. (I searched but nothing jumped out at me.)
Or me. It’s not classic clipping from too high a level. I wonder if the performer was wearing a headset that was overloading a radio microphone system. She seems to have the microphone element jammed right in front of her lips–which would have been OK had the system been able to deal with that kind of signal.
Especially because there’s music already mixed in, that’s as good as the show is going to get.
Overload/clipping is one of the four horsemen. Echoes, moving background noise, and extremely low level are the others. No recovery except sometimes in the police investigation sense.
Exactly. Many of the workouts are fine but a few start out like this - very annoying. Things improve a little when they begin to compensate for it. Not really amateurs but definitely not professionals - somewhere in between. You get what you pay for . . .

That means you have a copper phone line. You can get DSL Extreme basic package for $13 a month, unless you live a million miles away from a phone company Central Office.
Kinda the boonies where DSL costs more than $13 a month. Besides my $4/mo dialup seems to be faster than my neighbor’s DSL! Not really into media online - mostly technical forums and plain text lists. (I’m into ‘slow food’ and OTA antennas too.) When I do a major distro upgrade, I can always go to the local computer shop with the big pipe and they hook me up for the duration.
<<<1) can you elaborate a little and give possible remedies>>>
Yes. No.
The Four Horsemen were Strife, War, Famine, and Death. Only Death is mentioned in the Bible, but the others are identified in other texts.
In Audio Land, the four horsemen are the unrecoverable errors. Once you present an audio show with Echoes, Clipping (Overload), Moving Noise, or Seriously Low Level, you’re dead. Over on the video forums, we have a joke that you need to apply the Reshoot Filter. Pick up the camera and shoot it again because you have no show so far.
Typically, you can affect the error with audio tools and you can change the sound, but you can’t make it better. The other thing that happens is you spend weeks fooling with it and the result is awful.

No. None. There is a software package that can patch clipping. What they call clipping is one slight “tick” on an actor’s voice once every half-hour and everything else is smooth and crystal clear. What most users call clipping is a barely recognizable voice in a sea of distortion. Did I just describe your show?
We strongly recommend recording a few seconds before a performance and playing it back to make sure everything works OK.
Cool! My equipment isn’t that fancy. I’ve got several 19" analog CRTs to use up so I’m doing the converter box thing. Here’s my setup.. Currently, I’m pulling in all the local channels on UHF about 26 miles from the towers. It remains to be seen what will happen when FOX moves to VHF in February.
Which towers? I was surprised to learn that nobody in LA, even the techies, watch towers. I knew who owned every tower in each city I lived in including this one.
VHF should have much less trouble climbing over hills. We noted that nobody is scheduled to go back to what Europe calls Band I (channels 2-6).
Low pass filtering with a very sharp filter (24db, 36db) can remove parts of the distortion. If the (undistorted) input signal was too complex the filtering will remove too much from the original signal.
