how do spark and sound studio compare to wavelab and other pc based apps?
I dont know how they compare, but Sound Studio is awesome. Real simple to use and very stable with OSX. I have Spark, but I dont really like it. Ive found it to crash a lot and too damn complicated. Also, I only do 16 bit, no 24 bit so YMMV.
Just make the switch and dont look back. Macs are awesome and keep getting cooler.
