Apply Special Effects

If you just want to apply a special effect like increasing the volume of a sound file (or apply any other effect on a sound file):

Start Adobe Audition; you will then have an empty session. Click the first track. Right-click and select Insert-Audio; select the file you want to process. After loading (it may take a few seconds) double click on the sound. This will take you from the multitrack view to the edit view. If you want to apply the effect only on a part of the file, select that part with the mouse, just as you would select text in a word processor. On the left side of the screen, there is a treeview; click on the Effects tab. Then double click on the effect you want to apply. For changing the volume, you want to use Amplitude - Amplify/Fade. A window will then appear. For volume increase, try to set +3db; a positive value will increase the sound volume; a negative one will decrease the sound volume. To save your work, use File-Save As.

Normalising sounds. Normalization is an editing function that adjusts the highest peak amplitude of a waveform to a certain percentage, thereby raising or lowering all other peaks accordingly. This technique is most useful when you author a CD or master a collection of songs and each of the intended CD tracks vary in overall peak amplitude. Normalizing a collection of tracks applies a consistency that is implied when playing CD’s on consumer equipment (for example, stand-alone CD or DVD players).
