As a practical matter, CoreAudio supports multichannel transport of 24 bit audio via floating point streams at virtually any sample rate. If you are not careful, you can check your mail and have the “Mail recieved” sound printed into the bounce that you are doing in the background.ĬoreAudio supports a wide variety of audio transport standards. In particular, it is very easy to set up the system such that sounds from programs like email clients and other productivity tools will be mixed into your main audio stream (this happens when you set up the default audio output path so that you can use iTunes with the Mobile I/O). While this mutlticlient operation is a very cool feature of CoreAudio, and can be very helpful for many operations, you must be careful about unintended interactions. When multiple hosts send audio to the hardware at the same time, CoreAudio will automatically mix the audio before it is sent to the Mobile I/O. Mulitple hosts can recieve the audio from a Mobile I/O at the same time, and multiple hosts can send audio to the Mobile I/O at the same time.

Once the driver has been installed, CoreAudio will automatically find Mobile I/O units as they are attached to the computer and will publish the availablity of the hardware to all interested CoreAudio hosts.ĬoreAudio is inherently a multiclient interface - more than one CoreAudio host can communicate with the hardware at the same time.

The CoreAudio driver provides the required information for CoreAudio to discover and control Mobile I/O.

#MAC CORE AUDIO LATENCY INSTALL#

Since this folder is managed by the system, you will have to have administrator access on the computer to install the driver. This bundle is installed in the /System/Library/Extensions folder.

The KEXT is provided in a Mac OS X bundle called “MobileIODriver.kext”. The Mobile I/O driver is implemented as a KEXT due to the requirements of CoreAudio. This extension enhances the Mac OS operating system to provide support for communicating with the Mobile I/O hardware. The Mobile I/O CoreAudio driver is provided by Mac OS X KEXT.

Please send bug reports to support at with the subject MIOBUG Report.ĬoreAudio Basics How The CoreAudio Driver Works If you do, please file a bug report with both Metric Halo and the developer of the CoreAudio host. Even if you are using a host that is not specifically discussed here, you are unlikely to encounter problems. Metric Halo has done extensive testing with the major CoreAudio hosts, and some of the minor ones, and has worked to ensure maximum compatibility with all hosts. CoreAudio puts many more requirements on hosts than it does on drivers, so it is very likely that any such problems are in the host. If you encounter any problems with specific hosts, please let us know about it – but also please let the host vendor know about it. Most of these hosts have been fixed or are in the process of being fixed now. There are some hosts that were implemented early that did not get support for multichannel/multistream devices implemented correctly. The CoreAudio standard is quite rich and provides a number of places where host applications may or may not properly support the specification.

#MAC CORE AUDIO LATENCY DRIVERS#

Applications (programs) that communicate with hardware via CoreAudio drivers are called CoreAudio Hosts. As such, it was the natural standard for Metric Halo to support for interfacing with Mobile I/O. It provides the mechanism for making high-resolution, multi-channel, low-latency connections between audio hardware and audio applications on Mac OS X.Īll Mac OS X computer applications provide support for communicating with audio hardware via CoreAudio. Apple defined the standard and made it the primary interface for audio in OS X. CoreAudio is Apple® Computer’s technology standard for interfacing applications to multichannel audio hardware with professional quality.
