Sound effects method for masking delay in a digital audio player

Abstract

The present invention is a method for enhancing playback of digital audio data by playing sound effects stored in a digital audio player's memory. The sound effects are preferably loaded into a playback memory just before an MPU of the player starts to perform a task that normally results in a silent processing delay, such as locating digital audio data. By parallel processing a sound effect with a time consuming task performed by the MPU, the processing delay is not noticed by a user. In addition to filling an otherwise silent interval of time with some sort of entertainment, the sound effects can be used to emulate some of the sounds made by a vintage juke box, such as the crackling of a needle on a record. In an alternative embodiment, the sound effects are stored in a song database such that there can be particular sound effects that are used when a particular song database is to be accessed. For seamlessly playing a song right after a sound effect, the digital audio data of a song selection can be streamed to the same playback memory that is used for playback of the sound effect.
