Hiss -Sound Forge - PC - MAGIX Community Forums Archive

Subject:Hiss Posted by: Frogman Date:10/6/2002 12:08:49 AM I used an analog unit to do my actual recording. This really sounded descent. I mastered it onto my PC using Sound Forge 6.0, and it also sounded fine. The original volume going into my computer was as high as possible (the signal was a bit weak), leaving me no other choice but to use the volume feature within the software, but this created a lot of hiss. I screwed around with the noise gate to no avail. Is there an easy way to remove unwanted hiss?
Subject:RE: Hiss Reply by: jgalt Date:10/6/2002 7:23:25 AM Two hiss reduction possibilities come to mind. Both require that a sample of the hiss be taken from a place in the file where no program material exists. 1. The best method requires the Noise Reduction plug-in. I'm assuming you don't have it or you wouldn't have asked the question. 2. Analyze the hiss sample with the Spectrum Analysis tool to determine the frequency and bandwidth of the hiss. Use the Parametric Equalizer tool to construct a filter to eliminate that band of frequencies from the file. The 2nd method will also remove any program material that falls within the same frequency range as the hiss.

Subject:RE: Hiss Reply by: rraud Date:10/10/2002 12:52:05 PM When used correctly the Noise Reduction plug-in will NOT noticably remove any program material that falls within the same frequency range as the hiss. You can actually boost the high-end by adjusting the parameters while attenuating the hiss.
Subject:RE: Hiss Reply by: sk Date:10/10/2002 11:17:46 PM Well, unless the laws of physics have changed, or Noise Reduction 2.0 is smart enough to distinguish the difference between hiss and music at the same or similar frequency, it's my understanding that while the collateral damage can be minimized, it's simply impossible to avoid removing at least SOME of the music/sound along with the hiss. Right Red? lol sk (What's up, Red...cat got your tongue?
