Hi,

I am new to this platform and would like to claim poem no.72 “Try Again” by Anonymous in The Junior Classics Volume 10, part 1: Poems Old and New by William Patten (1868 - 1936).
My one-minute test link is https://librivox.org/uploads/tests/1_minute_test_Kalpana.mp3
The recording was done using Audacity.

Thanks!

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

There's a few technical changes you need to make that will improve the recording and make it acceptable.

FYI, the file name should be all lower-case. This doesn't matter for this test recording, but is a uniform standard for actual recordings.

Required: The file's format is MP3 stereo at variable kb/s. The specification we use for all MP3 recordings in Librivox is mono 128 kb/s constant bit rate. You can set this on the "save as MP3" dialog in Audacity, and it will persist the next time you do a save.
Required: The volume is a little too low. 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 82 dB, and the normal range is 86-92 dB.

Required: There is some noticeable background noise, which can distract from the reading. Please 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. You can also move closer to the mic, this will make a lot of difference - but watch out for those popping "p"s !

Advisory: There is some weird stuff on the entry and some table mic knock on the exit. You should get used to clearing these using Audacity.

Advisory: There is a noticeable room echo. You can reduce this by recording in a room that has a lot of soft furnishings. I hung cheap removal blankets on the walls and ceiling of my shed to create an acoustically dead space for recording. You can also reduce it by speaking closer to the microphone.

Please address at least the required technical issues 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.

Hi Adrian,

Thank you for the feedback on the one-minute recording. Here's what I will look out for.

1. Filename - all lowercase- Noted. Will use the given format in each reading forum.
2. Use mp3 mono, instead of stereo.
3. Recording volume- to increase slightly.
4. Avoid background noise and clean up any persisting background noise.
5. Prevent room echo. Make the room more recording friendly. – Will see what I can do on this.

I will make the changes and resend the link.

Thanks,
Kalpana

Hi Adrian,

Here's the link to my 1-minute recording https://librivox.org/uploads/tests/1_minute_test_kalpana.mp3
I have made the necessary changes. I have taken care to avoid all background and ambient noise as well. Let me know if this works. I am new to audacity and find that there are a few things that I am still trying to fix - for instance - volume is low at the beginning of the recording, and there is still some background noise despite noise reduction. I am trying to understand why this is happening and to fix it. Would greatly appreciate your feedback and thoughts on this.

Thanks,
Kalpana

Hello Kalpana,

There is some weird changes in volume throughout. Are you moving during the reading?
The sound is still very acoustically hard - i.e. lots of echo.
There is no noise. If you did noise reduction, you can dial it back a bit and improve on the "liveness" of the speech.

Please re-record and pay attention to being still and speaking with a constant volume.

Best Regards,
Adrian

Select the area from 6 to 7 seconds and listen to it. This is the sound of excessive noise reduction.

Could you please tell us what computer and exactly what microphone you are using? Not just "USB mic".

Lastly, could you post a raw recording (with a different file name); one that has not been processed in any way. It makes it easier for us to tell you what you need to do.

Thank You

Hello Kalpana,

Agree with audiomike. This is over-processed. If you post the raw file I will experiment with it. Please get as close to the mic as you can without making your "P"s pop. I suspect we will end up suggesting you replace your microphone.

Best Regards,
Adrian

Hi Audiomike/Adrian,

Here's the link to a raw recording - https://librivox.org/uploads/tests/1_minute_test_raw_kalpana.mp3

Audiomike, here's the clarification on the mic used, computer etc.

1. Computer – DELL Latitude E5450

2. I used the Apple earphones (inbuilt) mic to record. That’s the only microphone I use.

3. Original file was recorded on the inbuilt sound recorder (WMA) as recording on Audacity picks up a lot of ambient noise, records at extremely low
volumes, and also causes unexplained volume variation (The mic does not move and nor do I).

4. The Windows Media Audio File format has been changed to an mp3 format

5. Editing done using Audacity.

6. Audacity noise reduction specs –
Noise reduction db – 15
Sensitivity – 6
Frequency smoothing bands – 0
Noise – Reduce

7. Audacity version used – 2.3.3


I hope this helps. Let me know if you need further clarification, I'll be happy to provide it.

Thanks,
Kalpana

There are some unexplained things here, Kalpana.

1. Audacity recording from the same mic sounds completely different to the inbuilt recorder.
2. When I do noise reduction using Audacity (same version) and the same parameters as you, the
result doesn't show the "processed" sound we hear in your processed recordings.

This recording is stereo format, and the noise is marginal. I fixed the format, did noise reduction and amplified it, and the result was perfectly acceptable. I cannot explain either 1 or 2.

Do you want to get online with me and show me exactly what you're doing to process this file? I'm in the UK timezone.

Adrian

Hi Adrian,

Thanks for the clarification. The problem with using audacity is, for some inexplicable reason, the recording plays back at extremely low volumes. I tried all variations but was unable to identify the reason or rectify it.
Infact, the very first recording that I sent was done via the sound recorder. you had mentioned that there was no problem with volume, just some background, and ambient noise, stereo etc.
I guess it would greatly help if we can do this in real-time. I am in the India time zone. I am sure we can find a feasible time slot to check this.
Saturday would be preferable as I will be at work on weekdays. Would Saturday around 2:30 pm UK time (IST 8:00 PM) work for you?

Thanks
Kalpana

Hello Kalpana,
That should work.
I'll PM you with comms details.

Hi Adrian,

Here's the link to my one minute test. I used audacity and it sounds better than the previous audacity. I hope this works :-)

Hello Kalpana,

Well done, you now meet Librivox standards. Proof Listen OK! :thumbs:

I suggest you spend some time becoming familiar with the forum and looking for projects that you think you'd enjoy working on. Just jump right in wherever it feels comfortable. Most of all, always have fun. You'll find lots of interesting material to record. If you're like me, you'll also discover you're learning a lot in the process and being exposed to books I otherwise wouldn't have opened or known about. You'll be contributing to an interesting project and interacting with a lot of fun and varied fellow LibriVox volunteers in the process.


Thank you again for participating in Librivox
