Ghost Viewer is a simple spectrogram visualization plugin. It is designed to smoothly display the sound of a track while playing. It can be used to detect problems on a sound, or simply to have a visual feedback of a sound being processed.



Comparison with the Ghost-X software

Ghost Viewer is optimized for spectrogram visualization, with a minimal set of controls. It is well designed to display the sound of a track while processing the sound. It doesn’t provide editing features but it is lighter in terms of processing resources.

Ghost-X is optimized for sound visualization and editing. It provides a full set of features for editing spectrograms and inspecting small details of spectrograms.
