A new method for estimating the fundamental frequencies of concurrent musical sounds is described. The method is based on an iterative approach, where the fundamental frequency of the most prominent sound is estimated, the sound is subtracted from the mixture, and the process is repeated for the residual signal. For the estimation stage, an algorithm is proposed which utilizes the frequency relationships of simultaneous spectral components, without assuming ideal harmonicity. For the…

Monaural Musical Sound Separation Based on Pitch and Common Amplitude Modulation

A sinusoidal modeling-based separation system that can effectively resolve overlapping harmonics based on the observations that harmonics of the same source have correlated amplitude envelopes and that the change in phase of a harmonic is related to the instrument's pitch is introduced.

Pitch Estimation by the Pair-Wise Evaluation of Spectral Peaks

The pitch estimation was developed for the identication of the predominant voice in polyphonic music recordings and was evaluated as part of a melody extraction algorithm during the Music Information Retrieval Evaluation eXchange (MIREX 2006 and 2009), where the algorithm reached the best overall accuracy as well as very good performance measures.

The proposed method is based on a signal model that includes the panning parameters of the sources in a stereophonic mixture, such as those applied artificially in a recording studio, and provides a full parameterization of the components of the observed signal.

Multiple Fundamental Frequency Estimation by Modeling Spectral Peaks and Non-Peak Regions

This paper proposes an iterative greedy search strategy to estimate F0s one by one, to avoid the combinatorial problem of concurrent F0 estimation, and proposes a polyphony estimation method to terminate the iterative process.

Multiple Fundamental Frequency Estimation by Summing Harmonic Amplitudes

A conceptually simple and computationally efficient fundamental frequency (F0) estimator for polyphonic music signals and three different estimators are proposed: a “direct” method, an iterative estimation and cancellation method, and a method that estimates multiple F0s jointly.

A novel computationally efficient method for estimating multiple pitches (multi-F0) in complex audio signals based on an iterative approach that can not only estimate predominant pitch for human sounds and instrumental sounds the same well regardless of their different harmonic structures, but also can robustly estimate multiple pitches.

A predominant-F0 estimation method called PreFEst is proposed that does not rely on the F0's unreliable frequency component and obtains the most predominant F0 supported by harmonics within an intentionally limited frequency range.

Separation of concurrent harmonic sounds: Fundamental frequency estimation and a time-domain cancell
