Hello,
I am a sound recordist, editor, designer and music producer. I am specialized in podcast post-production, audio fixing and optimization. I have carefully read your job post description and heard the YouTube video. Yes, the audio is very poorly recorded and it is hard to understand the words. Here is what we can do: we can lower the echo of the room, we can equalize the women's voice so that it sounds less like from a telephone, and we can remove unwanted sounds.
Feel free to ask me anything you like.
If i get your reply, i am willing to do a part of the YouTube video so that you know how it would sound.
Regards,
Pavle
