Chienworks et al were instrumental in helping me get through several obstacles to good recording. I thank you all. I've been making progress all week.

Next up is the question of what to do when source material is less than ideal. I have here a sample of substantial muffled hum. Please copy and paste the link if html doesn't work. It's only about 300k.

I have no idea how, or even if, this can be rendered more audible. To me, this is the worst kind of noise on pre recorded material. I am hoping that if something can be done to improve this sample, then the process will point me in a direction for solving other types of noise.

Thanks again for your insights.

Well, that's definately a bad recording and I highly doubt much can be done with it. I would start with the Sonic Foundry noise reduction plugin. Any constant noise should be able to be removed, along with the pops and clicks. Then you should do some eqing on what doesn't get removed by the noise reduction so that it doesn't sound so muffled.

I wouldn't look at noise reduction for that file. Sounds like a notch filter would help. Try using the dynamic eq and go from there.

I'll work on it.
