    • 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.
    • 无缝循环播放音频声音,没有任何循环之间的沉默。 使用MP3编码器对未压缩的数字音频文件进行分割和编码,以产生两个编码文件A和B. MP3编码器在每个文件的开头和结尾添加一个填充延迟。 定义了两个定时器:T1 = A-(a + b),T2 = B-(d + c),其中a是A结束时的填充延迟,b是B开始的延迟,c是 延迟在A的开始,d是在B的结束时的延迟。同时,解码器开始在轨道1上解码A,并且T1被启动。 在T1到期之后,解码器立即开始在轨道2上解码B,并且启动T2。 由于定时器,A和B的声音部分的相应端和开始时间对齐,从而不会听到沉默。
