Below is the link for a repeated one minute test in a new location. I believe that it was satisfactory but let me know if it is not and I will make the necessary adjustments.

Joshua, I've viewed your test file and the volume is too low at 77.8 db, a noise level of 43.9 dB (which will increase with amplifying) and a DC bias of -11.
These items will need to be addressed before submitting a file for this project. Better to correct now than with a longer recording. :wink:

Are you using Audacity? I'm going to assume you are. :)

To fix the volume issue, please try moving your microphone slider in the Audacity window up 1 full notch. (If it's at 0.75 now, move it up to 0.85.) This is just a rough guess as to how much to change it; it may need a little more adjustment depending on the result.

For noise reduction, here are a couple resources:
text instructions: http://wiki.librivox.org/index.php/Noisecleaning_With_Pics
video, but with an older version of Audacity so the settings are different: http://www.youtube.com/watch?v=VFSg9o37HMw

My settings are as follows:
Noise reduction: 10-16 (I suggest about 12 for you)
Sensitivity: 6
Frequency Smoothing: 6

I don't think the DC offset is bad enough to warrant fixing. (It's something you'd have to fix on every single file you make.) However, at the very beginning of your file, you have a funky waveform that jumps, then settles down right before you speak. It's really noticeable if you amplify the entire file. If it stays small after increasing your mic input, then don't worry about it. But if it gets bigger, you'll want to leave more of a space when you start the recording before speaking, then come back later and cut out the weird jump.

Try making these adjustments, then post another test. Use the same file name as your previous one, and post in this same thread when it's ready. :)

Sorry about the delay, I had a course for school that required long hours over the weekend. Below is the link to a repeated test. I have amplified, removed the strange swoop of noise from the start (every recording I have done has that for some reason) and noise reduced. Let me know if it still needs work. Thank you for the input thus far.

Hmm. There's still a fair amount of background noise. The rest is OK, though. It's a little loud - try not to get any louder - but with maybe one more pass of noise reduction, it'll lower the volume enough to put it in range, anyway. :)

Could you apply another round of noise reduction - both steps, including getting another noise profile - and upload that result?

You're almost there!

Round 2, I believe I was able to reduce amplification as well.

Whatever you did here, do it for all your recordings, and you'll be golden. 8-)

You're all set - have fun!
