Hi!
I understand how frustrating this probably is for you. But luckily, there is hope!
I am a professional audio engineer working both in live, studio and post production. I have all the necessary software and tools to get the job done for you in a timely manner. I will be working in Reaper, a professional digital audio workstation (DAW). Not only can I separate the two vocals for you, but I can also do some audio restoration and processing to help boost the overall sound quality.
There is one thing you must know, though - If there is ever a part in which the two people are speaking over each other, then they cannot be separated. This is not a limitation specific to me; it will be the same with anyone.
Here is what I can provide you with:
3 tracks of high quality audio -
Track 1: Person 1
Track 2: Person 2
Track 3: Person 1 and 2 talking over each other
I am excited to get this done and look forward to hearing from you soon!
Cheers!
