Since VFEdit^® can display a waveforms at very high resolutions (1 sample per graph point) and very low resolutions (32,000 samples per graph point), you can use the View Menu to change the display resolution.

VFEdit lets you see your file as you edit with a full screen waveform display. Zoom In to edit at single sample precision, Zoom Out to any user-defined resolution. Zoom to Fit your current selection for full screen control.

The View Resolution parameters affect the graphical representation of the audio data. View Resolution changes the amount of information used to compute the waveform display.

The View Resolution Low menu command lets you change the current view resolution to 2,000 milliseconds (2 seconds) per major division. This means, for example, that a file digitized at 6,000 samples per second will be displayed such that 12,000 data samples appear within one major division. By similar calculations, this setting will let you view 40 seconds of voice data at any one time.

Use this setting for a coarse overview of the file of interest, and for the overview and comparison of several files.

The View Resolution Medium menu command lets you change the current view resolution to 500 milliseconds (.5 seconds) per major division. This means, for example, that a file digitized at 6,000 samples per second will be displayed such that 3,000 data samples appear within one major division. By similar calculations, this setting will let you view 10 seconds of voice data at any one time.

Use this setting for editing phrases. This is the default setting when VFEdit is first started. This is the recommended scale for general work.

The View Resolution High menu command lets you change the current view resolution to 100 milliseconds (.1 seconds) per major division. This means, for example, that a file digitized at 6,000 samples per second will be displayed such that 600 data samples appear within one major division. By similar calculations, this setting will let you view 2 second of voice data at any one time.

Use this setting for editing specific words, and for working with very small increments of file.

When you change View Resolution parameters, VFEdit automatically checks to ensure that the values are within range. If the values are outside of range, VFEdit will issue a warning "beep" and reset the parameters to their previous values.

The View Zoom In menu command lets you double the current view resolution, thereby seeing less of the current file, but at greater resolution. View Zoom In is useful for quickly increasing the view resolution for more precise editing. View Zoom In attempts to keep the current center view point in the middle of the screen. If, however, you are near the end of the file, this point will shift left to accomodate the blank right edge of waveform.

The View Zoom Out menu command lets you half the current view resolution, thereby seeing more of the current file, but at lower resolution. View Zoom Out is useful for quickly decreasing the view resolution for coarser overview editing. View Zoom Out attempts to keep the current center view point in the middle of the screen. If, however, you are near the end of the file, this point will shift right due to the shortened apparent length of the waveform.

The View Zoom to Fit menu command tells VFEdit to automatically adjust the view resolution to display an entire selection segment. View Zoom to Fit is useful for quickly adjusting the display for maximum resolution while allowing you to see all of your current segment of interest.

View Zoom to Fit attempts to fill the whole work area with the selected segment. If, however, you are near the end of the file or are already near a 1:1 view resolution, VFEdit may not be able to completely fill the screen.

The View Scroll menu items lets you maneuver around in your current file. View Scroll lets you display the part of the file that you have chosen, either the start or the end of the file, or the left or right from your current position. The triangular "At Position" insertion marker is not moved with these commands.

The View Scroll To menu command lets you quickly move to a specified position in the file. View Scroll To gives you precision that you don't have with the cursor alone. This command moves both the displayed portion of the sound file as well as the triangular "At Position" insertion marker. View Scroll To is useful if you need to move rapidly between arbitrary locations in a file.

After selecting View Scroll To you will be presented with a dialog box that enables you to specify the new file position (in seconds). VFEdit will then center (if possible) this new location on the screen.

Use View Tool Bar command to toggle the top level toolbar on or off, or select View Status Line to toggle the bottom level status line on or off. These commands are useful if you want to maximize the amount of work space on your screen display.

The View Configure menu lets you change view parameters. After selecting View Configure, you will be presented with a dialog box that enables you to adjust the default resolution settings to fit your particular editing needs.

View resolution is specified as milliseconds (1/1000^th of a second) per major division. The waveform display contains 20 major divisions, each of which is subdivided into 5 minor divisions. At the default medium resolution you will be able to see 10 seconds of voice data at any one time. Larger resolution values let you see greater periods of time per screen; smaller values let you see more detail.
