Koz: The light is beginning to shine, about spliting and joining the stereo tracks and amplifying the low track. Thanks. I guess this can be done at any stage of the work but at the beginnning is probably best. Arriving at the "proper" boost (Amplify) level will be a matter experimentation, I guess....

DVDdoug: You're getting pretty technical for me but I'm up to try almost anything. I read the thread about the Wave Stats plugin and am not sure whether there is a "sample limit", or if the newest version of this plugin will crash Audacity. If there is a sample limit, I can't see how this will help ...

Koz:

Thanks for your suggestions. I've never "split" a stereo track so I'll have to experiment. I assume I would use the Effect>Amplify tool on the separated L track and then recombine. In db value does a 5% increase translate into .05 db increase?

Channel Imbalance OS: Vista 64 bit, SP2 Audacity version : 1.3.12 During the recording of a number of stereo vinyl LP records, there seems to be a general L/R channel imbalance of about 5%. This is based purely on observation of the recording meters in Audacity. The R channel is slightly "louder" th...

Thanks for outlining the process. Your link to "Sample Workflow" is very comprehensive. I appreciate your help. The Audacity team has provided an almost overwhelming amount of information in their Wiki pages. Thanks for reminding us of this great asset.

Ignatz: I appreciate your comments. I think one of the things I may have been doing wrong(?), is trying to apply the NR tool to parts of the overall recording (the lead-in on an LP, the spaces between music tracks, the ends of music tracks where I hear noise) rather than a complete side of the LP or...

Ignatz: I don't follow your inference. After noise reduction, you can apply amplfication to overcome the "drop in the loudness of the music". Noise is part of the original signal, so naturally when you remove it, the apparent volume falls . I'm no expert, not even close, and certainly don't know the...

Thanks Ignatz for your suggestions on using a fast fadout as a solution to the end of a noisey music track. I'll give it a try. I have tried using the NR tool witin portions of a music track and even if the "Noies reduction" slider is set low (around 6 or 8) I hear a noticable drop in the loudness o...

I think this topic may have taken an unintended, yet important, change in direction: a discussion of the source and kinds of noise experienced in recording. Of course, Audacity doesn't know what noise is (for the Noise Removal Tool) until you tell it to "Get Noise Profile". There is even some talk n...

stevethefiddle: The .wav file I originally attached with my initial post on this topic was recorded without any record playing at all. The turntable was not "running" at all. As a matter of fact, with the turntable unplugged from the 110v, Audacity still sees this "noise". That's why I referred to i...
