Concepts for Hybrid Audio Coding SchemesBased on Parametric
نویسندگان
چکیده
Recently an audio coding technique based on a signal representation by parameters describing harmonic tones, individual sinusoidal components and noise components has been presented, which shows its highest eeciency at very low bit rates. In this paper concepts for combination with other techniques for extending the applicability at higher bit rates and for improving the quality in the presence of speech are presented.

Very low bit rate parametric audio coding
In this thesis, a parametric audio coding system for very low bit rates is presented. It is based on a generalized framework that combines different source models into a hybrid model and thereby permits flexible utilization of a broad range of source and perceptual models. The developed parametric audio coding system allows efficient coding of arbitrary audio signals at bit rates in the range o...
متن کاملA New Hybrid Method for Colored Image Steganography Based On DWT
Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...

متن کاملAdvances in Parametric Audio Coding
Parametric modelling provides an efficient representation of general audio signals and is utilised in very low bit rate audio coding. It is based on the decomposition of an audio signal into components which are described by appropriate source models and represented by model parameters. Perception models are utilised in signal decomposition and model parameter coding. This paper gives a brief t...
