This is abx version 0.2.1.  See the file NEWS for user-visible
changes.

abx is a program for performing software-based audio ABX testing.  ABX
test is a simple statistical method for assessing whether you are able
to tell for audible differences between two samples.  For example, one
sample can be a compressed audio file, such as an Ogg Vorbis, and the
another one its uncompressed variant (WAV, AU, ...).  You can then use
abx to infer whether you are able to separate the two samples due to
compression artifacts.

You will need the following libraries to compile abx:

    * libsndfile (any recent version should do)
    * PortAudio V19
    * GTK+ version 3.24 (other 3.x versions may work as well)

For generic compilation and installation instructions, see the file
INSTALL.  For usage and other information, see

Note about the icons: the distributed src/abx-*.png files are
renderings of src/abx.svg in various resolutions.  If you wish to
modify them, it may be easiest to edit abx.svg and use, for example,
rsvg-convert(1) to recreate the PNG files.
