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 Notes: A segfault which occurred when the options panel was open due to a threading error was fixed.
Release Notes: This version was ported to GTK+ 2.x. The imlib dependencies were removed.
Release Notes: Fixed axis scales for 2D Graphical EQ (linear scale only) and all high res modes when decimation is set to any value greater than 1.
Release Notes: A buffer overflow read error in the audio processing code was fixed. A long time rhythmic glitch in the FFT displays was solved.
Release Notes: 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.
