Here's one of my Startechs with an Olympus TP7 that I use to record telephone calls. http://kozco.com/tech/audacity/pix/olympus_TP7Blowup.jpg It does that just fine as well as other marginal sound tasks. If the job is important, I drag out the full-on formal sound mixer and microphones. My Mac has a...

Painting with verbs. One of the baseline understandings for digital audio is that the numbering system seems to go backwards. Zero dB is the reference point. If you try to go louder than that the digitizing system runs out of numbers and starts eating the show. Blood everywhere. There are exotic exc...

You were recording your voice and the Skype error leakage from everyone else. It's a common problem. Skype is very difficult to record. This is where I would point you to any one of a number of Skype recording programs... for Windows. For Mac I would be Googling just like you. I do it with two Macs....

See if there's anything in that which can help.

In English, I believe that with a little gentle noise reduction, that last clip would pass ACX Audiobook Compliance. Not by much and there will be an insane urge to apply tools and corrections just because they're cool, not because they're required. And it's our perception of Audiobook specification...

I got Steve's Noise Floor Tester to reveal -50 noise floor. In an earlier clip, I successfully applied a 12dB noise reduction, so that puts the delivered noise floor at -62.

Let's see. What else? Those were the biggies, right?

The clip I tested passes the ACX RMS volume spec — barely.

That last posting very nearly passes ACX peak volume specifications just sitting there. 2.8dB. The spec is 3.0. Easily correctable. One serious restriction of Noise Removal is that the Profile step where you tell Audacity what noise you're trying to manage has to be in the same environment as the sh...

That's impressive. I'm having to work to find anything wrong with it. Is that speaking through your black tennis racket, or did you just move the microphone up? Please note most of the peaks hover around 50% with occasional peaks a bit over and nobody hits 100% anywhere. Check. No odd sounds, crashi...

Cool. Baby steps. Turn on the Alesis mixer. Don't connect anything other than the power supply. No computer, no Audacity. Make sure you have the little green power light toward the right. Reach around back and turn the Phantom Power off. Plug your EV microphone into position one with an appropriate ...
