Thank you for your help :)
I have a logitech headset at present, that plugs into the headset jack, so I think I've checked all the boxes for "least desirable mic arrangement." :/ I did amplify this file a bit because I was having trouble with the volume of the recording. I expect to sometimes have access to my dear husband's nice dictation mic. You can tell me if I just need to wait for that before recording for a project. :thumbs:

Hi and welcome to Librivox. Your reading is great there are just some edits needed please.

The volume is 84dB which is too low. We aim for between 86-92 dB but ideally we would like it to be at 89 dB.
In Audacity you will also find the option to amplify under 'effects'.
How to amplify in Audacity:
If you like you can use the checker tool to verify volume and other settings.

It would help if you could remove some of the background noise to do this carry out the following.

Step 1 - Select a piece of background noise
Select a piece of background noise (no speech, breaths or other noises) in your audio.
In Menu click: Effect > Noise Reduction... A dialog will pop up.
Click "Get Noise Profile" The dialog box will close instantly.

Step 2 - Noise Reduction
Press CTRL-A / Command-A to select your complete recording.
In Menu click: Effect > Noise Reduction... again. Note: don't select "Repeat Noise Reduction" -- that instantly applies the default settings; you want to adjust the settings and preview the results before you apply the noise filters.

Set Noise Reduction (dB) to 12
Set sensitivity to 6.00
Set frequency smoothing bands to 3
Choose Noise: Reduce
Click ok
This should solve the problem. Always make sure you listen to files through headphones so that you can notice any background noise that needs removing. I have tried this setting on your file and it works. It would be good for you to do this yourself so that you can hear the difference.

Please could you carry out the edits then upload the file using the same file name. If you need any more help please just ask. Thanks

Thank you very much for your help and instructions. I'm having input volume problems, and have tried to address these in a few ways, but I'm woefully ignorant about this stuff. I'll explain what I've done. I'm hoping you might have some more advice. :help:

1. I applied noise reduction in audacity to my test recording, and seemed to have success.
2. I had already amplified my test recording in audacity, even before you listened. I tried amplifying it again, attempting to make sure my highest peak did not go higher than recommended.
3. I downloaded Checker, and it told me the file volume was out of range, but it did not tell me if the volume was too low or too high. (I kind of thought it would tell me if the problem was one or the other....)
4. I decided to start over, and borrowed a Blue Snowball desk top mic (plugs into USB), instead of using my Logitech headset. I hooked up the snowball, adjusted the sound settings and so forth, and tested it.
5. I made a new 1 Minute Recording. My volume profile, or whatever you call it, still doesn't look right in audacity. The volume is still too low.
6. I downloaded MP3Gain, as recommended by Checker. First I applied noise reduction to my new recording, using audacity. Then I used Gain to raise the volume level (which was in the 70s) to around 89. It worked, but now I hear distortion in the new recording, presumably because it had originally been so quiet. (See link below.)

I have a new Lenovo ideapad and am running Windows 10. Since both mics (headset and snowball) seem to be recording at very low volume (even though I've adjusted mic volume slider in settings) I'm not sure what else to do.

Thank you for your patience and any additional feedback you might share!!!

Ok, tried again with blue snowball mic about 6 inches from my mouth. Put it through MP3Gain again, and I don't hear the same distortion. Thanks!
