How low latency can you get on a MAC?

So got my first MAC and I am wondering how latency works on MAC.. on PC you need to have ASIO driver.. am I correct that on a MAC no drivers are used, even with pro cards, so that Core Audio does it all?
Important, where you can set things like buffer size, samplerate and how low latency (ms) does a MAC give you when working 44.1khz etc..
Thanks for the help! |

at 48 k , i get round trip 3.2 ms. I use a buffer of 64. I do have an apogee symphony which is pretty much as quick as it gets. A tad slower than a protools rig.
I'm pretty sure MAC has higher latency across the board. not significant but still,
I used to have an rme UC, could get at 44k 6 ms round trip. |

I use Apogee Duet with buffer set to 128. Fast enough...
This can let me know when a Logic bug (Logic is full of bugs) prevent the latency compesation! If I have 64 I'll not be sure if Latency Compensation is on or off (bugged)...

I also get about 3.2 ms running traktor on my macbook pro using the S4's soundcard.
I can get it even lower since traktor isn't that CPU intensive but figured i'm already running at 96 khz, and I can't really tell the difference below 5 ms so it's good enough for me. |

traktor doesn't really count. I mean you can get away with such a low buffer.
Most sound cards will run well at 512, 44k and that will get you about 20 ms one way
People saying they have 3.2 round trip running a ty sound interface are lying or they are distorting the actual setup. You will not be running DAW with reasonable stress at 3.2 ms with a dj interface. |

Some additional questions:
1- do you really need an extra soundcard (USB?) with a MAC to get low latency.. how low latency does the build-in soundcard of the iMAC (or Macbook Pro) give you? I thought MAC had low latency out of the box.
2- do you setup latency (buffer) in the setting of each program like Logic or are there system settings related to this in the MAC OS X?
3- how much milleseconds do people consider good latency for playing softsynths etc.. without audible delay?
4- to get low latency, isn't it best to stay at 44khz if you only use softsynths (so no recording)?
Thanks! :) |

| depends on number of channels, instruments, fx, ram, cpu, and other things. things will be better performance wise with a dedicated sound card but the internal is alot better than PC-soundcards imo. the question is really why you need such ultra low latency? do you record yourself play piano or sing realtime? back to your second question i believe you set it up in logic, i dont have logic installed right now as im changing hard drives and installing the new OS etc but im pretty sure it was done in Logic (or whatever daw your using, like Reason). |
