Remove Background Noise

Thank you so much your provided free services for poor people like us. Even in our lifetime we cannot afford your purchased services. Our monthly income is less than $100.
Now I am trying to find a way to earn money online by learning from YouTube videos.

I am trying to remove the noise of the merged 2 mp3 file.

  1. First, I merged the 2 mp3 files
  2. then uploaded the same for the noise removal

But the file has been working now for more than one hour.
Is it still working or is it an issue?

What are your suggestions? I want two m4a files converted to mp3 and merge them to create one mp3 file and remove its noise.

I appreciate your kind cooperation in this regard and thank you
Sincerely,
Sanath
