Performance
Mac OS X delivers the best audio performance in desktop computing. The most funda-
mental measure of audio performance is throughput latency. That’s the time it takes for
audio to enter your Mac, travel through the system to your application and then pass back
out to your monitoring system (speakers).Historically, Mac OS offered excellent latency of
about 10ms. The Core Audio HAL (Hardware Abstraction Layer) provides ultra low latency
of only 1m — and you get this performance in a full multi-channel environment.
Stereophonic Multi-Channel
Previously you had to install third-party system extensions to work with more than a
2-channel stereo mix.Now with Mac OS X offering native support for multiple channels,
you can simultaneously record with more than two microphones,and perform large-scale
professional tape transfer in a single pass, with greatly improved performance. The Core
Audio HAL also allows multiple applications to share the same device.This means that you
could assign channels 1-6 of a eight channel output device to a multi-track program, such
as Logic, while leaving a virtual instrument like Reason with channels seven and eight.
High Fidelity
Core Audio manages all audio as 32-bit floating-point data. This allows your Mac to
efficiently handle 24-bit/96 kHz audio as well as higher resolutions. Core Audio also
delivers highly optimized sample rate converters to allow programs that do not yet use this
high-resolution format to provide data to Mac OS X without truncation.
Audio MIDI Setup
Mac OS X has an easy to use setup application called Audio MIDI Setup.This
provides applications with the ability to manage MIDI and define a system-wide MIDI
configuration that is available to all of your applications.In addition, Mac OS X provides
applications with Music Services, which are the fundamental functions of MIDI sequencers
including cut, copy, paste, repeat and other common MIDI editing routines.
Reverb-erb-erb
In the absence of a system level plug-in architecture,third party developers created a vast
array of DSP effects which are mutually incompatible.Core Audio enables developers to
offer audio plug-ins in a more centralized manner,called Audio Units,making it simple to
manage the audio capabilities you add to your setup.Apple includes several Audio Units in
Mac OS X, including a Velocity Engine-optimized reverb and a sample rate converter.
Plug and Play
Mac OS X includes USB class drivers for connecting audio and MIDI devices to your Mac,
and will automatically recognize those devices that comply with industry-standard
specifications when you plug them in.You don’t have to install extra software to use them.
64-bit Performance
The PowerPC architecture was designed from
the beginning to run both 32-bit and 64-bit
application code, offering seamless transition
to 64-bit performance. Current 32-bit code
— such as Mac OS X,the Mac OS 9 Classic
environment and existing applications —
runs natively at processor speed. With no
interruptions to your workflow.And no
additional investment in software required.
Graphics and Display Support
◆ Compared with the AGP 4X interface, the
Power Mac G5’s AGP 8X Pro graphics bus
effectively doubles the maximum transfer
rate and doubles the amount of data trans-
ferred in a single AGP bus cycle. The
66MHz AGP 8X Pro bus strobes eight
times per clock cycle,achieving a 533MHz
data rate and a maximum bandwidth of
2.1GB per second — ideal for the ultrafast
ATI Radeon 9800 Pro or NVIDIA GeForce
FX 5200 Ultra graphics cards they include.
◆ Supports 1920 x 1200 pixel digital resolu-
tions and 1600 x 1200 analog resolutions
◆ ADC and DVI connectors; DVI to VGA
adapter included
◆ Dual display support for extended desktop
and video mirroring modes
◆ Support for two Apple flat panel displays
Storage and Expansion
◆ Two Serial ATA controllers supporting up to
150-MBps data throughput per hard drive
◆ Tw o 3.5-inch hard drive expansion bays
with drive guides for a second drive
– One 80GB or 160GB 7200-rpm Serial ATA
drive installed in standard configurations
– Support for up to two internal Serial ATA
drives; 500GB maximum system capacity
–8MB memory buffers on all hard drives
◆ Optical drive bay with SuperDrive (DVD-
R/CD-RW) installed; writes DVD-R discs
at up to 4x, reads DVDs at up to 8x,writes
CD-R discs at up to 16x and CD-RW discs
at up to 10x, reads CDs at up to 32x speed
◆ One of the following PCI expansion con-
figurations: Three open full-length 64-bit,
33MHz PCI slots, or one open full-length
64-bit, 133MHz PCI-X slot and two open
full-length 64-bit 100MHz PCI-X slots.
Mac OS X Core Audio
Musicians, audio pros and music educators have long recognized the Mac as the superior
platform for creativity. Historically, third party developers augmented the native capabilities
of Macintosh with a wide variety of hardware, software and system add-ons, making it
possible to use the Mac as a virtual recording studio. However, configuring such a studio
became quite complex, and didn’t allow for the highest level performance possible. With
Mac OS X, professional-level audio is here. Mac OS X Core Audio integrates audio functions
directly into the operating system in ways never before possible, enabling unprecedented
performance and ease of use in your virtual studio. Core Audio lays a new foundation for
the next generation of world-class audio and music applications from innovative developers.
