Hello,
To keep it simple, it can be done, and i think i can do it in less then 1-2 hours, depending on the length of the audio, and how much i must do manually.
But it shouldn't be a problem. Message me as soon as you can if you want me to start right away.
I have experience in audio production, but for this problem that isn't really important, so i won't bother you with that.
Also if you have any questions, feel free to ask me in messages.
Kind Regards,
Nyro
