    • A processing load at the time of playing back sound data having a loop part is reduced.A sound data encoding apparatus comprises a block dividing means that divides the sound data into blocks according to predetermined rules, and an encoding means that encodes the blocks in groups of a plurality of consecutive blocks. The block dividing means divides the sound data such that, when encoded blocks encoded by the encoding means are decoded to output decoded blocks, then the loop end position in a block that includes the loop end position in the decoded blocks is nearer to an end of the block than a predetermined position. In detail, input delay dummy data are added ahead of the sound data before dividing the sound data. At the time of outputting the encoded data, loop information is outputted also. The loop information includes the number of samples of the added input delay dummy data, the number of samples corresponding to the encoding delay, the number of samples corresponding to the decoding delay, the start and end positions of the sound data, and the loop start and end positions.
    • 在回放具有环路部分的声音数据时的处理负荷减小。 声音数据编码装置包括根据预定规则将声音数据划分成块的块分割装置,以及对多个连续块的组进行编码的编码装置。 块分割装置对声音数据进行分割,使得当由编码装置编码的编码块被解码以输出解码块时,包括解码块中的循环结束位置的块中的循环结束位置更接近于 该块比预定位置。 详细地,在分割声音数据之前,在声音数据之前添加输入延迟伪数据。 在输出编码数据时,也输出循环信息。 循环信息包括所添加的输入延迟伪数据的样本数,对应于编码延迟的采样数,对应于解码延迟的采样数,声音数据的开始和结束位置以及循环开始 和结束位置。

    • Tone quality is improved at the time of playing back sound data having a loop part.A sound data encoding apparatus encodes sound data in groups of a plurality of consecutive blocks. In the case where the sound start position is equal to the loop start position, encoding is performed using samples of sound data (for example, sound data just before the loop end) relating to the sound data at the sound start position from the viewpoint of music. In the case where the sound end position is equal to the loop end position, encoding is performed using samples of sound data (for example, sound data just after the loop start) relating to the sound data at the sound end position from the viewpoint of music.
    • 回放具有循环部分的声音数据时,音质提高。 声音数据编码装置对多个连续块的组中的声音数据进行编码。 在声音开始位置等于循环开始位置的情况下,使用与声音开始位置处的声音数据有关的声音数据(例如,环路结束前的声音数据)的样本从视点开始进行编码 音乐。 在声音结束位置等于循环结束位置的情况下,使用与声音结束位置处的声音数据有关的声音数据(例如,循环开始之后的声音数据)的样本从视点 音乐。
