Today we will learn a few more Audacity composing strategies, and then begin working to turn our scripts into complete drafts of audio essays.

Audacity Exercise

Start by quickly downloading, and then editing these files 

To get started, download this audio file, and then import it into a new Audacity project. Listen to the sound clip.

Next, perform the following operations on the clip; after each operation, 1) listen to the clip, 2) undo the operation (cmd/ctrl-z), 3) redo the operation using more intense settings, 4) listen to the clip, 5) undo the operation. Do all of these moves for:

  • Effect > High Pass Filter
  • Effect > Low Pass Filter
  • Effect > Change Pitch
  • Effect > Reverb
  • Effect > Compressor

Next, download this audio file, and add it to your project. Listen to the clip. Clean up the noise using these steps:

  • Select a small portion of the clip at the very end; select background noise but not the voice.
  • GO to Effect > Noise Reduction
  • In the dialog box that appears, choose Get Noise Profile; the box will close.
  • Now select the entire clip.
  • Go to Effect > Noise Reduction, and Select OK.
  • Listen to the clip. Experiment with the intensity of the noise removal. 

Now, try the same noise reduction operation on this clip.

Finally, save the project with a name like voice operations, paying attention to where you save the file.

When you have finished, you can get started on composing the draft of your audio essay, which is due on Friday.
