An Accurate, efficient, and stable system to estimate the unknown input frequency of a
sinusoidal signal is presented. The proposed design solves the main drawback of the …

This paper makes a survey of the numerous analysis methods proposed in order to extract
the frequency, amplitude, and phase of sinusoidal components from stationary sounds …

Precise pitch is important to musicians. We created algorithms for real-time pitch detection
that generalise well over a range of single 'voiced'musical instruments. A high pitch …

We propose a sinusoidal synthesis method based on instantaneous frequency (IF)
attractors, which correspond to harmonic frequency trajectories. The algorithm is novel in …

This paper presents the timbre model, a signal model which has been built to better
understand the relationship between the perception of timbre and the musical sounds most …

The robust estimation of the frequency of some sinusoidal components is a major
prerequisite for many applications, such as in sinusoidal sound modeling, where the …

In the context of non-stationary sinusoidal modeling, this paper introduces the generalization
of the derivative method (presented at the first DAFx edition) for the analysis stage. This new …

The central topic of this chapter is the separation of the audio signal into its source signal
and a time‐varying filter derived from the spectral envelope of the signal. These two features …

In this paper we present a technique for detecting the pitch of sound using a series of two
forward Fourier transforms. We use an enhanced version of the Fourier transform for a better …

This paper presents a special window function for a Fast Fourier Transform (FFT) based
spectral modeling approach for signals consisting of sinusoids plus noise. The main new …
