Just because we haven't nailed this down yet, your symptoms could be a monitoring problem. "I have blue waves but no sound." Download this short test file and play it. The fourth segment should sound a little weird, but you should hear it. If it vanishes, then your speaker system may have ...

I had this on a test Windows machine and it turned out one of the other engineers had left Windows "concert hall effects" running.

Are you using the latest Audacity version? Currently I think 2.0.2? Older versions of Audacity would do that. http://audacityteam.org/download/ When you have a simple, short track and try to do a complex effect or filter, the room Audacity takes inside the computer explodes into multiple times the s...

lining out of my guitar amp straight into the computer. Your moons and stars lined up. That usually doesn't work for most people. The pink sensitive Mic-In on most soundcards will not accept a powerful signal from a guitar amplifier without distortion. but due to the nature of the music I'm trying ...

There's a series of interconnected problems. The original problem was almost certainly your hard drive filling up or a bloated operating system, minimum hardware problems or a fragmented hard drive. Once Windows fails to find enough room to work, it falls face-first in the mud. Then you upgraded the...

Yes, if you have very low frequency thumping from something in the show, that's the end of automated tools and easy solutions. Somebody would have to write code to do that, and then there will only be one customer.

Of course you could just go around them by applying a high pass filter around 100Hz - 12dB. If you had trouble hearing them before, they should almost vanish if you do that. Juggle the values a bit. This is the kind of thing we minimize by applying the filter at the time of recording -- particularly...

It does sound like gunshots.

Apply a low pass filter of 120Hz at 24dB per octave. Select that one sharp spike in the middle and delete it.

Effect > Amplify > OK.

That should give you the display in the picture. All those spikes are booms.

In addition to not being able to remove echo (reverb), you can't split the voice from the rest of the performance, either. And even if you could, you couldn't make a new MP3 out of it for your personal music player. The increase in bubbly compression damage would kill you. Downloaded songs are one w...
