Audacity Forum

*Update* i fugured out where the buzzing noise is coming from. Its from the lights switches being on around the house. if there on i get loud buzzing noise. and if there off i get a very low buzzing noise. Wut i have done is connect my computer to another outlet and this seems to have fixed the problem. i dont get any buzzing noise anymore.... Im going to play around with the recording and see how everything goes.

Move before the house burns down.

Normal house wiring shouldn't do that. If your dimmers are getting into the audio, then you have a ground wire loose or broken inside the wall--or at one of the outlets. It's possible if the house is old enough, you may not even have ground wires. My original house didn't.

Do you have ground lifters or ground adapters around your PC power or other audio equipment? Can you "turn the plug over" because it's only using two prongs instead of three?

I had one room in this house where the actual socket was wired backwards and was a shock hazard.

Visit the hardware store and spend a couple of bucks on one of these socket testers.

That's assuming you're in the US. Your mileage may vary. The right lights should come on when you plug this thing into all your outlets. There are no safe exceptions.

Lol no kidding, huh?

can you please explain wut your mean here? Im not too good with electrical stuff. i dont know what your talking about.

I havent checked out the outlets yet. I did some testing. I burned a song from a cd to my computer then i used the same cd and same song and i recorded thru my mixer using audacity to my computer and it doesnt sound as clean and as loud as when i burned it to my computer. its almost like it lost its 3d sound and it has 2d sound now. it kind of sounds a bit flat. Can someone tell me why this is? Here are the files so you can listen to them...the first file is from the cd that i burned to the computer. the second file is the one i recorded to the computer. the first file sounds alot better.

original.wav - 5.79MB


record.wav - 3.37MB

Even before I listen to it, Audacity wakes up from first birthday in Mono. You need to go into preferences to change it to stereo, and then restart Audacity.

I bet one of those files (the flat one) is going to be mono and the other stereo. I'm takin' bets.

Koz

Sure enough. Please also note that the "flat" one is half the size of the stereo one. One is a single audio track and the other is two.

Koz

I sure did have it on mono. thanks! it sounds alot closer to the original. not as good but good enuff. i guess ill settle for that. it just sounds a bit lower than the original. Thank you for your time...much appreciated.

To get an exact match, you need to be in at least 48 KHz sample rate, 16 bis instead of 44.1 KHz and the volumes of the two performances have to match. Your ear changes things around a bit when the volume goes up and down and it's not pretty.

Salespeople used to sell really cheap stereos by making them louder and distorting them slightly. Distortion sounds loud--until your ears fall off--but that doesn't happen until much later. After you get the system home.

Koz was asking if you have a three pronged plug that your computer gets it's power from, or if it just has two prongs. It really should have 3 (two slotted ones and a round one).

I'm not sure if you're actually in danger or not, but it's possible. Light dimmers do normally generate electrical noise, so you might not actually have any problems, but it's still possible that your electrical ground is screwed up (this would not be good).

You can go to the hardware store and buy an electric socket tester, it should cost no more than $10 and will give you piece of mind if you test all the sockets in your house. As an electrical engineer, I recommend everyone do this.

Also, is your computer plugged into a power strip, or plugged directly into the wall?

i have the three.

My computer is not connected directly to the wall. its connected to a power strip.

for 48 KHz sample rate, you mean 48000Hz ? under preferences, quality tab under default sample rate right? 16 bis instead of 44.1Khz? where do i switch that?
