Fractal Sinusoidal Modelling For Low Bit-Rate Audio Coding
This paper proposes a fractal sinusoidal model that is able to reduce the bit-rate of sinusoidal model coders while achieving perceptually lossless quality. This is achieved by removing the redundancy between sinusoidal tracks through encoding similar tracks with the transformation between a template track and the original track. This paper proposes a transform that is able to capture the perce...
متن کاملSynthesizing breathiness in natural speech with sinusoidal modelling
This paper discusses recent work in synthesizing a breathy quality in pre-recorded speech, which has applications in voice morphing and concatenative TTS. Previous work has shown that the breathy quality in speech is characterized in part by the presence of random noise in the upper region of the spectrum [1]. The sinusoidal modelling representation of speech facilitates making high-quality mod...
متن کاملHigh Accuracy Frame-by-frame Non-stationary Sinusoidal Modelling
This paper describes techniques for obtaining high accuracy estimates, including those of non-stationarity, of parameters for sinusoidal modelling using a single frame of analysis data. In this case the data used is generated from the time and frequency reassigned short-time Fourier transform (STFT). Such a system offers the potential for quasi real-time (frame-by-frame) spectral modelling of a...
متن کاملSinusoidal Modelling for Ecoacoustics
Biodiversity assessment is a central and urgent task, necessary to monitoring the changes to ecological systems and understanding the factors which drive these changes. Technological advances are providing new approaches to monitoring, which are particularly useful in remote regions. Situated within the framework of the emerging field of ecoacoustics, there is growing interest in the possibilit...
متن کاملSimpl: a Python Library for Sinusoidal Modelling
This paper introduces Simpl, a new open source library for sinusoidal modelling written in Python. The library is presented as a resource for researchers in spectral signal processing, who might like to access existing methods and techniques. The text provides an overview of the design of the library, describing its data abstractions and integration with other systems. This is complemented by s...
