But the real advantage would be if you could test Soundcheck in real time. As you were working you could see, for example, that your mastering was giving you 6 db of gain reduction/makeup gain, but Soundcheck was dropping the whole thing by about 6 db...so no good. Then you could adjust things in real time until maybe you found a setting where you were getting 3 db of reduction/makeup gain and Soundcheck was dropping the whole thing by 1.5 db. Then you would know you were getting somewhere.
If it was real time, you could find the exact line where you start pissing in the wind and then not cross it, possibly saving countless songs.
