Advanced ABX, New cross-platform ABX application Options

Advanced ABX

No currently available ABX application is able to switch without audible transients between tracks. The resulting clicks and pops can both increase the number of false positive and false negative results. The former happens, when the type of clicking correlates to the type of switch: A/A or A/B. False negatives become more probable, when loud clicks desensitize your hearing or keep you from turning up the volume to more revealing listening levels.

Advanced ABX provides transient-free switching!


Other exclusive features:

• Impedes "fishing" for good results by design by enforcing a chosen number of rounds.
• Customizable transition length to adapt to different material, for example in- and out-of-phase audio data.
• Easily extendable transition mechanism: A very simple API allows scientists and developers to drop-in their own custom transition modules, for example to allow completely seamless switching.

Non-exclusive features:

• Computation of statistical significance (p-value), also known as "probability of guessing".
• Multi-threaded, low resource consumption.
• Cross platform Java binary. Custom Windows and Mac executables.
• Nice and simplistic GUI.
• Textual output for easy publication of results.

Notes:

I could only test on a Mac, yet, where it works flawlessly. Please report wether it also works on other platforms. Input is currently WAV only, and the files must have identical format and length. The program is basically able to work with all PCM integer bit depths up to 32 bit, but in practice one is limited by ones specific JRE's capabilities. Java on the Mac, for example, is limited to 16 bit. High sample rates should not be a problem anywhere. The back-end already supports looping, it just isn't implemented in the GUI code, yet.

The source code is going to be released later on. Please don't drown me in feature requests, actual code submits are much preferred.

Initial Remarks:

1. "Transition Lenght"

2. Windows executable (XP SP3): Play button shows square icon as per stop button.

Same here on Windows XP. Also "play progress marker thing" stops not at the end but about one centimeter to the left of the end point (see screen shot). I can put the marker at the end by repeatedly pressing the play button. When end of file is reached I have to press Stop button to get the marker back to the start point. Hope my description is understandable. :-) Perhaps this is intended behavior.

Fade effect is clearly audible and delayed about one second from the clicking on any Track-button
