Does your computer have a PCI slot. I like the M-Audio PCI interfaces so much I'm trying to buy one. Really haven't used one yet but I've heard all good about them and they are used for about $100.
The OP specified a MacBook, which is a laptop, so no, it is safe to say that it doesn't have PCI.
That said, although M-Audio's PCI cards were great for their time, they aren't particularly good these days. The difference in sound quality between my old 1010LT and any of my FireWire interfaces was like night and day. The sound from the newer interfaces is dramatically clearer, cleaner, more accurate, less noisy, etc. It's like a fog has been lifted when you hear the difference. That's the only way I can describe it....
The Delta boards were groundbreaking in that they were among the first prosumer cards designed for recording. They came out at a price point under a grand in the late 1990s when the hardware involved would normally be many thousands of dollars.
Since then, economies of scale have drastically driven down the cost of quality components to such a degree that even the cheapest FireWire interfaces today produce recordings that sound far clearer than even M-Audio's most expensive PCI interface, the Delta 1010 (which has a long history of capacitor failures, just to add insult to injury).
Save yourself a lot of headaches and a lot of poor quality recordings and skip directly to a more modern interface with more modern converters. Technology has come a long way in a decade, and the M-Audio PCI hardware is basically a decade-old design at this point.
