To access Edit menu, use the Edit tab at the top of the editing window:
The menu has following options:
UndoUse Undo to restore the recording to its state before the previous edit function. This is useful if you want to try an effect or to undo a mistake.
Note: You can undo up to 32 previous actions.
CutTo 'cut' is to delete the selected region but to keep a copy on the clipboard so it can be 'pasted' somewhere else. This is useful when moving parts of the audio around in the recording.
CopyUse Copy to make a copy of the selected region on the clipboard so you can paste it in another location. This is useful if you want to duplicate a part of the audio and insert it in another recording.
PastePaste can only be used after you have used the Cut or Copy functions (above).
The paste function replaces the current selected region (or inserts at the timeline marker if there is no selection). To replace a selection select "Edit / Paste". To insert click on the position and select "Edit / Paste".
DeleteThis is similar to the cut function, but a copy is not made on the clipboard.
Select AllUse Select All to select the entire recording before editing or applying an effect.
Insert silenceInsert a silence into the current position of the audio.
Auto TrimAuto Trim removes the silence at the beginning and the end of the selected region without you needing to find the exact position where recording starts.
This feature will not be useful in an environment with high background noise, as WavePad will be unable to differentiate between the background sounds and your voice.
To use this feature select "Edit / Trim / Auto Trim"
TrimTo 'trim' is to cut off the beginning and the end of the file so only the selected region remains. This is useful when you have just recorded a file but there is silence or noise before the start or after the end.
Select the part of the file you want to keep and then press trim.
Trim StartTo delete everything before the current position select "Edit / Trim / Trim Start"
Trim EndTo delete everything after the current position select "Edit / Trim / Trim End"
Making a SelectionMany of the functions apply to the selected region. To select a region, press the white button within waveform and drag.
To select the entire recording choose Select All from the Edit menu.
