Hi - I'm a Samplitude Producer user. It's all in the algorithems. I used to think that it was all in the converters, and that once it was ones and zeroes, the software didn't change the sound. That's true only when recording, and then playing back, unaltered, a single audio file. But as soon as you start mixing, you start using algorithems, and the accuracy of the math is very important. As you start using effects, crossfades, EQ, etc, the math gets more intense. It's not just the accuracy issue either......an algorithem for an eq is a mathematical description of an analog circuit, but what analog circuit? Does it model a Neve quality eq, or a behringer quality one.
Another issue is code efficiency. If one program is written all in C+, and another gets into
native machine language, the machine language is going to be much faster. The end result is that Samplitude is very efficient code as well as very accurate. I used to get 20 tracks on a Celeron 400 with Samplitude. Now I'm running a P-3 700, OC'd to about 800Mhz, and I can get 40 tracks, all with compression and EQ, and a couple of reverbs, and still have over 40% of my CPU's MIPS available.
Samplitude is an awesome program, and I've seen a couple of naysayers become dedicated Samplitude users after doing critical A/B tests with the software they used to use. It's a little expensive, but it's a complete studio solution, and the only recording software that convinced me to give up my MDM's and digital mixer.
