[hal-00467532, v1] Multi-scale frame-based analysis of audio signals for musical transcription using a dictionary of chromatic waveforms
نویسنده
چکیده
A new method for analyzing audio signals in the context of musical transcription is described. It consists of a framebased expansion of the signal over a multi-scale time-frequency dictionary with a set of logarithmic discrete frequencies. This method, based on the Matching Pursuit algorithm, provides the same frequency resolution as a constantQ filter-bank, but with a better time resolution, especially in low frequencies, and an efficient noise rejection.

Speech Enhancement using Adaptive Data-Based Dictionary Learning
In this paper, a speech enhancement method based on sparse representation of data frames has been presented. Speech enhancement is one of the most applicable areas in different signal processing fields. The objective of a speech enhancement system is improvement of either intelligibility or quality of the speech signals. This process is carried out using the speech signal processing techniques ...
متن کامل[hal-00695758, v1] An informed source separation system for speech signals
In two previous papers, we proposed an audio Informed Source Separation (ISS) system which can achieve the separation of I > 2 musical sources from linear instantaneous stationary stereo (2-channel) mixtures, based on audio signal’s natural sparsity, pre-mix source signals analysis, and side-information embedding (within the mix signal). In the present paper and for the first time, we apply thi...
متن کاملA New Method for Speech Enhancement Based on Incoherent Model Learning in Wavelet Transform Domain
Quality of speech signal significantly reduces in the presence of environmental noise signals and leads to the imperfect performance of hearing aid devices, automatic speech recognition systems, and mobile phones. In this paper, the single channel speech enhancement of the corrupted signals by the additive noise signals is considered. A dictionary-based algorithm is proposed to train the speech...
متن کاملBayesian analysis of polyphonic western tonal music.
This paper deals with the computational analysis of musical audio from recorded audio waveforms. This general problem includes, as subtasks, music transcription, extraction of musical pitch, dynamics, timbre, instrument identity, and source separation. Analysis of real musical signals is a highly ill-posed task which is made complicated by the presence of transient sounds, background interferen...
متن کاملA Review on Signal Decomposition Techniques
Analysis of audio and musical information signals deals with the decomposition into atoms. This subject is most interesting and useful for the researchers who want to invent the inherent properties of the signal under decomposition and to construct a new version of it. Many algorithms have been proposed for the decomposition of audio and musical content and methodologies have been demonstrated ...
