SoundRuler is a tool for acoustic analysis, graphing and teaching. It interactively recognizes and measures 35 temporal and spectral properties of each sound in a file.
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 speed and objectivity 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.
