Audio Latency
To use a live music program you'll need fast sound hardware, with good
low latency drivers. Latency refers to the time delay between a sound
being sampled and the sound coming out of your speakers. |
| |
| Here's some example sampler settings
that work well: |
| Sound device |
Sound Blaster Audigy SE / Sound Blaster Live 24bit |
| Sampling Frequency |
48,000 Hz |
| Buffer Size
|
512 samples |
| |
| Sound device |
Realtek AC97 Audio |
| Sampling Frequency |
48,000 Hz |
| Buffer Size |
1200 samples |
| |
|
| Sound device |
Realtek HD Audio |
| Sampling Frequency |
48,000 Hz |
| Buffer Size |
512 samples |
| |
| Sound device |
Behringer Guitar Link
UC6102 |
| Sampling Frequency |
48,000 Hz |
| Buffer Size |
256 samples |
| |
| Buffer sizes
also depend on cpu and memory speed. Slower systems will need to use
bigger buffer sizes. |
| |
| If you are experiencing choppy or
delayed sound try some of the following things: |
1. Reduce the sampling speed, this will
reduce the sound quality a little, but reduce choppy sound.
2. Increase the sampling buffer size to reduce choppy sound, this
however will increase latency.
3. Note that when CPU usage exceeds 50% choppiness and latency may
increase a lot.
4. If latency increases and becomes too high turn off the sampler by
pressing the power button,
wait 2 seconds then turn the sampler back on, this will get rid off
any latency increase that
has occurred over time. |
| 5. Turn off your screensaver. 3d
screensavers can sometimes consume a large amount of cpu time even if
they are not running. |
| 6. Turn off all non essential programs and
services while using any recording program, especially instant
messengers, anti virus, anti spyware, and any network programs, as
these may cause audio drop outs, or extra latency. |
