A method for generating an audio notification file for a computing device (150, 601, 701) comprising a processing unit (152, 622, 722) interconnected with a memory (156, 626, 726) and a speaker (155, 655, 755), said method comprising: selecting a first audio file associated with a first mental state as a first section of said audio notification file, said first audio file comprising at least one of a polyphonic file and a music file, said audio notification file enabled for storage in said memory (156, 626, 726), said audio notification file further enabled for processing by said processing unit (152, 622, 722) to control said speaker (155, 655, 755); determining a final state of said audio notification file, said final state associated with a second mental state and designated as a final section of said audio notification file, said final section comprising at least one of a square wave file, an alarm sound and a file comprising abrupt jarring sounds; generating at least one intermediate section of said audio notification file, between said first section and said final section, by morphing said first audio file to said final state by processing said first audio file using a digital signal processor (123, 623, 723); adding markers to said audio notification file to mark transitions between each said section of said audio notification file, wherein each of said sections is associated with a given level of urgency; storing said audio notification file in said memory (156, 626, 726) of said computing device (150, 601, 701); determining that at least one of said sections is associated with a level of urgency of a given notification; selecting said at least one of said sections based on said markers; and playing said at least one of said sections associated with said level of urgency in response to determining that said given notification is to be provided. selecting a first audio file associated with a first mental state as a first section of said audio notification file, said first audio file comprising at least one of a polyphonic file and a music file, said audio notification file enabled for storage in said memory (156, 626, 726), said audio notification file further enabled for processing by said processing unit (152, 622, 722) to control said speaker (155, 655, 755); determining a final state of said audio notification file, said final state associated with a second mental state and designated as a final section of said audio notification file, said final section comprising at least one of a square wave file, an alarm sound and a file comprising abrupt jarring sounds; generating at least one intermediate section of said audio notification file, between said first section and said final section, by morphing said first audio file to said final state by processing said first audio file using a digital signal processor (123, 623, 723); adding markers to said audio notification file to mark transitions between each said section of said audio notification file, wherein each of said sections is associated with a given level of urgency; storing said audio notification file in said memory (156, 626, 726) of said computing device (150, 601, 701); determining that at least one of said sections is associated with a level of urgency of a given notification; selecting said at least one of said sections based on said markers; and playing said at least one of said sections associated with said level of urgency in response to determining that said given notification is to be provided.
