Need Help with Audio Separation

Hello Adobe Audition community!

I hope you're all doing well. I'm currently working on a project involving an old VHS video that I've digitized on my PC. The video and audio are combined into one file, and my goal is to separate the vocals from the instruments in the audio. However, I'm encountering difficulties, particularly when using the audio after editing it in Audition on Moises App.

Here's a summary of my situation:

• I have an old VHS video recorded digitally on my PC.
• The video and audio are combined into one file.

My objectives:

1. Separate the vocals from the instruments in the audio file.
2. Edit the separated audio in Adobe Audition for further enhancement.
3. Utilize the edited audio in Moises App for additional processing.

Specific issue:

After editing the audio in Adobe Audition and using it in Moises App, the output doesn't meet my expectations. The separation quality seems to degrade, and the extracted instrumental sounds less clear than anticipated.

I'm reaching out to this supportive community to seek advice, guidance, or alternative methods for audio separation in Adobe Audition. Additionally, if any of you have experience with integrating Audition-edited audio into Moises App for further processing, I would greatly appreciate your insights.

If you've successfully accomplished similar tasks or have any knowledge of plugins, settings, or workflows that could aid me in achieving a high-quality audio separation, please share your expertise.

Thank you so much for your time and assistance. I'm eager to learn from your experiences and overcome this obstacle to create an impressive audio track from this old video.

Best regards, MarsEverythingTech
