Hi,
We have an application that runs on Tiger & Panther (10.3.9).
It is compiled:
SDKROOT = /Developer/SDKs/MacOSX10.4u.sdk
MACOSX_DEPLOYMENT_TARGET = 10.3
It seems to work well in both environments but for one thing -
writing a file. We use the CAAudioFile wrapper. This is a pure
export - that is, we are not playing while writing. On a 500 MHz Ti
Powerbook running Tiger, export is fine. However, on a 2 GHz dual G5
running Panther the export doesn't work - we get drop outs, buzzing,
etc. Audio playback within the application is fine on all hardware/
OS combinations that we have tested. And, other than pulling for the
audio buffers ourselves (rather than the default output AU) and
calling CAAudioFile::Write() there are no differences between the
export and playback code.
Is Tiger really this much better?
Are we missing something?
