Sweetening sound with audio effects

1. Open 14-1.prproj
2. Drag Ad Coiches Mono.wav to the Audio 1 track
3. Open the Audio Effects > Mono folder in the Effect panel.
4. Drag Bass to the Ad Cilches clip > open the Effect Controls panel > click the  disclosure triangle of Bass and that of Boost to expand the parameters.
5. Play the clip, and then move the Bass Boost slider left and right. This increases or decreases bass.
Going left decreases bass and going right increases bass.
6. Delete Bass from the Effect Controls panel and add Delay.
Consult Help for more audio effects.
7. Play the clip and move the sliders to experiment with the effect.
8. Delete Delay and add PitchShifter to the Effect Controls panel.
You can tell an audio effect has presets by the tiny triangle next to what would normally be the Reset button and addition of a rectangular Reset button.
This sentence might tell the slight difference of interface between video effect and audio effect.
9. Try some of the presets, and note their values below the knobs in the Effect Controls panel.
10. Use the Individual Parameters sliders, and add keyframes at the beginning and end of a few phrases( a short musical thought typically two to four measures long closing with a cadence).
Use wildly different Pitch settings from -12 to +12 semitone steps (2 steps equals a second in musical parlance -- from C to D, for example), and switch Formant Preserve on and off.
11. Delete Ad Cliches from the sequence and replace it with Music Mono.wav.
12. Drag Treble to that clip and increase its parameter.
This guitar clip lends itself to a tremble boost.
13. Delete Treble, drag Reverb to the Effect Controls panel, and open Reverb's Custom Setup.
14. Play the clip, and drag the 3 white handles in the display to change the character of the reverb.
