Zooming, selecting, editing

In the bottom left corner you will find a number of buttons for zooming. ‘in’ and ‘out’ should be self-explanatory. ‘sel’ zooms in so that your selection fills the entire window. ‘all’ shows the whole recording and ‘bak’ returns to the previous zoom window.
Selecting is easy. Just click (in the spectrogram) where you want your selection to start, and hold the key while dragging to where you want the selection to end. See the ‘Select’ menu for options like moving the cursor to a precisely specified time. One special command might be of interest, especially if you want to edit your sounds. ‘Move start (or end) of selection to nearest zero crossing’ can be used to make sure there is no unwanted noise when you copy-paste bits of sound.
Editing is straightforward as well. Once you have made a selection click on ‘Edit’ and ‘Cut’ (shortcut: CTRL + X) to cut it. Placing the cursor somewhere and clicking ‘Edit’, ‘Paste after selection’ inserts a sound from the clipboard at the current location. Finally, selected bits can be saved as separate sounds via ‘File’ and ‘Save selected sound as. . . ’.
