Abstract:
Playback by a decoder of a lossy compressed digital media file without quantization gaps is disclosed. The digital media file can be formed of a number of audio samples grouped into a corresponding number of audio frames. As a method, one embodiment can be carried out by identifying an encoder used to compress the digital media file; obtaining an encoder delay value for the identified encoder; obtaining a decoder delay value for the decoder; determining a audio sample count corresponding to a last valid audio sample; setting a re-synchronization after seek option marker N audio frames from the last valid audio sample; and decoding valid audio samples using the encoder delay value, the decoder delay value, and the sample count corresponding to the last valid audio sample.
