摘要： A method and apparatus for generating an audio notification file for a computing device are provided. A first audio file associated with a first mental state is selected as a first section of the audio notification file. The audio notification file enabled for storage in a memory. The audio notification file is further enabled for processing by a processing unit to control a speaker. A final state of the audio notification file is determined, the final state designated as a final section of the audio notification file, the final state associated with a second mental state. At least one intermediate section of the audio notification file is generated, between the first section and the second section, by morphing the first audio file to the final state by processing the first audio file using a digital signal processor.
