I only need it for this one task, to see if I can get a little more speed out of sound on Q3.Ĭan you recommend a good PCI card for this that will do 11khz with this driver?Ĭlick to expand.Consider also that pci cards are way easier on the cpu than external cards due to the fact that they can use dma directly, so unlike usb devices for which the cpu has to constantly send packets over the bus.įor the audio drivers the system architecture in OS X is also way better than in windows, but it's made for DAC and ADC kind of devices, to support more advanced features of an hardware one should make a completely custom software stack (including api). I used this code before with an Intel Hackintosh and an Audigy 2 Gold PCI, so I'm somewhat familiar with the limitations in audio in. I did try my Firewire M-Audio box, but that really takes a hit with sound enabled, so device and drivers do matter.
My QS only does 44khz so I can't test to see if a can squeeze a few more FPS out of it by lowing the sample rate. I have a G5 that can do 33khz and it's quicker at that speed than 44khz or 48khz in FPS with sound enabled. I think on the Mac the CPU is doing all the upsampling to the fixed speed of the Mac's built-in sound. On the PC side most of the competitors have fixed the audio to 11khz for best speed gain. There is a Quake 3 competition for retro computers that must be run with sound enabled and that's a big hit in performance on the Mac without SMP as Quake3 puts the sound subsystem on another core if I could enable SMP, but it violates the rules.
So if you need an old school PCI card get either a sound blaster live or an audigy (those can also do also 24 bits, the live ones and other older ones are limited to 16 bits) and if you need a pcie card get the audigy rx.Ĭlick to expand.I have a G4 MDD on it's way to me, a long with a few QuickSilver G4's I already have. **NOTE** also that the driver is currently *BROKEN* when it comes to *INPUTS*, so i can recommend this just for playback and it's not tested for production environments.įor your needs i don't recommend getting an E-MU branded card since those can just do 44.1 and 48 khz natively (and have 192 khz support via speed+pitch change) and are not tested on powerpc. Yeah they are both supported, on each sound it supports card the driver can do from 7khz up to 192 khz at 16 bits (and can do also 24 bits on some more recent cards like the sb audigy series), just get a compatible sound card, and install the driver, however the driver works best for 48khz since that's the actual native sample rate of the hardware, support for other sample rates is achieved by changing the playback speed and the pitch inside the driver code.
