Hello, I would like to edit 3 audio recordings (spoken word) about 2 minutes long. It’s about reducing the amount and other things in the background. Someone would be willing to make this small adjustment. I tried it myself, but it’s not the meeting. Thanks in advance for the answers.
I am not sure exactly what you are asking about. Perhaps you are looking for the noise reduction effect. See here: Noise Reduction - Audacity Manual
I hope this helps. 
Hello, I tried this, but it’s not enough 
I need someone who has experience
May I suggest you post a 10 second clip of your .WAV file here. Perhaps someone “who has experience” will look at it and comment. See here: https://forum.audacityteam.org/t/how-to-post-an-audio-sample/29851/1
