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.
