Improving Sound Quality by Bandwidth Extension
In recent telecommunications system uses a limited audio signal bandwidth of 300 to 3400 Hz. In recent times it has been proposed that the mobile phone networks with increased audio signal bandwidth of 50Hz-7 KHz will increase the sound quality of the speech signal. In this paper, a method extending the conventional narrow frequency band speech signals into a wideband speech signals for improve...

15 صفحه اولExperimental validation of acoustic intensity bandwidth extension by phase unwrapping.
The phase and amplitude gradient estimator (PAGE) method for active acoustic intensity uses pairwise microphone transfer functions to obtain the phase gradient, which improves the calculation bandwidth over the traditional weighted quadspectral method. Additionally, for broadband sources, the PAGE theory indicates that the transfer function phase can be unwrapped to further extend the usable fr...
متن کاملSpeech enhancement using STC-based bandwidth extension
Telephone speech is typically bandlimited to 4 kHz, resulting in a ‘muffled’ quality. Coding speech with bandwidth greater than 4 kHz reduces this distortion, but requires a higher bit rate to avoid other types of distortion. An alternative to coding wider bandwidth speech is to exploit correlation between the 0-4 kHz and 4-8 kHz speech bands to resynthesize wideband speech from narrowband spee...
متن کاملCodebook-based Bandwidth Extension with Side-Information
With the Bandwidth Extension (BWE) techniques it is possible to enhance the bandwidth of limited speech signals and provide backward compatibility with respect to the communication networks. Artificial Bandwidth Extension (ABWE) uses correlations between the low and the high frequency ranges, to predict a wideband signal outgoing from a narrowband signal [1, 2]. The advantage of the ABWE techni...
