Abstract: A user interface apparatus for displaying areas having vocal or instrumental unit signals that are included in an input musical tone signal. Display locations, for display on a display screen that has a localization-frequency plane, are calculated for the input musical tone signal based on localization information of each frequency band. Then, the primary level distributions, in which the levels of the frequency band corresponding to each display location are expanded and obtained using a specified distribution in each of the frequency bands, is calculated.

Said secondary level distribution is displayed in three dimensions (the localization axis, the frequency axis, and the level axis) and viewed from the level axis direction. Therefore, the areas, in which the vocal or instrumental units exist in a grouped state, can be easily identified.
