That something would be more like this (but it has only limited value, see 
below):

#!/bin/bash
/usr/bin/audacity &
pid=`jobs -p 1`
sudo renice -5 $pid

But there are (at least) 3 problems here:

First, you can renice your own processes to get a lower priority (higher 
nice value), but only root may rise the priority to negative nice values. 
That's why we need sudo here.

Second, only users in the admin group can use this trick to improve the 
priority.

Third, you will only see the password prompt on the terminal if audacity 
doesn't hide the terminal. And you have to start the script from a 
terminal to get the password prompt at all.
