2. Creating Labels
To create the labels first go Edit > Labels > Add Label at Selection and check the keyboard shortcut (Ctrl+B in Windows) so that you don’t need to go back to the menu every time.
Now that you know the keyboard shortcut select a region in the spectrogram that you want to label (click and drag) and then use the shortcut to ‘Add Label at Selection’. A label track will appear and you can type the name for your label. You can repeat this process to add as many labels as needed!
Note: It helps to play the clip as you are labelling. You can use the ‘space bar’ to play and pause.
