SPECTRUM 3D: 3D AUDIO SPECTRUM ANALYSER IN REAL TIME
Spectrum 3D displays a 3D audio spectrogram in real time; the source can be either the microphone or an audio file; it is also possible to record a file and to have it analysed; so analysis can be done done on the fly (harmonics are displayed while the audio file is being played), or before the file is being played (in that case, the analysis of the whole will be performed and displayed, then the file can be played afterwards). It is compatible with jack (jack-audio-connection-kit). Optionally, it supports multitouch gestures from touchscreen. It is build with the Gstreamer, SDL 1 or 2, OpenGl, GTK2 or GTK3 and is under GPL license. It is written for Ubuntu but works for other Linux distributions.
Spectrum3d can be compiled against GTK2 or GTK3, against Gstreamer0.1 or Gstreamer1 and against SDL 1 or SDL2. Multitouch is now handled entirely by SDL2.
