Apollo Solo USB Manual Console Settings 156
Buffer Size
This setting determines the hardware I/O buffer size used by a DAW. As values are
decreased, DAW throughput latency decreases, but the computer’s CPU load increases.
Conversely, as I/O buffer size values are increased, DAW throughput latency increases,
and the computer’s CPU load is reduced. For related information, see Latency Basics.
Available buffer size values are dependent on the current Sample Rate value. If values in
the Buffer Size menu are gray and cannot be selected, change the Sample Rate value.
Note: If audio artifacts occur during DAW playback (clicks, pops, stuttering, etc),
the buffer size may need to be increased.
Important: Buffer Size only applies when using ASIO and/or WDM audio with
a DAW or other audio applications. It has no effect on Console’s hardware
monitoring features or Realtime UAD Processing within Console.
USB Safeguard
If audio artifacts occur during audio playback (clicks, pops, stuttering, etc), USB
Safeguard may need to be set to ON. Enabling USB Safeguard increases DAW latency
slightly, but it can help optimize audio playback when the host computer’s CPU is taxed
with high loads (for example, when running high track counts on slower systems).
Note: Stop WDM and ASIO playback before changing the USB Safeguard setting.
Applications using audio may need to be relaunched if the setting is changed.
Important: USB Safeguard only applies when using ASIO and/or WDM audio
with a DAW or other audio applications. It has no effect on Console’s hardware
monitoring features or Realtime UAD Processing within Console.
