摘要: An embodiment of an apparatus (100) for generating audio subband values in audio subband channels comprises an analysis windower (110) for windowing a frame (120) of time-domain audio input samples being in a time sequence extending from an early sample to a later sample using an analysis window function (190) comprising a sequence of window coefficients to obtain windowed samples. The analysis window function (190) comprises a first group (200) of window coefficients and a second group (210) of window coefficients. The first group (200) of window coefficients is used for windowing later time-domain samples and the second group (210) of window coefficients is used for windowing an earlier time-domain samples. The apparatus (100) further comprises a calculator (170) for calculating the audio subband values using the windowed samples.

摘要: An apparatus for generating time-domain audio samples or synthesis filterbank (300) comprises a calculator (310) for calculating a frame (330) comprising a sequence of intermediate time-domain samples from audio subband values of block (320). The calculator (310) is coupled to a synthesis windower (360) to which the frame (330) of intermediate time-domain samples is provided. The synthesis windower (360) is adapted to windowing the sequence of intermediate time-domain samples using a synthesis window function (370) and provides a frame (380) of windowed intermediate time-domain samples. The synthesis windower (360) is coupled to an overlap-adder output stage (400) that obtains a block (410) of time-domain samples. The block (410) of the time-domain (output) samples can then for instance be provided to further components for further processing, storing or transforming into audible audio signals.

摘要: An audio encoder for providing an encoded audio information on the basis of an input audio information comprises a bandwidth extension information provider configured to provide bandwidth extension information using a variable temporal resolution and a detector configured to detect an onset of a fricative or affricate. The audio encoder is configured to adjust a temporal resolution used by the bandwidth extension information provider such that bandwidth extension information is provided with an increased temporal resolution at least for a predetermined period of time before a time at which an onset of a fricative or affricate is detected and for a predetermined period of time following the time at which the onset of the fricative or affricate is detected. Alternatively or in addition, the bandwidth extension information is provided with an increased temporal resolution in response to a detection of an offset of a fricative or affricate. Audio encoders and methods use a corresponding concept.

摘要: A method for processing an audio signal (504) in accordance with a room impulse response is described. The audio signal (504) is processed (502) with an early part of the room impulse response separate from a late reverberation of the room impulse response, wherein the processing (514) of the late reverberation comprises generating a scaled reverberated signal, the scaling (526) being dependent on the audio signal (504). The processed early part (506) of the audio signal (504) and the scaled reverberated signal are combined.
