Audacity Forum

What has been worrying me is the the red bars sometimes seem to max out. That is an overload condition and is to be avoided. It produces permanently damaged sound on a recording (but not during editing). The other extreme is recording with the meters down in -30 or -40. That's too close to the quie...

The meters and the blue waves measure the same thing differently. The meters are in dB which is similar to the way your ears work. The blue waves are in percent which makes it a bit easier to edit. 50% is -6dB. 25% is -12dB. You can extend that idea which means the blue waves start to "run out&...

Here's one I shot yesterday. The silent part is at the beginning. Raw shoot and filtered for ACX conformance. I have a hum in my "studio" that I need to run down.

Do I need to acquire a shock mount? Yes. If you don't, the mic will pickup noises from the floor. I recently did a sound test without one and I found floorboards that make mic noises but aren't apparent to the ear. Also the pop filter. I recorded a "quiet" sample and then did a plot analy...

While I think its a terrific idea to try and clean up these tapes, as a practical matter you will probably not be able to do much good. There are ways to even out the volumes between the two performers on a clean tape. Not a tape with hiss. Have you ever tried to get rid of hiss? Noise Removal does ...

I shall try and re-record one of the tapes again with those levels that you suggest and try and put it on to a CD again. Actually, you should do another capture and listen to it in the computer by playing it in Audacity. If it's humming there, then making a CD will do no good. There's another part ...

OK. You already have a Shure SM58 microphone and cable, right? So you need the stuff between that and the computer. You may need to resize your browser screen to see some of these pictures. I customize the most used ones for the forum, but some of them are wide screen grabs and will not fit well. Th...

FM sound only goes to 15 KHz, so you can safely strip off everything above that. Effect > Low Pass Filter. A real stereo FM receiver would be doing that for you. You are looking at the pilot and 38KHz stereo separation signal leakage.

I'm not actually done, but I thought I'd post what I have. The raw clip is an ES-58 microphone (Shure SM58 knockoff), a Peavey PV6 analog sound mixer and a UCA-202 digitizer. Computer is largely unimportant. I will admit I shot this at night and I waited until the traffic died down. The patched clip...

The clip Koz asked for is #96, sixth post on this page:

Thank you. I have to do this on a machine with a good sound system.
