Abstract: An apparatus for generating an audio output signal based on an encoded audio signal spectrum is provided. The apparatus has a processing unit for processing the encoded audio signal spectrum to obtain a decoded audio signal spectrum having a plurality of spectral coefficients, wherein each of the spectral coefficients has a spectral location within the encoded audio signal spectrum and a spectral value. Moreover, the apparatus has a pseudo coefficients determiner for determining one or more pseudo coefficients. Furthermore, the apparatus has a replacement unit for replacing at least one or more pseudo coefficients by a determined spectral pattern to obtain a modified audio signal spectrum, wherein each of at least two pattern coefficients has a spectral value. Moreover, the apparatus has a spectrum-time-conversion unit for converting the modified audio signal spectrum to a time-domain.

Abstract: An apparatus for reproducing an audio signal includes a first reproducer configured to reproduce a first portion of the audio signal in a first frequency band based on the first data. A provider is configured to provide a patch signal in a second frequency band, wherein the patch signal is at least partially uncorrelated with respect to the first portion of the audio signal or is at least partially a decorrelated version of the first portion of the audio signal, which has been shifted to the second frequency band. A second reproducer is configured to reproduce a second portion of the audio signal in the second frequency band based on second data and the patch signal. A combiner is configured to combine the reproduced first portion of the audio signal and the patch signal.

Abstract: An apparatus for generating an audio output signal based on an encoded audio signal spectrum has a processing unit, a pseudo coefficients determiner, a spectrum modification unit, a spectrum-time conversion unit, a controllable oscillator and a mixer. The pseudo coefficients determiner is configured to determine pseudo coefficients of the decoded audio signal spectrum. The spectrum modification unit is configured to set the pseudo coefficients to a predefined value to acquire a modified audio signal spectrum. The spectrum-time conversion unit is configured to convert the modified audio signal spectrum to a time-domain. The controllable oscillator is configured to generate a time-domain oscillator signal and is controlled by the spectral location and the spectral value of at least one of the pseudo coefficients. The mixer is configured to mix the time-domain conversion signal and the time-domain oscillator signal.

Abstract: An encoding concept which is linear prediction based and uses spectral domain noise shaping is rendered less complex at a comparable coding efficiency in terms of, for example, rate/distortion ratio, by using the spectral decomposition of the audio input signal into a spectrogram having a sequence of spectra for both linear prediction coefficient computation as well as spectral domain shaping based on the linear prediction coefficients. The coding efficiency may remain even if such a lapped transform is used for the spectral decomposition which causes aliasing and necessitates time aliasing cancellation such as critically sampled lapped transforms such as an MDCT.

Abstract: A disclosed method provides automated scripting to guide a customer service representative (CSR) in handling a call from a customer. Operations within the method may include displaying products and two or more purpose classifications for selection by the CSR. The purpose classifications may include (a) an add classification for customer requests to add a new product to an account and (b) a remove classification for customer requests to remove an existing product from the account. A page generator may receive input from the CSR selecting one of the purpose classifications and one of the products as pertinent to the call. In response, the page generator may automatically displaying a customized page with scripted text for the CSR to read to the customer. The scripted text may correspond specifically both to the selected purpose classification and to the selected product.
