Thank you. Your voice is good and most of your tech specs are fine but there are two things I would like you to change, make another test and put the link here. Call it test 2 or someothing like that.
1. you have too much background noise. Please run Noise Recuction on the track at about 15 db. Here is a video explaining how to do it with Audacity. If you have another program, let's talk.
2. Your DC offset is really a lot. This is easy to fix also with Audacity: Effects>Normalize>Remove DC offset. Do not check the box about automatic increasing gain.
Let me know if you have any questions.
