414 Glossary
If you cut out a portion of a wave and paste it in somewhere else, chances are there will be
a discontinuity where the two waves are joined. This discontinuity will result in a transient in
the wave when it is played back, which is perceived as a "click" or "bump" in the sound. To
avoid this you need to make any editing splices at a zero crossing point.
