WORKING WITH HOST AUDIO SOFTWARE

playback is extremely precise, it is only the

monitoring of your live input signal which may be

delayed.

Adjusting your host software audio buffer

Buffers are small bundles of audio data. The

Stage-B16 “speaks” to your computer in buffers,

rather than one sample at a time. The size of these

buffers determine how much delay you hear when

monitoring live inputs through your audio

software: larger buffers produce more delay;

smaller buffers produce less.

Adjusting buffer size on Mac OS X

Under Mac OS X, audio I/O buffer size is handled

by the host audio application (not by the

Stage-B16’s Core Audio driver). Most audio

software applications provide an adjustable audio

buffer setting that lets you control the amount of

delay you’ll hear when monitoring live inputs or

processing them with software plug-ins. Here are a

few examples.

Figure 6-4: In Digital Performer and AudioDesk, choose Setup menu>

Conﬁgure Audio System> Conﬁgure Hardware Driver to open the

dialog shown above and access the Buffer Size setting. Refer to your

Digital Performer or AudioDesk manual for information about the

Host Buffer Multiplier setting.

Figure 6-5: In Cubase or Nuendo, choose Devices menu > Device

Setup. Select your interface (Stage-B16), then click the Control Panel

button to access the window above and the Buffer Size setting.

Figure 6-6: In Logic Pro, go to the Audio Driver preferences to access

the Buffer Size option shown above.

Adjusting buffer size on Windows

To adjust buffer size on Windows, visit the MOTU

AVB USB Control Panel. See “MOTU AVB USB

Control Panel” on page 28.

Lower latency versus higher CPU overhead

Buffer size has a large impact on the following:

■ Monitoring latency

■ The load on your computer’s CPU
