SYSTEM AND METHOD FOR GENERATING RING TONE/RING BACK TONE BASED ON USER PREFERENCE MELODY PART BY REAL-TIME MUSIC IDENTIFICATION

摘要

A bell sound and/or RBT(Ring Back Tone) generation system of a user preference melody section through real-time music recognition and a method are provided to detect a sound source and an offset position through music recognition if a user inputs a particular melody section of the preferred sound source as an audio query, thereby offering the particular melody section of the sound source as a bell sound and/or an RBT according to the personal preference of a user. An audio query input unit(104) inputs a melody section of particular music selected by a user as an audio query. An audio fingerprint extractor(105) extracts audio fingerprints for a music signal outputted from the input unit(104). A music DB(103) indexes meta data of a lot of music and audio fingerprints to store the indexed data and fingerprints. A music recognition and information searcher(106) recognizes music by matching the extracted audio fingerprints with the stored audio fingerprints, and searches meta information of the recognized music. An offset searcher(107) detects a user's preferred particular melody section from the DB(103) for the recognized music. A bell sound and/or RBT generator(108) generates a bell sound and/or an RBT as the detected particular melody section.
