I was playing around with 96 Khz, 24 bit sound and noticed fairly
quickly that most apps, including Quicktime, do not support beyond 48
Khz, 16 bit sound. The apps that did support playback of high res
audio didn't. When I was using Peak 3.0, I noticed I was able to
playback sound when using CoreAudio setting but not when using either
of the HAL settings. The HAL (CoreAudio Framework) interfaces with the
Audio Family in the kernel yet its possible to bypass the HAL itself
and access CoreAudio. Also, its noted that CoreAudio supports 96
Khz/24 bit sound as current yet the M-Audio Revolution drivers sport
192 Khz and the checkbox to boot. Also does Quicktime rely on the HAL
system? Lastly, any shareware/freeware apps that I can recommend to
readers that can playback 96 Khz/24 bit sound? Thanks in advance for
to any replies!
Any software (which includes Quicktime) that is based on the Carbon
Sound manager has a playback limitation of about 65KHz. CoreAudio
suffers from no such limitation. I don't know of any software (outside
of professional level software) that users can use, but a search
through versiontracker may prove enlightening.
