howdy, list.
i've prepared a bugfix release of MTCoreAudio to address an issue
discovered by John from Griffin Technology, that manifests on Leopard
when using MTBuffer or its descendants (MTAudioBuffer,
MTByteBuffer). this release also includes other changes i've made
since the last public release. the release notes covering the
changes since the last public release (1.3.0 on April 4 2004) are
included below. you don't need to upgrade if you're not using
MTBuffer, but some of the new features may be of interest. note
specifically that the binary is universal, and the Xcode project is
set to build universal.
i'd hoped to make the Next Big Release much more interesting than
this, but i'm sad to say i haven't had the time to spend on it.
MTCoreAudio is still to be found at
http://aldebaran.armory.com/~zenomt/macosx/MTCoreAudio/
New for 1.3.2 (2007-11-04)
(class MTBuffer and descendants)
o Leopard fix for incorrect use of NSConditionLocks (now uses
POSIX locks and
condition variables -- NSCondition would have been nice but
doesn't work
correctly pre-10.5)
(sample app AudioMonitor)
o update project to Xcode
(misc)
o build universal framework and universal AudioMonitor
New for 1.3.1
(class MTCoreAudioDevice)
o notifications (such as
MTCoreAudioHardwareDeviceListDidChangeNotification) will
not be sent before the first use of class MTCoreAudioDevice
(class MTBuffer and descendants)
o new method -close
o new method -configureForSingleThreadedOperation
(sample app AudioMonitor)
o made MTConversionBuffer class better for general buffered
sample rate conversion
o new class MTVarispeedConversionBuffer. uses Varispeed and
Converter AUs
(misc)
o new utility function MTAudioBufferListSetFrameCount()
o new value transformers (between linear and decibels) for use
with Cocoa Bindings
enjoy!
