Greetings,

Below is my 1-minute test. I am using Audacity 2.2.2, on Mac OS X Yosemite, with a Samson Go Mic.

I will appreciate any feedback you can give me.
Thanks.
Tom Cooper

Hello Tom,
Welcome to LV!

There are a few things to work out but they aren't too challenging. First, we need to do a little bit of noise cleaning. Do you see how your line during the "silent" areas is "fuzzy"? This is a visual indicator there is too much background noise. In the future be sure that you turn off everything you can hear before you start recording. Sit quietly in your recording area and just listen. If you can hear it, so can the microphone.

For this recording try some noise cleaning. Noise cleaning and amplifying are the two most common edits we do.
First highlight some of your "silence", say 0:30-0:34.
Effect>Noise Reduction>Get Noise Profile
Select your entire recording
Effect>Noise Reduction>Play around with the noise settings (using the "preview" button until you are satisfied). I used 20, 6.00, 6. Toggle to reduce noise>OK.
See how the line in your silence areas became a very fine line? That's what you are looking for.

Next, we need to lower your volume a little bit. You are at 94.2dB. We aim for 89dB with an acceptable range of 86-92dB.
Effect>Amplify>-5 (don't forget the minus sign)>ok.

Finally, some of your export settings are not on target. The good news is with Audacity when you get them set, the program remembers them for future exports.
File>Export audio>(wherever you want to save it is fine).
Bit rate should be 'Constant'
Quality 128kbps
Save

Please upload the modified file and post another link to this same thread for a double check.

In case you are a visual learner here are some videos which may help. They aren't your version of Audacity but should still prove helpful.

Thanks, Linny. I fixed the export settings and reset my record volume to 50 (had it set at 60 before). But I did not use noise reduction, instead setting up in a new location. Hope that this new file works.

Hi Tom,
Much better. :thumbs: All settings are correct now. You are at 91.7dB so be careful you don't go any louder. You still need to do a little noise cleaning. Give that a try with the instructions in my the last post. Please post the edited file here for a final look.

Noise reduction is cool. :) Many thanks, Linny for helping me go forward with increased confidence.
