Blind bandwidth extension of audio signals based on non-linear prediction and hidden Markov model
The bandwidth limitation of wideband (WB) audio systems degrades the subjective quality and naturalness of audio signals. In this paper, a new method for blind bandwidth extension of WB audio signals is proposed based on non-linear prediction and hiddenMarkov model (HMM). The high-frequency (HF) components in the band of 7–14 kHz are artificially restored only from the low-frequency information...
متن کاملAn audio watermark-based speech bandwidth extension method
A novel speech bandwidth extension method based on audio watermark is presented in this paper. The time-domain and frequency-domain envelope parameters are extracted from the high-frequency components of speech signal, and then these parameters are embedded in the corresponding narrowband speech bit stream by the modified least significant bit watermark method which uses perception property. At...
متن کاملBandwidth Extension Method Based on Spectral Envelope Estimation
In current communication system, high quality audio signal is supposed to be provided with low bit rate and low computational complexity. This paper proposed a novel audio coding bandwidth extension method, which can improve decoded audio quality with increasing only a few coding bits per frame and a little computational complexity. This method calculate high-frequency synthesis filter by using...
متن کاملBlind Dereverberation of Audio Signals
This project examines the problem of single channel blind dereverberation. After estimating the T60 value, a time-domain binary masking approach was used to remove regions of the signal that were largely dominated by reverberant energy. Performance of the system was examined for several different classes of audio (hand clapping, drums, and speech) and for varying amounts of reverberation. In ad...
متن کاملBandwidth Extension with Hybrid Signal Extrapolation for Audio Coding
In this paper, we propose a blind method using hybrid signal extrapolation at the decoder to regenerate lost high-frequency components which are removed by encoders. At first, a decoded signal spectral resolution is enhanced by time domain linear predictive extrapolation and then the cut off frequency of each frame is estimated to avoid the spectrum gap between the end of original low frequency...
