Generating tones by combining sound materials

摘要

The apparatus displays, on a display screen, an icon placement region having a time axis defined therein, and displays, in accordance with an input instruction, an icon image with which feature amount information of material data indicative of a sound material is associated. The apparatus further sets a type of a feature amount database, where material data and feature amount information of the material data are associated with each other, along the time axis in accordance with an input instruction. Then, the apparatus references the feature amount database of a type having correspondence relationship in time axis with an icon image to identify material data similar to the feature amount information corresponding to the icon image, and audibly generates a sound at timing corresponding to a position, on the time axis, of the icon image and with content corresponding to the identified material data.

主权项

1. A sound generation control apparatus comprising:
a display control section configured for displaying, on a display screen, an image of an icon placement region having a time axis and for displaying, in the icon placement region, an icon image in association with a desired time position on the time axis, wherein feature amount information is associated with the icon image, the feature amount information comprising a feature amount in the form of a value descriptive of a feature of material data comprising a waveform of a sound material, the value based on the material data comprising the waveform of the sound material; a setting section configured for setting, in association with a desired time range on the time axis of the icon placement region, a particular database to be used, the particular database being selected from among a plurality of types of databases configured for storing material data in association with feature amount information; and a sound generation control section configured for acquiring, on the basis of the feature amount information associated with the icon image, the material data from the database set in association with the time range containing the time position where the icon image is placed, and for generating tone data on the basis of the acquired material data and the time position where the icon image is placed.
