SoundRuler is a tool for measuring and graphing sound and for teaching acoustics.
It is open code and free. Like scientific knowledge, it is available for all to use, criticize, adapt to their needs and improve on.
Its visual interactive approach to analysis brings you the best of two worlds: the control of manual analysis and the objectivity and speed of automated analysis.
SoundRuler is specially useful in the analysis of simple, repetitive signals. They can be measured quickly and in great detail, pulse by pulse.
