Modifying transients for efficient coding of audio
نویسندگان
چکیده
In this paper, we propose a method for eÆcient representation of transients in audio signals. We estimate the transient component of an original audio signal and modify the locations of the transients in such a way that the transients can occur only at locations de ned by a relatively coarse time grid. This procedure allows an eÆcient representation of transients with damped sinusoids. We also verify that the introduced modi cations do not result in a perceptual difference between the original and the modi ed audio signals.

An Efficient Algorithm for Output Coding in Pal Based Cplds (TECHNICAL NOTE)
One of the approaches used to partition inputs consists in modifying and limiting the input set using an external transcoder. This method is strictly related to output coding. This paper presents an optimal output coding in PAL-based programmable transcoders. The algorithm can be used to implement circuits in PAL-based CPLDs.
متن کاملParameter Estimation and Tracking for Time-varying Sinusoids
Parametric modeling permits an efficient representation of audio signals and is increasingly utilized for very low bit rate coding applications. Such systems are based on a decomposition of the audio signal into components that are described by appropriate source models and represented by model parameters. Commonly used components types are sinusoidal trajectories, harmonic tones, transients, a...
متن کاملSuppression of transients in time-varying recursive filters for audio signals
A new method for suppressing transients in time-varying recursive filters is proposed. The technique is based on modifying the state variables when the filter coefficients are changed so that the filter enters a new state smoothly without transient attacks, as originally proposed by Zetterberg and Zhang. In this contribution we modify the Zetterberg–Zhang algorithm to render it feasible for eff...
متن کاملA Switched Parametric & Transform Audio Coder
In this paper, we present a system of sines+transients+noise modeling techniques that dynamically switches between parametric representations and transform coding based representations. The sines and noise are represented by parametric models using multiresolution sinusoidal modeling and Bark-band noise modeling, respectively. The transients are modeled by short regions of transform coding. In ...
متن کاملPost-processing modifications in a parametric audio coder
This paper deals with the modifications of the audio signal in a parametric audio coder at the decoder stage. The parametric audio coder is based on the application of adaptive signal models for each audio signal component. These adaptive signal models are obtained by using different approaches so as to extract a multi-part model from the audio signal. The audio signal is supposed to be constit...
