延迟 – can be used to duplicate 声 and to 创作 loops asymmetric or irregular 延迟 might be especially interesting

声像 – can be used to spread 声 across the 空间 between left and right enveloping the 听众

混响 – could be used to provide a 感觉 of 声 in 空间 and to place 声 further away more 混响

时间缩放 – could be used to extend 声 and to 创作 interesting 质地（纹理、织体） which could then be layered panned and have 延迟 or 混响 applied to them
