Using Spectro-Temporal Features for Environmental Sounds Recognition
The paper presents the task of recognizing environmental sounds for audio surveillance and security applications. A various characteristics have been proposed for audio classification, including the popular Mel-frequency cepstral coefficients (MFCCs) which give a description of the audio spectral shape. However, it exist some temporal-domain features. These last have been developed to character...
متن کاملDispersive and Pitch-Synchronous Processing of Sounds
The aim of this paper is to present results on digital processing of sounds by means of both dispersive delay lines and pitch-synchronous transforms in a unified framework. The background on frequency warping is detailed and applications of this technique are pointed out with reference to the existing literature. These include transient extraction, pitch shifting, harmonic detuning and auditory...
متن کاملPitch Perception of Complex Sounds: Nonlinearity Revisited
The ability of the auditory system to perceive the fundamental frequency of a sound even when this frequency is removed from the stimulus is an interesting phenomenon related to the pitch of complex sounds. This capability is known as “residue” or “virtual pitch” perception and was first reported last century in the pioneering work of Seebeck. It is residue perception that allows one to listen ...
متن کاملRelative-pitch tracking of multiple arbitrary sounds.
Perceived-pitch tracking of potentially aperiodic sounds, as well as pitch tracking of multiple simultaneous sources, is shown to be feasible using a probabilistic methodology. The use of a shift-invariant representation in the constant-Q domain allows the modeling of perceived pitch changes as vertical shifts of spectra. This enables the tracking of these changes in sounds with an arbitrary sp...
