Problems editing audio book to pass acx

I am asking if there are specific settings I need to set before I start recording (for the items listed ACX requirements below)? I understand what you mean regarding the background noise. I will work on it.
-Each file must measure between -23dB and -18dB RMS.
-Each file must have peak values no higher than -3dB.
-Each file must have a noise floor no higher than -60dB RMS.
-Each file must be 192kbps or higher 44.1kHz MP3, Constant Bit Rate (CBR).


Microphone - Blue Microphone Yeti USB Microphone (Slate) with Headphones and Knox Pop Filter. It is connected directly to the laptop through USB and the headphones are connected directly to the Yeti microphone.

I will have to review the link tomorrow.

Public speaking - yes, I am a former teacher, and I have been master of ceremony, and I have given speeches.

Ok on the filenames.
