About:
eXtace is a visual sound display/analysis program. It requires Esound (esd) for its audio source. It includes various fast fourier transforms of the audio data in realtime. Its displays include a 3D wireframe flying landscape, a 3D textured flying landscape, a 16-256 channel graphic EQ, three types of scopes, a 3D "spike" flying landscape, and two forms of spectragrams. The 3D traces can be picked up, manipulated, and displayed at nearly any angle. eXtace also features a 3D direction control widget for controlling the angle and speed at which the trace runs away and a gradient/colormap editor for changing the colormap to suit your needs. No OpenGL is required.

Release focus: Minor feature enhancements

Changes:
Cosmetic improvements were made to the Options panel. FFTW-3.x support was added. eXtace will detect the presence of FFTW-2.x or 3.x during compilation and select the best version. (FFTW-3.x is recommended, as FFTW-2.x can cause an eXtace crash when switching FFT sizes.) Scope zooming is supported to allow zooming in or out of the trace in the time domain, which is useful to see high frequency signals.

[»] New vs. old versions
by Michael T. Babcock - Nov 18th 2000 07:54:50

Unlike some programs, extace actually loses some features from version to version -- there were visuals I liked in the older versions that aren't available in the newer ones at all. Take a look at different versions if you want to see the whole gamut of options.
