鼓 Loop 匹配目标 BPM 后为什么瞬态变糊?3 种渲染方法对照 Why Do Drum-Loop Transients Blur After Tempo Matching? A Three-Render Test
先排除速度、采样率与接缝错误,冻结一份起音表作共同参照;打乱并隐藏当前、鼓类瞬态与原速切片三个候选的标签,再记录起音、重影、尾音、空隙、时间与接缝。 Clear tempo, sample-rate, and join faults first; freeze one onset list as a common reference, hide candidate labels, then score current, percussion-aware, and original-speed sliced renders for attacks, pre-echoes, tails, gaps, timing, and the join.
