For each sound, listen to Versions A to E. Each has a sound alone button and an as in … button. Choose the one you like best, or None if none are good. The versions are in a different order for each sound. Sounds marked HARD SOUND are the 21 tricky ones. Each version shows who made it. Tap Adjust to change speed or volume; the settings are kept with your choice. There is no need to press save: every choice saves by itself (see the top of the screen).
