Patent number: 10013970Abstract: A sound effect producing apparatus includes an input portion, a memory portion, a pseudo sound reflection producing portion, and an effect provision portion. The input portion performs inputting of an audio signal. The memory portion stores sound effect information that includes production information for producing a pseudo sound reflection corresponding to a sound reflection generated in a predetermined acoustic space and sound source position information showing a sound source position of the pseudo sound reflection. The pseudo sound reflection producing portion produces a pseudo sound reflection based on the production information. The effect provision portion performs a process of localizing the pseudo sound reflection using a predetermined direction as a reference, based on the audio signal and the sound source position information.Type: GrantFiled: May 24, 2017Date of Patent: July 3, 2018Assignee: YAMAHA CORPORATIONInventor: Morishige Fujisawa

Patent number: 9774980Abstract: An audio processor acquires processed sound data, which is obtained by processing original sound data according to a content of processing defined such that first sound is emitted under the standard sound emission condition, in association with a sound emission device, acquires a control signal, and acquires a device sound emission condition. In order to make second sound emitted by the sound emission device under the acquired device sound emission condition close to the first sound, the audio processor identifies the correction content of the processed sound data based on a difference between the device sound emission condition and the standard sound emission condition, the control signal, and the processed sound data acquired in association with the sound emission device. The audio processor corrects the processed sound data according to the correction content, and supplies the corrected processed sound data to the sound emission device.Type: GrantFiled: January 6, 2016Date of Patent: September 26, 2017Assignee: YAMAHA CORPORATIONInventors: Morishige Fujisawa, Noriyuki Ohashi, Hirochika Maegaki
