The rhythmic analyzer and equalizer presented here allows to cut or boost the signal at a given audio frequency and a given rhythmic frequency, that is, number of beats per minute (BPM). A task that can be addressed with the rhythmic equalizer is for instance to emphasize series of 8th triplet notes played on the hi-hat of a drum set. The software works in real time and offers an interactive graphical user interface that supports both analysis and adjustment. The current energy distribution in the two-dimensional audio frequency / BPM space is displayed as a continuously updated backdrop image. The user paints the intended adjustments of levels and phases onto an image layer on top of this image.
