Application ID: 13159815

Base Claim:
1. A method of time-compressing audio data, comprising: receiving audio data and storing the audio data in a frame buffer of an audio-processing apparatus; selecting a cut point in the audio data by the audio-processing apparatus, separating a first segment of the audio data and a second segment of the audio data, wherein the cut point is selected to prevent audio data compressed in a first iteration of the method from being compressed in a second iteration of the method, and wherein the cut point defines the second segment to have a length no greater a maximum overlap length value; calculating an overlap length of the first segment and the second segment, responsive to characteristics of the audio data; and overlapping by a time compression logic of the audio-processing apparatus the overlap length of the second segment on the first segment, generating an output audio data, wherein the overlap length is randomly reduced if the audio data comprises unvoiced speech or silence for more than a threshold number of audio frames.

Claim 3:
3. The method of claim 1 , wherein the zero is a valid overlap length value.
