The Simplest Form of Edit

FIG. 1: Butt splices align two segments of audio end to end. The butt splice on the left occurs at a zero-crossing, so no pop or click should occur as it will with the edit on the right.

The simplest form of edit involves placing two regions next to each other in time so that one region abruptly stops as the other begins. This type of edit, called a butt splice, is frequently all you need to get the job done. Butt splices have two disadvantages, though. If the splice does not take place at zero-crossings of the waveforms, a tick or pop is often heard (see Fig. 1). In addition, this type of immediate, direct transition can often sound jarring or rough. This is where fades enter the picture.
