Hello listeners!

This is my one minute test:

https://librivox.org/uploads/tests/test_rafeball.mp3

Recorded on Audacity, Windows 10, with a Blue Yeti USB mic. Not sure if it may need some noise reduction - my house has an air circulation system that has a constant low hum, not sure if the mic picked that up. It passed on a run through checker though, so fingers crossed it's not too far off!

Thank you for your time.

- Rafe

Hi rafeball. Welcome to LibriVox.

You are very close! You could back off a db or two on your volume, and yes I do hear some background noise (also noted in Checker).

You have a number of plosives on consonants which occur when your breath hits the microphone as you speak. Try moving your microphone a little to one side or just below or above your mouth when speaking to eliminate these from your recordings. You also may just be a little too close to the mic. Please try adjusting your mic placement and upload another test. I would also suggest trying a pass of noise reduction as well. Just post the link to this same thread to keep all your tests together.

Thanks Jo - I've tried repositioning the mic more to the side, and applied a light pass of noise reduction (6db), please let me know if that's done the job or if I need to increase that.

Hi Rafe,

Mic position and volume are both good. Background is actually a bit louder in this one. Try this -

First remove the low frequency (120Hz) hum with a single band parametric filter, and then run the noise reduction (using a sample from the end of the file for the noise profile) with the default settings of 12,6,6.

Startng from your second test, that gave me this:

See what you think. You have a great reading voice, btw! :)

Thanks Jo, that sounds good! And thank you for the compliment :-)

I’ll do another 1-min test tomorrow (little one is asleep now), apply that filter and NR and upload for another check.

Take 3, with the single band parametric filter (run at 120Hz, 0.1 bandwidth and -30db gain - please let me know if I should change that gain figure) and the slightly higher NR at 12/6/6 that was recommended:

Thanks for all your help Jo, that’s great! I’m planning on recording something for the short horror or sci-fi collections this week :-)
