5. Audio Applications

This chapter contains basic configuration examples for some popular software applications. Please

also refer to the manual of the audio software you use for detailed information.

The Windows Multimedia setup is required if you want to use your ESU22 as the main sound

device for Windows multimedia applications. Go to My Computer-> Control Panel -> Sounds and

Audio Device Properties -> Audio. Select the ESU22 entry as your playback device to make sure

that all standard signals are played via the ESU22 hardware.

Via Config > Latency in the Control Panel it is possible to change the latency setting (also called

"buffer size") for the ASIO driver of ESU22. A smaller latency is the result of a smaller buffer size.

Depending on the typical application (e.g. for playback of software synthesizers) a smaller latency

is an advantage. At the same time, the best latency setting indirectly depends on the performance of

your system. For recording applications, a typical latency buffer size between 128 and 288 samples

is standard. The default value is 256.

The Config > Buffer Number setting in the Control Panel provides an important fine tuning setting

that allows you to tweak system performance. Depending on your computer hardware, you might

need to adjust this setting if you have problems with noise or drop-outs during playback or

recording . Typically on a modern computer system a value of 4 or slightly more or less is perfect

but you might need to check what is best for your computer as every PC is different.

Note that these values have to be setup before launching any audio application using ESU22.

The main control center of ESU22 under Mac OS X is the Audio MIDI Setup application that you

can find in your Applications folder. When you launch it, you can setup ESU22 as your Default

Input, Default Output or System Output device – if required.
