Fixing, sweetening, and creating soundtracks in Soundbooth

full-blown:  possessing or exhibiting all the usual or necessary features or symptoms  


Cleaning up noisy audio
1. Open 14-6.prproj.
2. Double-click audio problem.wav (Remember to double-click the icon before the title of the file.) to open it in the Source Monitor.
3. Open audio problems fixed.wav in the Source Monitor, and listen to it. The hum and the cell phone were removed.
4. Drag audio problems.wav to the Audio 1 track on the Timeline.
5. Right-click the audio problems clip on the Timeline and choose Edit in Adobe Soundbbth > Render And Replace from the context menu. 
6. Soundbooth displays 2 views of your audio file: the common waveform view showing audio amplitudes and a colorful spectral display view showing audio frequencies.
7. Play the file again to hear the problems, the hum and the cell phone ringing.
I think the hum here is bearable.
8. To remove the 60 Hz hum, click the Effects tab in the left-center panel. Click the Stereo Rack Preset pop-up menu, and choose Fix: Remove 60 Cycle Hum.
9. Play the file again.
I think the difference is slight.
10. To permanently apply this changes, click the Apply to File button at the bottom of the Effects Rack.
11. To remove the cell phone sound, you need to use the spectral display. It is in the spectral display as short horizontal dashes between 2 kHz and 3 kHz.
12. Position CTI over the 1st cell phone ring, and zoom in by pressing = on the keyboard of + on the numeric keypad.
13. Select the Rectangular Marquee tool, and select the cell phone ring. When you are finished, the selection appears as an opaque box around the cell phone ring with a dB adjustment tool floating above it.
14. Adjust the selection to -34 dB. This reduces the frequencies you selected by negative 23dB.
15. Play the clip. It sounds better.
16. Save the changes to the clip by choosing File > Save. Switch back to Premiere, and notice that the audio file on the Timeline has been updated with the changes.
The ring is still there???
