Getting Started: Playing and Editing a Soundfile

 

The Fast Edit Main Screen

Figure 1-1 Fast Edit Startup Window
  1. When Fast Edit is first opened from Windows?, an empty window is displayed, as shown in Figure 1-1. The main window consists of a title bar, the menu bar, and two separate sound display windows. Each sound display window has a waveform display area, bordered above and below by colored bars, and a set of buttons and controls at the bottom. Soundfiles that you open are displayed in the bottom window, the Read Only window. The top window is called the Modify window; this is where most editing operations are performed. In general, new soundfiles in the Modify window are to be constructed using portions of soundfiles from the Read Only window so that the original recordings are not altered.

Right now the Read Only window's upper bar is red, indicating that it is the active window; that is, operations permitted in either window will now act on the Read Only window.

Step 1: Copy a portion of a voice recording for editing

Open the soundfile "voice.wav"

After a very brief pause, the Read Only window will display a waveform representing the data in the file, as shown in Figure 1-3. The name of the file is now displayed on the left side of the Read Only window's upper bar. On the right hand side is the amplitude scale, which is presently set at zero decibels.

A narrow vertical line is at the center of the waveform. This is the Edit Cursor which points to your location in the soundfile. The scroll bar at the bottom of the Read Only window confirms that you are in the center of the soundfile, as does the time display at the lower right.

Figure 1-3 Displaying "voice.wav"

Play the soundfile

A vertical bar called the play cursor moves across the display as the soundfile plays.

Play the file again and interrupt the playback.

Type the Enter key during playback.

Play the soundfile again, pausing and unpausing the playback.

Type the space bar repeatedly during playback.

Try this again but stop the playback while it is paused.

Type the Enter key while playback is paused.

When playback is stopped in this way, the Edit Cursor is moved to the location at which playback was paused. By using pause and stop during playback, you can accurately locate points of interest in the soundfile.

Select a region

The "voice.wav" file says,

"...production work was never so easy!....harumph(throat clear)....Fast Edit...by Minnetonka Audio Software...Fast Edit..."

Our goal is to edit the voice so that it says

"Fast Edit...by Minnetonka Audio Software....production work was never so easy!"

We have one extra "Fast Edit" at the end of the soundfile. You will eliminate the extra phrase by copying the entire window except for the extra phrase.

The first step is to move to the beginning of the soundfile.

It may be difficult to see the Edit Cursor in this location, but the location of the scroll bar box and the time display reading verify that you are there.

Next, Select a portion of the soundfile, which marks a portion of the soundfile for special treatment by some function or operation.

The button marked `S' in the lower left-hand part of the Read Only window is now highlighted, indicating that Selection is enabled. When Selection is enabled, an anchor point is dropped at the current Edit Cursor location, and any movement of the Edit Cursor will extend the Selection, highlighting the portion between the anchor point and the Edit Cursor.

Move the cursor to extend the Selection to the space before the unwanted phrase; the break is approximately 6.1 seconds into the file.

The appearance of the Selection will be as shown in Figure 1-4.

Figure 1-4 Selected Region in "voice.wav"

Play the Selection to ensure that the correct portion is Selected.

If you have Selected the region correctly, it will say,

"...production work was never so easy!....harumph(throat clear)....Fast Edit...by Minnetonka Audio Software..."

Once the correct Selection has been made, you can duplicate it in the Modify window through the use of the copy and Paste operations.

First, copy the Selected region.

The sound is now copied. Selection remains enabled in the Read Only window.

The "Clip 1" in the row of buttons labeled "Clip 1", "Clip 2", "Clip 3", "Clip 4", and "Windows" now has a red square outlined in yellow. The red square indicates that our Selected region is now copied into Clipboard 1.

Now you are ready to Paste the sound into the Modify window.

Several things have now occurred as a result of the Paste, as illustrated in Figure 1-5. First, the Modify window is now the active window, as indicated by the red upper bar. The word "Modified" appears in the bar to show that the contents of the window have been changed. The amplitude scale is in accordance with the sound that was Pasted. Notice that there is not yet a file name associated with the soundfile in the Modify window.

Figure 1-5 Display Windows Following the Paste Operation

The most important thing that has happened is that the sound that you have Selected and copied is now in the Modify window. An Edit Cursor now appears in this window, in the middle of the Pasted portion of sound.

Step 2: Select and examine a portion of the voice soundfile

Play the sound in the Modify window.

Sounds great, except that the speaker "harrumphed" during his commentary. Next you will delete this part of the recording.

Select the "harrumph," which is approximately located from 2.14 seconds to 3.0 seconds in the soundfile. The correct Selection is shown in Figure 1-6.

Figure 1-6 "Harrumph" Selection

To confirm that the correct Selection has been made, play the Selection.

When this audible comparison is not enough to confirm that the correct region is Selected, you can examine the Selection in more detail by zooming in and looking at a smaller range of samples.

For now, zoom in to view the Selection you have made.

This produces a view of the Selection with a small amount of unSelected data on either side, as shown in Figure 1-7.

Figure 1-7 Viewing the "harrumph" Selection.

With the zoomed-in display, it is much easier to see the "harrumph" in detail. You can use the mouse to adjust the position of both edges of the Selected region.

When the "harrumph" is accurately highlighted, you can zoom back out to the full voice soundfile.

Step 3: Perform edits on the voice recording

Now delete the "harrumph."

Play the soundfile to hear the result. It should now say,

"...production work was never so easy!....Fast Edit...by Minnetonka Audio Software..."

To complete our editing of the voice, we want to rearrange the order of the two phrases from

"...production work was never so easy!....Fast Edit...by Minnetonka Audio Software..."

to

"Fast Edit...by Minnetonka Audio Software......production work was never so easy!"

To do this, you will Cut the second phrase off the end of the soundfile, and Paste it onto the beginning of the soundfile.

Figure 1-8 Selection of Second Phrase

Play the second phrase before Selecting it.

Now Select the second phrase in the soundfile. The Selection is illustrated in Figure 1-8.

Verify that the Selection is accurate by playing the Selected region. It should say

"Fast Edit...by Minnetonka Audio Software..."

When you are satisfied with the Selection, Cut it onto the clipboard.

Play the top window to hear the result. It should now say

"...production work was never so easy!"

Now Paste the contents of the clipboard at the beginning of the file.

Play the soundfile to hear the result. The two phrases are now reversed to say

"Fast Edit...by Minnetonka Audio Software......production work was never so easy!"

Now that the voice has been edited correctly, you will save it onto the hard drive.

A dialog box will appear (Figure 1-9).

Figure 1-9 The Save As Dialog Box

The voice in the Modify window will be saved on the disk as a soundfile named "goodvoic.wav." You can now verify that the sound was saved.

You will see that "goodvoice.wav" now appears on the list of soundfiles on your hard disk.

Good job! You have completed this tutorial, and can now exit Fast Edit.

The next tutorial includes methods for doing Fades and Mixes, using the soundfile you just made.
