In this paper, an efficient, general-purpose model for multiple instrument polyphonic music transcription is proposed. The model is based on probabilistic latent component analysis and supports the use of sound state ...

This work presents a spectrogram factorisation method applied to automatic music transcription of a cappella performances with multiple singers. A variable-Q transform representation of the audio spectrogram is factorised ...

This paper introduces a model of environmental acoustic scenes which adopts a morphological approach by ab-stracting temporal structures of acoustic scenes. To demonstrate its potential, this model is employed to evaluate ...
