Adjusting the Play Buffer Size for Audio
(Software-only Models)
You can use third-party host audio devices, such as a Sound Blaster
®
audio card, in software-only
configurations of Avid editing applications. Although most host audio devices work properly
within Avid editing applications, some exhibit problems during output (for example, audio
clicking). You might also encounter audio latency issues when adding audio effects such as
volume automation. To counteract these problems, use the Play Buffer Size in Samples slider and
the Tool Buffer Size in Samples slider in the Audio Settings window.
Avid strongly recommends that you use the default “recommended sample” setting, which is
determined by the host audio device connected to your system.
For more information on the Buffer Size in Samples sliders, see “Audio Settings” on page 1290.
To adjust the samples in the play buffer or tools buffer:
1. Double-click Audio in the Settings tab of the Project window.
The Audio Settings window opens.
2. In the Play Buffer Size in Samples, click and drag the slider to select a sample size.
3. In the Tool Buffer Size in Samples, click and drag the slider to select a sample size.
If you change the default setting, a warning dialog box opens informing you of how this
change might affect your system.
4. Click Change.
5. To select the Avid recommended default setting, click the rs (recommended sample) button.
