We introduce MedleyDB: a dataset of annotated, royalty-free multitrack recordings. The dataset was primarily developed to support research on melody extraction, addressing important shortcomings of existing collections. For each song we provide melody f 0 annotations as well as instrument activations for evaluating automatic instrument recognition. The(More)
The continued growth of MIR is motivating more complex annotation data, consisting of richer information, multiple annotations for a given task, and multiple tasks for a given music signal. In this work, we propose JAMS, a JSON-based music annotation format capable of addressing the evolving research requirements of the community, based on the three core(More)
Due to the scarcity of labeled data, most melody extraction algorithms do not rely on fully data-driven processing blocks but rather on careful engineering. For example, the Melodia melody extraction algorithm employs a pitch contour selection stage that relies on a number of heuristics for selecting the melodic output. In this paper we explore the use of a(More)
A common area of research within music technology is the automatic generation of musical accompaniment. Of particular interest is the generation of harmonic accompaniment to melody. While there are many approaches to solving this problem, the use of various types of finite state machines is popular. One such finite state machine, the finite state transducer(More)
RachelBittner ABSTRACT Interactive music systems are an ideal exploration ground for the testing and incorporation of decision-making algorithms and music informatics techniques into real-time applications. The interactive music system, 'The Harmonically Ecosystemic Machine; Sonic Space No. 7', is the composi-tional result of such a collaboration between(More)
BACKGROUND Despite the positive impact of targeted therapies on metastatic renal cell carcinoma (mRCC), durable responses are infrequent and an unmet need exists for novel therapies with distinct mechanisms of action. We investigated the combination of recombinant Interleukin 21 (IL-21), a cytokine with unique immunostimulatory properties, plus sorafenib, a(More)
When recording a live musical performance, the different voices, such as the instrument groups or soloists of an orchestra, are typically recorded in the same room simultaneously, with at least one microphone assigned to each voice. However, it is difficult to acoustically shield the microphones. In practice, each one contains interference from every other(More)
This work explores the use of source-filter models for pitch salience estimation and their combination with different pitch tracking and voicing estimation methods for automatic melody extraction. Source-filter models are used to create a mid-level representation of pitch that implicitly incorporates timbre information. The spectrogram of a musical audio(More)
Humans may be exposed to whole-body vibration in environments where clear speech communications are crucial, particularly during the launch phase of space flight and in high-performance aircraft. Prior research has shown that high levels of vibration cause a decrease in speech intelligibility. However, the effects of whole-body vibration upon speech are not(More)
