How to Change Your Voice Into Soundwaves

By Kevin Lee

When a voice makes a sound, it produces a soundwave. A computer can capture a soundwave, convert it into a digital waveform and display it on a graph. Audio technicians often manipulate voice soundwaves to create interesting vocal effects and correct musical pitch problems in the recording studio. Different voices produce different soundwaves. A baby's voice will not look the same as an opera singer's voice. You can see what your voice looks like by downloading an audio editing program and recording a few words.

Things You'll Need

  • Audio Editing Software
  • Microphone

Set up System

Step 1

Plug your microphone into your computer's "Mic In" slot.

Step 2

Click the Windows Start button and type mmsys.cpl in the Start menu.

Step 3

Press "Enter" to open the device properties window.

Step 4

Click "Recording" and place a checkmark by "Microphone" if no checkmark exists. Click "OK" to close the window.

Step 5

Download an audio editing program such as Wavepad, GoldWave or Blaze Media Pro. Find reviews of these products in the Resources section. Audacity is also a popular free audio editing program.

Step 6

Read the documentation that comes with your audio program. It will explain the program's user interface and functions.

Convert Voice

Step 1

Open the audio editing program and create a new audio file. You will usually perform this task by clicking "File" and then "New."

Step 2

Click the "Record" button. Find this button on the program's VCR-style control. This control has "Play", "Record" and "Stop" buttons similar to those found on an audio recorder.

Step 3

Speak into the microphone and record your voice. A soundwave graph of your voice will appear on-screen as you speak.

Step 4

Click "Stop" to stop recording and study the graph. Peaks and valleys on the graph represent variations in the volume of your voice during the recording process.

Step 5

Highlight an area of the graph using your mouse.

Step 6

Click "Edit" and then "Cut." This will delete the highlighted section of the soundwave. Verify this by clicking "Play."

Step 7

Highlight another area of the graph and locate the "Effects" button. Consult your program's help to find this button. Many programs place the effects button in the "Edit" menu located at the top of the screen.

Step 8

Select a special effect from the effects list and click "Play." You will hear the effect applied to the area of the waveform that you highlighted. This is how sound technicians manipulate audio waveforms.

Step 9

Click "Undo" at any time to undo any changes that you make to the soundwave.
