DFreqTIP - Avoiding Clicks with Crossfading
If you have one of my books, you can find a more detailed explanation on the following pages: Cakewalk Power (pages 154-155); Sound Forge Power (pages 135-136); Sonar Power (pages 142-143); Sonar 2 Power (pages 155-156); Sound Forge 6 Power (pages 128-129); Sonar 3 Power (pages 128-129).
One way to make sure your audio waveforms line up at any spice point is to use crossfading. This procedure smoothly fades one audio waveform into another, thus eliminating any potential clicks or pops. You should be able to find a crossfading function in most good audio editing applications, but here are the steps to take when using Sound Forge:
1) Open audio file A and audio file B.
2) Select all the data in audio file B.
3) In audio file A, place the Current Position Cursor at the splice point (the point at which you want to insert audio file B).
4) Choose Edit > Paste Special > Crossfade to open the Crossfade dialog box.
5) Choose the Normal Crossfade preset to have audio file A fade out slowly and audio file B fade in slowly. Or choose the Fast In preset for a quicker fade. You'll usually want to use a quicker fade if you don't want the listener to hear the transition between the two files.
6) Click OK.
[Note: If you are piecing two different songs together, you can do the crossfade at a point in audio file A (usually the end) where there is silence.]
Following this procedure, your two audio files should now be one file with a smooth transition between them. No clicks, no pops, or other annoying noises.
