采样 Synthesis

The 术语 采样 derives from 确定(建立) notions of 数字 采样 and 采样 率 采样 乐器 with or without 樂/乐 keyboards are widely available All 采样 乐器 are designed around the 基础 概念 of playing back prerecorded 声 移位/偏移 to the desired 音高

Instead of scanning a small 固定 波表 包括 one 周期 of a 波形 a 采样 系统 scans a large 波表 that 包含 thousands of individual cyclesseveral seconds of prerecorded 声波 Since the 采样 波形 changes over the 起(始) 延(续) and 衰(减) portion of the 事件 the result is a rich and 时变 声波 The 长 of the 采样 波表 can be arbitrarily long 限制 only by the 内存(记忆) capacity of the 采样器
