Extraction of Drum Tracks from Polyphonic Music Using Independent Subspace Analysis
The analysis and separation of audio signals into their original components is an important prerequisite to automatic transcription of music, extraction of metadata from audio data, and speaker separation in video conferencing. In this paper, a method for the separation of drum tracks from polyphonic music is proposed. It consists of an Independent Component Analysis and a subsequent partitioni...
متن کاملModelling High-Dimensional Sequences with LSTM-RTRBM: Application to Polyphonic Music Generation
We propose an automatic music generation demo based on artificial neural networks, which integrates the ability of Long Short-Term Memory (LSTM) in memorizing and retrieving useful history information, together with the advantage of Restricted Boltzmann Machine (RBM) in high dimensional data modelling. Our model can generalize to different musical styles and generate polyphonic music better tha...
متن کاملAutomatic justification and line-breaking of music sheets
Automated music formatting helps composers and copyists to speed up the process of music score editing by facilitating complex evaluations needed to produce music sheets in terms of symbol positioning, justification, etc. Music justification is a complex task to be automatically performed. It involves the evaluation of a large number of parameters and requires context evaluation. In this paper,...
متن کاملAutomatic Drum Sound Description for Real-World Music Using Template Adaptation and Matching Methods
This paper presents an automatic description system of drum sounds for real-world musical audio signals. Our system can represent onset times and names of drums by means of drum descriptors defined in the context of MPEG-7. For their automatic description, drum sounds must be identified in such polyphonic signals. The problem is that acoustic features of drum sounds vary with each musical piece...
متن کاملAutomatic Transcription of Polyphonic Music Exploiting Temporal Evolution
Automatic music transcription is the process of converting an audio recording into a symbolic representation using musical notation. It has numerous applications in music information retrieval, computational musicology, and the creation of interactive systems. Even for expert musicians, transcribing polyphonic pieces of music is not a trivial task, and while the problem of automatic pitch estim...
