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. Most of the latency caused by bad sound devices is
caused by slow lazy sound drivers. |
| |
| 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
|
1200 samples |
| |
| Sound device |
Abit VA-20 motherboard with onboard Realtek AC97 Audio |
| Sampling Frequency |
48,000 Hz |
| Buffer Size |
1200 samples |
| |
| 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. |
