Abstract
Gapless looping playback of an audio sound seamlessly without any silence between loops. An uncompressed digital audio file is divided and encoded using an MP3 encoder to produce two encoded files, A and B. The MP3 encoder adds a padding delay at the beginning and end of each file. Two timers are defined: T1=A−(a+b) and T2=B−(d+c), where a is the padding delay at the end of A, b is the delay at the beginning of B, c is the delay at the beginning of A, and d is the delay at the end of B. Simultaneously, a decoder starts to decode A on Track 1 and T1 is started. Immediately after T1 expires, a decoder starts to decode B on Track 2 and T2 is started. Thanks to the timers, the respective end and beginning of the sound portions of A and B temporally align so that no silence is heard.
