Project TitleSynthAssist: Efficient Audio Synthesis Using Vocal Imitation
Track Code2014-099
Short Description

A novel easy-to-use audio synthesizer for desired sounds by user vocal imitation and automated computer analysis

#software #analysis #soundsynthesis


Programming an audio synthesizer can be a difficult task for many. The current software-based synthesizers have complex controls and unfriendly interfaces, which limit the productivity of both novice and experienced users. To overcome this barrier, Northwestern researchers developed a novel audio synthesizer system called SynthAssist to help users efficiently find their desired sound in the audio database. In contrast to existing technologies which require users to provide synthesis parameters, Northwestern’s SynthAssist allows a more intuitive way by allowing a user to either vocalize the desired sound or choose examples from a database to initiate the synthesis. This audio synthesis process proceeds through the iterative automated computer analysis based on advanced algorithms and the evaluative feedback from the users. Therefore, with a friendly user interface and a natural approach, SynthAssist makes audio synthesizers more accessible and lets users focus on high-level goals instead of low-level controls.
