Abstract:
1. A method for encoding an audio signal comprising a first and a directly following second audio track for seamless and individual playback of the first and second audio tracks; wherein the first and second audio tracks comprise a first and second plurality of audio frames, respectively; the method comprising jointly encoding the audio signal using a frame based audio encoder, thereby yielding a continuous sequence of encoded frames; extracting a first plurality of encoded frames from the continuous sequence of encoded frames; wherein the first plurality of encoded frames corresponds to the first plurality of audio frames; extracting a second plurality of encoded frames from the continuous sequence of encoded frames; wherein the second plurality of encoded frames corresponds to the second plurality of audio frames; wherein the second plurality of encoded frames directly follows the first plurality of encoded frames in the continuous sequence of encoded frames; appending one or more rear extension frames to an end of the first plurality of encoded frames; wherein the one or more rear extension frames correspond to one or more frames from a beginning of the second plurality of encoded frames, thereby yielding a first encoded audio file; and appending one or more front extension frames to the beginning of the second plurality of encoded frames; wherein the one or more front extension frames correspond to one or more frames from the end of the first plurality of encoded frames, thereby yielding a second encoded audio file.
