WWDC Preview: Apple to Improve USB, FireWire Audio Support in 10.5

In a little while, Steve Jobs will be keynoting Apple’s developer conference. I doubt that anyone will be thinking about audio drivers. So in the remaining moments to do that, let’s go — because 10.5 looks like it’s yet another release from Apple that takes music production seriously.
Most of us didn’t expect any major improvements in Apple’s Core Audio in 10.5 — nor need them, as Core Audio is rock-solid for most of what we need to do, in terms of performance and reliability. That’s not to give Apple a free pass; there have been some compatibility issues with point releases (10.4.9 comes to mind), bumps in the AU plug-in format’s evolution, and so on. But at the end of the day, the Mac is an OS that works for music production, more seamlessly and easily than anything else out there. Yet Apple is in fact making some improvements to its audio driver system even in 10.5:
164 Professional Audio Input and Output with Leopard Mac OS X Essentials Presentation
Discover Leopard’s support for the recently-approved USB Audio Device 2.0 class specification and how to write spec-compliant descriptors for your high-speed USB audio device. Find out how to unleash the power of FireWire peer-to-peer networking using Leopard’s all-new FireWire audio drivers and enhanced Audio/Video Control (AV/C) media services. Learn how to implement user interfaces and vendor-specific AV/C commands to control your audio device.
So, wow, in other words … in a release that’s largely focused on Core Animation and the visual side of the operating system, Apple has added new FireWire support, networking over FireWire, and driver-free USB 2.0 support. (Right now, you can plug-and-play class-compliant USB 1.1 audio devices, but not USB 2.0. Erm … or whatever those two USB specs are really supposed to be called; that’s another discussion.)
