Soundwave is an application used mostly in earlier SwitchBoard firmwares for playing audio files. Upon opening the app, you will be presented with a green box showing you your available audio to play. It is presumed that one needs to put their desired audio file into a specific directory in the filesystem in order to play it with Soundwave (the directory is currently unknown.) Below, you'll also be given the option to play audio out of either the speaker or reciever, as well as stop the audio you're currently playing. The only way to exit the app is by hard resetting.
