UA-20 application guide

Adjusting the audio latency

When using the UA-20 in Advanced mode, you can change the driver settings to adjust

the latency of the audio. To adjust the latency, change the Buffer Size in the driver

settings dialog box.

* Latency is the time delay from when an application plays back audio data until the sound is

actually heard from an audio device such as the UA-20.

As described in “Opening the special driver settings dialog box (p. 65)”,

open the “Driver Settings” dialog box.

Adjust the driver buffer size.

The following setting will produce the shortest latency.

Windows:

Set “Audio Buffer Size” to the far left (Min).

Macintosh:

Set “Buffer Size” to the far left (Min).

Click [OK] to close the driver settings dialog box.

Restart the application that is using the UA-20.

If you are using an application that has a function for testing audio devices, get it to

perform its tests.

Play back audio data on your application.

If interruptions occur in the sound, repeat this procedure, and gradually increase the

buffer size specified in step 2 until interruptions no longer occur.

* Depending on the application you are using, there may be a buffer size or latency

adjustment function among the audio settings of the application as well. For details, refer to

the operation manual for your application.
