Music emotion is a special emotion that is aroused by music which is a media that can convey human affection. Music emotion classification is a popular topic in recent years. The mood of a music clip describes emotional expression. It is helpful in music understanding, music retrieval and some other interesting music related application. In this paper, a method is proposed using a framework named...
Automatically extracting rhythmic information from musical recordings is inarguably one of the most critical subtasks in many systems of music information retrieval. This paper presents a system for automatically extracting rhythm feature of audio music signal in the WAV format by using a new approach based on metric structure and Bayesian theory. In this system, an detected method is applied in the...
Standard MIDI files consist of a number of tracks. Usually, one of them is melody track, and others accompaniment tracks. To recognize the melody track from multiple tracks is important for the music retrieval and other music related applications. Though lots of researchers had researched on this topic, more efficient and precise methods are still needed. An innovative method based on the improved...
This paper presents AudioCycle, a prototype application for browsing through music loop libraries. AudioCycle provides the user with a graphical view where the audio extracts are visualized and organized according to their similarity in terms of musical properties, such as timbre, harmony, and rhythm. The user is able to navigate in this visual representation, and listen to individual audio extracts,...
The development of effective music retrieval and recommendation applications requires meaningful features for characterizing music audio. The rhythm of music audio in particular, besides timbre and melody, is essential in describing the music piece. This paper illustrates how drum loop patterns characterize the salient rhythm structure of music and an approach for drum loop pattern extraction is described...
Many musical genres and styles are characterized by distinct representative rhythmic patterns. In most automatic genre classification systems global statistical features based on timbral dynamics such as mel-frequency cepstral coefficients (MFCC) are utilized but so far rhythmic information has not so effectively been used. In order to extract bar-long unit rhythmic patterns for a music collection...
In this paper, a system that robustly searches and matches a music input signal to a music collection database using a hash table that is constructed from n-grams of reduced tonal profile. Since the problem that is being studied requires high performance, efficiency and scalability, not only the retrieval accuracy should be high, but also the systems workload on the processing unit and the memory...
In this paper, a music instrumentation analysis and identification method is proposed. In contrast to existing systems, it tries to identify the whole instrument set in polyphonic music and also decide whether each instrument actually dominates at a particular moment or not, but without calculating the exact pitch, onset timing, or the volume of each note. Moreover, it does not require the music source...
Music expresses emotion. A number of audio extracted features have influence on the perceived emotional expression of music. These audio features generate a high-dimensional space, on which music similarity retrieval can be performed effectively, with respect to human perception of the music-emotion. However, the real-time systems that retrieve music over large music databases, can achieve order of...
