EDITING
DIGITAL AUDIO CLIPS in AUDACITY
Here are some fundamental edits that most clips need done:


When you first recording into Audacity consider
  • If the clip is in stereo, you may want to simplify it to MONO

TRIM
Trimming removes "blank" audio at the beginning and end of your audio clip
  1. Use the SELECTION tool
  2. Highlight the "blank" portion at the beginning
  3. Hit your DELETE key
  4. Repeat the process to trim the blank portion at the END of your clip

NORMALIZE
This will adjust the relative levels of your waveform to peak at -1.0 Db
  • EFFECT | NORMALIZE
*

AMPLIFY (Although NORMALIZE is better)
Although a good setup shouldn't require too much amplification, most of the time, amplifying will optimize your audio if its peak is less than -12db
  • With the selection tool, click anywhere in the clip
  • Use CTRL A to select ALL
  • Use EFFECT | AMPLIFY and hit OK
    • Set the limit to JUST under 0 Db - say -0.1
    • A value will be calculated for you to optimize the clip for you

FADE
To minimize the presence of leading or trailing noise, it may be necessary to FADE your clip in or out
  1. Use the selection tool to select just the trailing end of your clip (see picture)
  2. Use EFFECT | FADE OUT and click OK
  3. Repeat if necessary to FADE IN the beginning of your clip

ENVELOPE
The Envelope ToolAudacity_Envelopetool.png
Allows you to control the volume of a track at various points in time, and with smooth fades between those points.

SPLIT CLIP
(Ctrl-I)
Splitting the clip allows you to turn the recording into individual segments that can then be Time shifted or processed seperately

TIME SHIFT
You can move a segment forward or backward using the tool

ECHO
  • EFFECTS - ECHO
    • Try a value of 0.2 and 0.2 to start out with; it gives you the effect of a nightclub or small stage
  • DELAY TIME - 0 is no delay; larger make the "room" seem larger
  • DECAY FACTOR - 0 is no echo; larger increases the volume and repetitions of the echo


TIPS:
  • Highlight a chunk of dialogue and hit the PLAY button to preview it
  • Delete the chunks of dialogue that is flawed
  • Amplify chunks of dialogue that are too low in levels
  • Trim and fade chunks to remove leading and trailing noise

SELECT - SAVE YOUR DIALOGUEAudacity04.jpg
  • Highlight the first bit of dialogue you’d like to save. Preview it by click the PLAY button
  • Use FILE | EXPORT SELECTION as WAV to save that first clip. Repeat the process for any remaining audio clips.
  • Record all your dialoque at once, but save them into seperate files.
  • NOTE: Be careful NOT to simply use [CTRL-S] or SAVE PROJECT - that creates a complex series of files in Audacity's project storage format. It will NOT create any useful files for you to import into any other program.

If you've followed the instructions properly, your voiceover work is now in WAV format and ready to be imported into Premiere or Flash.
