Accurate tempo estimation based on harmonic + noise decomposition
In this paper we present an innovative tempo estimation system that processes acoustic audio signals and does not use any high level musical knowledge. Our proposal relies on a harmonic plus noise decomposition of the audio signal by means of a subspace analysis method. Then, a technique to measure the degree of musical accentuation as a function of time is developed and separately applied to t...
متن کاملMusical Tempo Estimation Using Noise Subspace Projections
Tempo estimation plays a fundamental role in music analysis, especially for the automatic processing of large amounts of musical data. In this paper, a novel idea to enhance the estimation of the tempo in musical pieces is described, based on an harmonic/noise decomposition. This separation of the signal into a deterministic and a stochastic part is performed by projecting the signal onto its n...
متن کاملAccurate Tempo Estimation Based on Recurrent Neural Networks and Resonating Comb Filters
In this paper we present a new tempo estimation algorithm which uses a bank of resonating comb filters to determine the dominant periodicity of a musical excerpt. Unlike existing (comb filter based) approaches, we do not use handcrafted features derived from the audio signal, but rather let a recurrent neural network learn an intermediate beat-level representation of the signal and use this inf...
متن کاملAccurate estimation of sinusoidal parameters in an harmonic+noise model for speech synthesis
We present here an Harmonic+Noise Model (HNM) for speech synthesis. The noise part is represented by an autoregressive model whose output is pitchsynchronously modulated in energy. The harmonic part of the signal is represented by a sinusoidal model. This paper compares di erent methods for separating these two components. We then propose a method for the estimation of the sinusoidal parameters...
متن کاملRobust and accurate fundamental frequency estimation based on dominant harmonic components.
This paper presents a new method for robust and accurate fundamental frequency (F0) estimation in the presence of background noise and spectral distortion. Degree of dominance and dominance spectrum are defined based on instantaneous frequencies. The degree of dominance allows one to evaluate the magnitude of individual harmonic components of the speech signals relative to background noise whil...
