Audio Mastering for 50-Minute Theatrical Show Track

I’ve created a 50-minute continuous audio track for a theatrical cabaret-style show, using GarageBand. It’s a combination of edited backing tracks — some with added instruments, light backing vocals, and spliced transitions. The final file is one complete mix, and I’m now looking to have it professionally mastered to ensure it sounds polished, balanced, and clear over a theatre PA system.

About the Project:

The show will be performed in a 300-seat venue aboard a cruise ship, so clarity, dynamic control, and consistency are essential.
This is not a stem mix project
I’m looking for a mastering pass to elevate the track for live playback.
What I Need:

EQ balancing
Compression and dynamic control
Volume leveling across the track
Stereo enhancement
A clean, professional finish suitable for live theatre playback (not for streaming or commercial release)
What I’ll Provide:

One complete 24-bit WAV file
Reference tracks or additional notes if needed
If you’re experienced in mastering theatrical or live performance tracks and can ensure clarity and warmth across a long-format file, I’d love to hear from you!

Looking forward to your proposals!
