Abstract:
A jitter buffer control for controlling a provision of a decoded audio content on the basis of an input audio content is configured to select a frame-based time scaling or a sample-based time scaling in a signal-adaptive manner. An audio decoder uses such a jitter buffer control.

Claim (Index 19):
A jitter buffer control for controlling a provision of a decoded audio content on the basis of an input audio content,\n wherein the jitter buffer control is configured to select a frame-based time scaling or a sample-based time scaling in a signal-adaptive manner; wherein audio frames are dropped or inserted to control a depth of a jitter buffer when the frame-based time scaling is used, and wherein a time-shifted overlap-and-add of audio signal portions is performed when the sample-based time-scaling is used; wherein the jitter buffer control is configured to select a frame-based comfort noise insertion or a frame-based comfort noise deletion for a time scaling if a discontinuous transmission in conjunction with comfort noise generation is currently used or was used for a previous frame, wherein the jitter buffer control is configured to select an overlap-add-operation using a predetermined time shift for a time scaling if a current audio signal portion is active but comprises a signal energy which is smaller than or equal to an energy threshold value, and if a jitter buffer is not empty, or if a previous audio signal portion was active but comprises a signal energy which is smaller than or equal to the energy threshold value, and if the jitter buffer is not empty; wherein the jitter buffer control is configured to select an overlap-add-operation using a signal-adaptive time shift for a time scaling if a current audio signal portion is active and comprises a signal energy which is larger than or equal to the energy threshold value and if the jitter buffer is not empty, or if a previous audio signal portion was active and comprises a signal energy which is larger than or equal to the energy threshold value and if the jitter buffer is not empty; and wherein the jitter buffer control is configured to select an insertion of a concealed frame for a time scaling if a current audio signal portion is active and if the jitter buffer is empty, or if a previous audio signal portion was active and if the jitter buffer is empty.
