sfk files

Sometimes my program saves avi files as an "sfk" file. I have no idea how this happens, but it is not recognized by any media players and does not allow me to preview the file or copy it to disk. Trying to delete the file extension does no good. I have read that an sfk file is associated with sound forge which is the audio editorfor SB. Also it seems that if you choose a different audio editor under preferences that it will not save the adjusted audio file. Does sound forge have any downloadable plug ins? The ones provided with the program are weak. Right now I'm trying to eliminate air conditioner hiss. Thanks a bunch...

The .sfk file is a picture of the audio waveform that you see on the timeline. It saves this file on your drive so that you can scroll through the timeline much faster instead of having to wait for the display to be created every time you scroll. Any file that contains sound will have a .sfk file created when it is used in any SONY media software program, ie. you'll get them from .avi files as well as from .wav files in both Sound Forge and Media Studio. You can delete them if you wish, but they will be created again the next time you use the media file.

If you want to eliminate a constant noise like air conditioner hiss then the best thing to use is SONY's Noise Reduction plugin. It's fantastic and gets rid of almost all noise like that. The bad news is that it's $279, and it only works in the full "pro" versions of the software like Vegas or Sound Forge. It can't be used in the screenblast versions.

Constant noises are relatively easy to remove, though there's always the risk of leaving processing artifacts - the audio can have a "metalic" sound to it. Acoustica can do a good job and it's only $29 for the latest version. It's also available as a trial.

When you use an external editor you need to select the option to edit a copy of the audio clip - this is automaticaly inserted into the time line to replace the original.
