I found some flaws in the recording. The important news is they all should be fixable.
Audio levels are 2.9 dB above the LibriVox maximum. Lowering the volume of the entire chapter by 5 dB should put you very close to the center of the allowable range.
Clipping occurs at many places in the recording. I think you can get away with simply lowering the audio levels, as the clipping doesn't sound too horrible. Audacity can be set to show where your recording is clipping in the track panel. In my version of Audacity this is in the View menu => Show Clipping (On/Off) - when it's on spots where clipping occur are marked in hard-to-miss red.
There is no silence at the beginning of the recording. Also, I believe about half of the initial word "Chapter" is cut off. There should be about 1/2 second before the first word. Hint: you could borrow a bit of silence and the word "Chapter" from the second time you read it just before the title.
There is a loud sound just at the end of the recording. Since there is almost 8 seconds after "End of Chapter 7." you could trim that closing silence down to 5 seconds and get rid of that final blast of sound.
Also a couple notes for you in future recordings - neither of these are show stoppers but are nice to avoid.
At 3:17 there is a puff of breath into the microphone on the P in 'chicken coup'. Placing the mic so it isn't directly in front of your mouth can avoid this.
From about 5:40 to 6:35 there is quite a bit of rumble in your recording. Sometimes this sort of sound comes from a refrigerator or something in your household. It may be possible to change where (or when) you record to avoid external noisemakers.
I'm marking the chapter See PL notes
- once you've re-upload after lowering the overall volume and adjusting the beginning and end of the recording it should be OK.
