I think (and correct me if I'm wrong) that your thought was that life is too short to put a lot of blood, sweat and tears into doing any more with this 70mm soundtrack recording that is already inherently flawed. Which I would agree with for your part.
However, there are a good number of incredibly talented people here with time on their hands and the willingness to work who would be more than happy to take your raw recordings and mold them into something amazing, not costing you another penny or moment of your time in the process.
No joke... give these guys a toothpick and they'll build you a mansion! Give it a shot and I'm certain you won't be disappointed.
