This will be much easier from python than using the DOS box as
an intermediate. I use Audacity but have no idea whether it
has any kind of message interface, but at the worst case you
can generate windows message events and use the Win32 API
to send them (using PostMessage() API call) to the Audacity
window.

But since Audacity is quite a sophisticated programme I
wouldn't be surprised if it has a message based API of
its own.

If you have to use the WIin32 api then its faurly messy
and will require some experimenting from the >>> prompt
to work out exactly what you need to do. BUt its not impossibly
difficult.

If Audacity exposes an interface of its own then it shouldn't
be too hard at all, you'll need to check the Audacity docs
and web site closely.
