Realtime Audio Visualizer using eSound eXtace is a Audio Visualization plugin for the X-Window System. It connects to ESD (Enlightened Sound Daemon) and displays the audio data as either a pseudo 3D flying landscape, pseudo 3D pointed landscape, 16-256 channel graphic EQ, multi-mode Oscilloscopes, Horizontal Spectrogram, or a combination Hi-res FFT with a Vertical Spectrogram. All modes are fully scalable to nearly ANY resolution! (within your CPU/X11 capabilities) Resolutions up to 1600x1200 at 40 FPS use typically less than 30% CPU, depending on your host CPU/X11 capabilities.
