Test Recording for Juan Carrion
Welcome Juan
All your technical settings correct, so well done. There is however a bit too much background noise. It sounds mechanical like a PC fan.
Try to isolate your mic from the noise, such as computer fan. If that isn’t entirely successful, use Audacity’s Noise Removal filter to reduce the background noise about 10dB. Noise removal instructions are available here: https://wiki.librivox.org/index.php?title=Noise_Cleaning. A video tutorial on Audacity noise removal is available here: https://youtu.be/rvhqw7zBmEo
Checker can test background noise. With Checker open, go to Validation>Choose Validation Methods and check Background Noise. Be sure to leave 5 seconds blank at the end of your recording.
Please make a new test recording and post it in a reply to this message. I will come back and review it for you.
