Q. is there a reason/fix for the increase in latency in lion when using the original Apogee Duet soundcard in Lion 10.7.3 through Logic Pro?
Buffer size 128 is no longer usuable - artifacts, pops, crackles (usual buffering problem symptoms), 128 was usuable with Leopard.
10.7.3 has been quite shaky all round ..........
Mobile Rig: MBP 2.33 C2D 3Gb 256Vram, Mac OS X (10.7.3), Logic Pro 9.15 (64 Bit), Automap 4 - push the machine...........
Here's the figures :
I/O buffer size = 256
Resulting Latency round trip 16ms
Click on the acutual words reading the title above in the audio/preferences pane and it changes,
Resulting Output Latency 8ms
TIP: the yellow tool tips (OS X) when hovering inform you the speaker distance conversion - pretty cool
Although very handy info,
I've gained 2ms at least from SL - just enough for a guitarist tracking, while using onboard plugins, to be distracted in close overdub sessions (unusable)
Using 44.1KHz sample rate to avoid dithering and extra process.................I know...........
I hope I've missed a setting or setup procedure, if anyone else could post their figures/advice,
it would be appreciated.
