Hello Bryce,
Welcome to librivox. You have a nice clear voice, I had no trouble understanding you.

You need to make change(s) in order to meet Librivox's technical standards.

Required: the quality of the microphone is horrible. It is doing a bunch of signal processing to reduce noise, and doing a really
bad job of it (see my videos below, mics listened to). Do you have an alternative you can try?

Required: There are some noticeable "pops" in the "P" sounds (at 7, 11, 16.4, 22.4, 23.5s). There are some different ways to fix this: 1) move away from the microphone or position in the microphone to the side of your face; or 2) get a "pop" filter in front of your microphone. At its worst, a "pop" maxes out the recording, and you can do nothing after the recording to fix it. If you have a "gentle pop" that is just a minor irritant, often you can apply a high pass filter (from the Effects menu) at about 75Hz, and this will make it far less noticeable.


Please address at least the required technical issue(s) and upload a new version. If you quote this message in your reply, I'll get a notification and will go in and re-check.



If you haven't already, you might spend some time browsing through the LibriVox Wiki. It contains a wealth of great information that you'll find useful and informative about who does what, and various technical aspects.


Thank you for participating in Librivox,
Adrian Stephens

PS - If you're interested in developing your technique, and have the time to spare there's a whole bunch of informative YouTube videos.
Our excellent admin Phil has recorded a lot of highly accessible videos (https://wiki.librivox.org/index.php?title=Instructional_Videos).

I have also recorded a number of YouTube videos on this subject, longer (and thereby going into more detail) than Phil's.

Here is a new recording.

I am not sure if I have a mic that could be loud enough without losing quality. I may just try to get a better mic.

Hello Bryce,

I think you moved away from the mic. However, I'm still picking up breathing into the mic at: 16, 22, 23s. Please listen to these portions to see what I'm talking about.
You can fix this by moving the mic off-axis.

The volume is too low, probably because you moved away from the mic to fix the pops.
You can download the checker program (https://wiki.librivox.org/index.php?title=Checker) which you can use to check the volume against the expected range. This recording was 83 dB, and the normal range is 86-92 dB. You can change the level using Effects / Normalize or Effects / Amplify in Audacity.

The quality of the recording has increased, but the background noise now becomes plainly audible when you amplify it to the correct level.
You can listen to the noise by taking a portion of silence and normalizing it (Effects/Normalize) to that you can hear it clearly. Think to yourself, what is the source of the noise?
There are three things you can try to reduce the background noise. You might need to do more than one of these.
1. Avoid the noise. Move to a quieter room. Turn off the clothes drier. Choose a quieter time of day to record. Set the laptop power settings to "passive cooling".
2. Move closer to the microphone, but watch out for those "p" sounds! You should be about 4 inches (10cm) from the microphone. You will need to position it to the side or use a pop filter.
Use noise reduction using Audacity. You can highlight the noise in Audacity by changing the track's display mode to "Waveform (db)" using the little pulldown arrow just to the right of the track name (prior to 2.4) or in Edit/Preferences/Tracks/Default Waveform scale: Logarithmic (dB) (2.4 on). I recommend leaving it there, as I do all my editing in this mode. Then perform noise cleaning as shown here: https://wiki.librivox.org/index.php/Noise_Cleaning. I recommend making this a part of your editing routine. You'll be surprised how much difference it makes, but be careful of over-doing it (more than about 18dB), which can affect the quality.

These all need to be addressed. I think your best option will be to get another microphone.


Best Regards,
Adrian

Hello Bryce,

This is a good microphone. But you are still popping. Listen to your track at 10.4s. Please step back from the mic by 6" and try again. You can always boost the volume later in Audacity.
The background noise (fan?) is still there. Audacity noise reduction does a good job of removing it.

Adrian

Hello Bryce,

You successfully cured the popps. Sound still high quality.
But you do need to boost the volume:
You can download the checker program (https://wiki.librivox.org/index.php?title=Checker) which you can use to check the volume against the expected range. This recording was 81 dB, and the normal range is 86-92 dB. In Audacity, you can use Effects / Normalize or Effects / Amplify to change the volume post-recording.

You can also afford to be more aggressive with the noise reduction, as the background noise is just about audible.

Best Regardrs,
Adrian Stephens

I used noise reduction and amplify on this track
