A New Spectral-Based Approach to Query-by-Humming for MP3 Songs Database
نویسندگان
چکیده
In this paper, we propose a new approach to query-by-humming, focusing on MP3 songs database. Since MP3 songs are much more difficult in melody representation than symbolic performance data, we adopt to extract feature descriptors from the vocal sounds part of the songs. Our approach is based on signal filtering, sub-band spectral processing, MDCT coefficients analysis and peak energy detection by ignorance of the background music as much as possible. Finally, we apply dual dynamic programming algorithm for feature similarity matching. Experiments will show us its online performance in precision and efficiency. Keywords—DP, MDCT, MP3, QBH.

متن کاملA Query by Humming system using MPEG - 7 Descriptors
Query by Humming (QBH) is a method for searching in a multimedia database system containing meta data descriptions of songs. The database can be searched by hummed queries, this means that a user can hum a melody into a microphone which is connected to the computer hosting the system. The QBH system searches the database for songs which are similar to the input query and presents the result to ...
متن کاملComparisong: Audio Comparison Engine
In this paper we present CompariSong a resolver of the query by humming task for a real audio information system. It compares a database of popular songs with a hummed-by-user melody and returns the closest matches. The proposed system performs audio indexing based on perceptual characteristics of the songs rather than the hitherto applied approach that uses manual metadata like text tags. We e...

Music information retrieval is a field of rapidly growing commercial interest. This paper describes TANSEN, a query-by-humming based music retrieval system under development at IIT, Bombay. Named after the legendary musician (and a tenuous acronym for “TA-Note Song ExtractorNavigator), the system is designed to accept acoustic queries in the form of sung fragments, to search a database of India...
متن کاملHum-a-song: A Subsequence Matching with Gaps-Range-Tolerances Query-By-Humming System
We present “Hum-a-song”, a system built for music retrieval, and particularly for the Query-By-Humming (QBH) application. According to QBH, the user is able to hum a part of a song that she recalls and would like to learn what this song is, or find other songs similar to it in a large music repository. We present a simple yet efficient approach that maps the problem to time series subsequence m...
