Fade In and Fade Out

[Craig Maier]

Fade-In

Fade-In does what the name implies when applied to the beginning of a .wav file. You can choose between linear or logarithmic envelopes, and you can also choose the time period for the Fade-In by selecting the portion of the .wav file over which you desire the Fade-In to occur. Lastly, you can choose the "start level" for Fade-In as well as the "stop level." ("Level" is the start and stop loudness for the Fade-In.) Fade-In operates on the selected file (which can be the Source or Destination file).
Fade-In Procedure (Tutorial)

1. Listen to the beginning portion of your .wav file and determine the position near the beginning of your .wav file during which you desire to produce a "Fade-In" effect.
2. At the beginning of the sector of the .wav file that you desire to apply the "Fade-In" effect, click down on the left mouse button and keep holding it down as you drag the timing bar (using the mouse) towards the right of the workspace.
3. Stop dragging the mouse when you arrive at a location just prior to the actual beginning of the signal portion of the .wav file.
4. Release the left mouse button. You will notice that the section between the two timing bars will remain highlighted in yellow. This is the sector during which you have chosen to apply a "Fade-In" effect.
5. You can click the right mouse button to hear if you have chosen the correct portion of the .wav file to apply the "Fade-In."
6. Click on the Edit Menu function.
7. Under the Edit menu, Click on “Fade-In”.
8. Choose the type of Fade that you prefer; either Linear or Logarithmic.
9. Set the "Start Level" slider to zero gain (all the way down). The default setting for this control is zero gain.
10. Set the "Stop Level" slider to 0 dB (unity gain). The default setting for this control is unity gain.
11. Click on OK. The "Fade-In" function will be performed on the chosen portion of the .wav file.

Note: After a Fade-In has been performed; there may be a sector of your .wav file containing some noise at the very beginning just prior to the start of the Fade-In. This can be eliminated with the Mute function.
Fade-Out

Fade-out also does what the name implies. It contains all of the features outlined in the "Fade-In" description except that it normally works near the end of the file. Fade-Out runs under the Edit menu, and unlike the various Filter functions, operates directly on the selected file (which can be the Source or Destination file).
Fade-Out Procedure (Tutorial)

1. Determine the position near the end of your .wav file where you desire to apply the "Fade-Out" effect.
2. At the beginning of the sector of the .wav file where you desire to apply the "Fade-Out" effect, click down on the left mouse button and keep holding it down as you drag the timing bar (with the mouse) towards the right of the workspace.
3. Stop dragging the mouse when you arrive at a location in the file where you want total silence to occur.
4. Release the left mouse button. You will notice that the sector between the two timing bars will remain highlighted in yellow. This is the sector during which you have chosen to apply the "Fade-Out" effect.
5. You can click the right mouse button to hear if you have chosen the correct portion of the .wav file to apply the "Fade-Out."
6. Click on the Edit Menu function.
7. Under the Edit menu, Click on Fade-Out - - -
8. Choose the type of "Fade-Out" which you prefer, either Linear or Logarithmic.
9. Set the "Start Level" slider to 0 dB (unity gain). Unity gain is the default setting for this control.
10. Set the "Stop Level" slider to the zero gain position (all the way down). Zero gain is the default setting for this control.
11. Click on OK. The "Fade-Out" function will be performed on the chosen portion of the .wav file.

Note: After a "Fade-Out" has been performed, there may be a sector of noise after the "fade-out" and the end of your .wav file. This can be eliminated with the Mute function.
