Getting Started

AudioAnalyzer Screen ShotTo run AudioAnalyzer you purchase either an AudioAnalyzer Kit, an on-line download subscription for one year or an AudioAnalyzer CD from our on-line store. A subscription lets you download, use the tool, and get updates for 1 year. After that period, you retain and can continue to use the last version you downloaded. The Kit contains the tool on CD, calibration cable, test cable, documentation and support files and includes a one year subscription for updates.

AudioAnalyzer is a program that requires Java to be installed on your computer. See the Install Page for detailed computer requirements on that and other optional third-party software you may wish to pre-install.

When you buy AudioAnalyzer, you will be emailed your initial login password. Subscribers can change their password at any time. At the AudioAnalyzer Login page enter your email address, which is your user name, and your password to start the software.

If you need help in getting started, you can either email our Help Desk at help@eightolives.com or call us at 1-978-682-6535 (8am-5pm ET).
