Sparse representations of polyphonic music
We consider two approaches for sparse decomposition of polyphonic music: a timedomain approach based on shift-invariant waveforms, and a frequency-domain approach based on phase-invariant power spectra. When trained on an example of a MIDI-controlled acoustic piano recording, both methods produce dictionary vectors or sets of vectors which represent underlying notes, and produce component activ...
متن کاملHaskore Music Notation - An Algebra of Music
We have developed a simple algebraic approach to music description and composition called Haskore In this framework musical objects consist of primitive notions such as notes and rests operations to transform musical objects such as transpose and tempo scaling and operations to combine musical objects to form more complex ones such as concurrent and sequential composition When these simple noti...
متن کاملLearning to Align Polyphonic Music
We describe an efficient learning algorithm for aligning a symbolic representation of a musical piece with its acoustic counterpart. Our method employs a supervised learning approach by using a training set of aligned symbolic and acoustic representations. The alignment function we devise is based on mapping the input acousticsymbolic representation along with the target alignment into an abstr...
متن کاملAzimuth Estimation in Polyphonic Music
Most of the research in music information retrieval (MIR) is concentrating only on monophonic source signals. The stereo information has been ignored largely in the research many years. However, commercially available music recordings typically consist of a two-track stereo mix. The type of mixing process used in the recordings can be roughly categorizes into live recordings and studio recordings.
متن کامل----A Versatile Polyphonic Music Dataset
This is a polyphonic music dataset which can be used for versatile research problems, such as Multi-pitch Estimation and Tracking, Audio-score Alignment, Source Separation, etc. This dataset consists of the audio recordings of each part and the ensemble of ten pieces of four-part J.S. Bach chorales, as well as their MIDI scores, the ground-truth alignment between the audio and the score, the gr...
