AudioAnalyzer Frequently Asked Questions

AudioAnalyzer is a Java-based software-only program that lets your PC generate audio signals and observe their time and frequency characteristics. AudioAnalyzer lets you create a variety of audio waveforms that can be output to the computer's HEADPHONE / LINE OUT connector. You can also use the two channel oscilloscope to monitor those waveforms or select signals from the computer's audio system mixer. The Spectrum Analyzer gives you a Fast Fourier Transform (FFT) view of the waveforms.

2. Does it replace expensive test equipment?

No. Performance may be limited to audio frequencies (typically 20 to 20,000 Hz) supported by the PC's audio system hardware and drivers.

3. Why do I want to use beta software?

It works and pricing reflects beta status. Beta software does not have user feedback incorporated yet, so you can help improve its usability and operation with your feedback. Check out the Tutorials on our web site for things you can do now. With a subscription you can download the latest version every time you log in. Check the bug reports for tool limitations and status.

4. What's the biggest issue with the tool?

Only one of the data capture modes is currently available. This mode has a selectable rate up to ~ 1 second which may not be fast enough for some applications. See the bug reports for capture mode status.

5. Is the tool intended for newbies?

No. We assume you have some knowledge of working at audio frequencies and recognize when and where to apply the right tool for the right job. If the Tutorials and User Manual aren't obvious and if the "Things You Can Do" list doesn't match the things you do, the tool is not for you.

6. Can I run the tool when not connected to the Internet?

Yes, The Java Web Start deployment scheme caches the last version on your computer so you don't have to be connected.

7. Why is calibration needed?

Calibration is only needed if the accuracy of the Oscilloscope voltage readings are important to you. Calibration compensates for variances in computer hardware and various software "volume control" settings found in a typical computer. Calibration can be easily performed with the eightolives' Protection Calibration Unit (EPCU). You can also perform calibration manually for which you must make a few measurements on the LINE OUT signals using an external AC voltmeter or oscilloscope.
