Hello,

Here is the sample with 12 dB of noise reduction and notch filter at 100Hz. I also applied notch filter at 120Hz after looking at the noise spectrum.

I hope notch filter is the same thing as the rumble filter you requested. The description sounded similar, but I was not sure if it was what you requested. Thank you.
Hello,

No, a notch filter pulls out specific frequencies. You need to exclude all frequencies below about 100 Hz. You can do this using
Filter Curve / Equalizer, and applying a filter that removes these frequencies. It's probably better to show you. A
Do you want to have a quick Zoom session with me? I'm in the UK timezone.

Best Regards,
Adrian
Thank you so much for the offer, but I would not be able to do that. Could you point me to a video, or tell me around which points you have the filter curve set at? I'm very sorry for the inconvenience.

Hello Zoe,

Congratulations - you meet librivox's technical standards. Proof Listen OK!
-----------------------
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. I recommend starting with short works, such as poetry and dramatic readings.

Thank you again for participating in Librivox,
Adrian Stephens
