Abstract (en)
A pair of sets of audio blocks is determined from a multi-channel audio signal. The pair comprises a first set for a first time block over audio channels and a second set for a second time block over the audio channels. Audio features including inter-channel audio features are generated from the pair. The audio features are graphically presented with user interface components on a display page. A specific perceptible audio characteristic is visually conveyed to the user using the user interface components dynamically updated with sets of audio features computed from pairs of sets of audio blocks of the multi-channel audio signal.
