This app is experimental and considered to be work-in-progress. It is expected to remain work-in-progress for many years as new features are required while users design new experiments, new discoveries are made, and as new technical capabilities become available from device manufacturers. Despite this work-in-progress nature, this app still has some unique advantages, such as being free, available on inexpensive off-the-shelf devices, designed to be used in water near dolphins, with a customizable recognition algorithm and expandable features.
This application is for conducting two-way communication experiments using whistles. Using this app, you may emit one or more whistles and listen to the response by dolphins (the app will show you the sound and try to recognize them for you), then you may reply with your own whistles. Dolphins may also command the device.
Available only on Android.
The main screen works like a chat or text messaging application, and it emits and recognizes whistles. When the app recognizes a whistle that it already has in its lexicon, it surrounds its name or number by ((( ))), such as ((( hello ))) or ((( 147 ))) and ((( ^123 ))). When the app does not recognize a sound as a known whistle, it gives it a number and displays that number without the ((( ))), such as ^123. To emit one or more whistles, you type their names or numbers in the edit text box and select the Emit button. After an emission you may repeat it by selecting the Repeat button.
Sample built-in whistles are hello, hello-world, hi, bye, yes, no, m, caret, u, v, w, and wv. You can make your own whistles with a built-in graphical editor.
A spectrogram behind the chat text lets you see the energy of the surrounding sounds in real time.
This version has a database which lets you save sessions data.
Also, using two devices with this app, two or more people can play a game where someone is the dolphin and the other is the researcher. Only whistles are allowed for sound. You can use props to identify by whistles and requests actions by whistles. Try to communicate with another person just by using whistles and this will give you an idea of the difficulties in communicating with dolphins.
Main Features: - Emit whistles selected by the user - Acquire whistles from the surrounding sounds and keep them in a lexicon - Recognize whistles; when a whistle is recognized it is identified to the user - Shows the energy and frequencies of surrounding sounds in a real-time spectrogram - Shows some of the events of the workings of the app - Pause and restart the spectrogram in order to observe interesting sound energy patterns - Perform a self-test where the app can test itself by attempting to recognize emitted whistles - Hide the chat text in order to better see the spectrogram - Edit whistles with a graphical editor - Commands entered by the human user - Commands in the form of whistles, to be used by dolphins or a second device - Database to save, export, analyse, and share whistles and other data.
Menu Options: - Show all whistles in the lexicon, cetacean-made and man-made whistles - Show the main settings - Show all available commands - Show the database status - Show a User Guide - Write an email to the developer - Show other apps in the Play store by Simplecode - Show an About text
