4) The best option is, of course, to purchase a good quality Digital Audio Interface, such as the Peavey Xport

™

Look for a device with ASIO (audio stream input/output) drivers, which is an industry standard and will work

well with ReValver

™

MKIII.V. After you install the device, the Audio Devices menu under the File menu will allow

you to choose that device for input and output, then the Control Panel button will be activated, and serve as a

link to your device. Since there are so many available options on the market, it is impossible for us to comment

on the specics of a particular product. Just keep in mind that most ASIO-driven audio interfaces operate in a

similar fashion, and the control panel will enable you to make changes to the buer size, changing the length

of time the computer has to make calculations, and resulting in more or less latency. Generally, the smaller the

buer size, the lower the latency. However, you will have to experiment with buer sizes to nd the optimum

settings for your computer, based on your processor speed and amount of memory.

A word about latency

Latency is a technical term that basically means the time lapse between playing a note and hearing it. When

using ReValver as a stand alone program, you need to set the latency to as low a number as your computer will

allow. If you are using your PC or Mac’s original factory sound card, you are almost guaranteed to have latency

issues. It really does make sense to get a high-quality sound card, and there are many models available at

various price levels.

ReValver by itself does not control how much latency you will experience with the program, neither the

stand-alone nor the plug-in. (In plug-in mode, the latency is controlled entirely by the DAW). To control the

latency in stand-alone mode, you are advised to set the appropriate numbers in the sound card driver.

ReValver provides a shortcut to the ASIO control panel of your card. (In the “Audio Devices” menu, select ASIO,

your sound card, then press Control Panel).

The latency is directly proportional to the “sample chunk size.” Short latency equals small chunk size.

Recommended chunk size is 128-256 samples. If the sound is breaking up (choppy sound, stuttering),

increase the buer size. (Try these standard values: 64, 128, 256, 512, 1024, 2048). It is advisable to start with a

smaller number and gradually increase until the sound is no longer choppy.
