xWave overview
xWave generates the signals needed for audio amplifier and speaker testing. The interface is intuitive and provides all of the necessary controls without excessive screen clutter.
Features
- All of the standard waveforms are present - sine, square, triangle, and sawtooth. Frequency range is 1 HZ - 22050 Hz.
- The square wave has a choice of 20 us or 40 us rise time. The slow setting reduces the ringing inherent in a digital filter, while the fast setting provides the maximum harmonic content.
- The Sweep function provides a continuous frequency sweep containing signals in a selected audio range.
- The Burst function outputs from 1 to 20 waves in a repeated sequence.
- The left channel can be switched to a sync signal, necessary for triggering on sweep and burst modes.
- The right channel phase can be adjusted from 0 - 180 degrees with respect to the left channel or sync.
- An important feaure is the Calibration mode, which allows the user to adjust the displayed output voltage to the actual measured output.
- All settings are saved between runs.
- xWave has been designed to be versatile yet easy to use.
What’s new in version 3.1
Updated on Jul 17 2019
Version 3.1:
- The Spectrum function is an exciting addition to the xWave waveform suite. More flexible than the usual noise generator, it enables generation of random noise restricted a user-defined frequency band. For instance, if you want noise only between 1000 Hz and 2000 Hz, xWave can do it ! In addition, there have been a few tweaks to the user interface, including a selectable darker background.

Version: 3.1
If you have a recent vintage receiver or amp and your speakers are not regularly connected to your computer, I suggest checking its manual as may newer audio components already have this function built-in. Some even include a calibration device. If your speakers are attached to your computer free audio test sites exist on the web. Just do a browser search for "Audio Test Websites". The first site that I found but not used is "https://www.audiocheck.net/" . There are literally dozens more.
For those that feel I am unfairly targeting a developer, I feel that such developers are exploiting uninformed users for a source of income. I would encourage them to instead focus their development on applications for which their might be a real need, ethically creating an income stream for themselves.
