Audacity Forum

What version of Audacity are you running? AUP3 is new starting with version 3.0.0.

If you don't NEED an Audacity project file, ask the student to turn-in a regular audio file (MP3 or WAV, etc.).

I can't listen right now but since nobody has responded yet... Hum or buzz could be a bad microphone cable. If moving the cable around changes the buzz the cable is probably bad (maybe a broken ground/shield connection). Or if you have a different cable, just try it. Of course boosting the volume al...

Books have been written for that. ;) If the whole band is playing at the same time you'll need a multichannel interface, and of course multiple microphones. You'll probably want at least 2 mics on the drums and maybe more. Here is some information about multi-track recording. You'll need to separate...

When you adjust the levels linearly (such as RMS normalizing) EVERYTHING is adjusted up or down by the same amount. If you boost by 6dB, the peak, RMS, and noise all go-up by 6dB. Limiting "pushes down" the peaks and it should have almost no effect on the RMS or noise levels. It should be no problem...

As far as I know, ACX doesn't do any processing but of course they require your file to meet their loudness and noise standards. Now, the reason ACX doesn't encourage the use of a noise gate is because... I assume it's because a noise gate will "hide" the noise in your recording from their automatic...

Is there a another gain to XLR than to mono Jack? Not "mono", "unbalanced". ;) A single mic is mono (unless it's a rare stereo mic that picks-up directional left & right sounds separately). A TRS connection has two signal lines (plus a ground) that can either be balanced mono or un-balanced stereo ...

Also: A someone on internet said that phantom power gives more signal gain compare to a battery (48V vs 1.5V). I am not sure if that is true. Not true.* Some microphones are more sensitive than others but they typically put-out a few millivolts (also depending on the loudness of the sound). Condens...

It sounds fine DC is zero Hz so you can't hear it (and it's probably filtered-out in your soundcard or amplifier, etc.). However, you'll hear a "click" or a "pop" at the beginning & end or when you start/stop playback or anytime the signal suddenly "jumps up" from zero. If you filter-out the offset...

What else could it be?

Did you try the left/right experiment?
