Subject:changing volume Posted by: mheath0873 Date:2/26/2009 3:36:34 PM I recorded an event (professionally) on an HD camcorder recently and was using 2 microphones. One was a wireless and worked great but when I faded to the other mic, the volume is much too low on the recording and I am wondering if it is possible to increase the volume of that section of the video and have it sound good. I have SOny Vegas Platinum and Sound Forge. When I opened the section of audio in sound forge and tried raising the volume, and played it back it would go in an out and sounded terrible. I am no audio expert and using Forge is quite new and difficult for me. Can anyone help me so that I can get this event edited and finished soon. Thanks in advance.

Subject:RE: changing volume Reply by: drbam Date:2/27/2009 6:11:39 AM What you describe regarding the "other" mic sounds like there was a problem with that mic and/or a connection issue. If it is a battery powered mic (electret), possibly the battery could be very low. There are several possibilities but the bottom line is that if the audio file has drop outs, you won't be able to do anything about it. The volume changes can be tweaked but if these were caused by any of the above, then the sound quality of the file will change in those areas as well and that would require that you hire a true audio specialist in order to fix - assuming it can be fixed.

(See oF1 Help). This will give maximum level without clipping. If it still sounds bad, then chances are the original sound is bad, but is now simply louder and thus more offensive. Check the microphone in question, and the level setting for it on the cam. geoff.
Subject:RE: changing volume Reply by: Chvad SB Date:2/28/2009 1:39:14 PM the problem is... when your recording is too low there is a large disparity between your recorded signal and the noise floor of the recording. You bring the volume up to hear the recorded signal, you also bring up the noise. As mentioned earlier, you can normalize the file to get a signal loud enough to work with... normalize to PEAK, not RMS... that will just mess with the next step. After bringing up your signal use the noise reduction plug to try and get rid of some of that noise. Being conservative with the noise reduction and running the process a couple of times is better that attacking hard once... the latter will give you a lot more artifacting.
