Open in Code Editor Copy Instructions Submit Solution

Since the exams are over, we will have a more open monthly challenge focusing on one of the site's extensions - audio

You will need to use the 4 currently supported audio procedures: PLAYSOUND, SETFREQUENCY, SETVOLUME and STOPSOUND - see the sound demos for examples

You can also use the additional Event keyword to perform/modify actions based on key presses, clicks, mouse position etc - see the event demos for examples

Some example projects are given below

• Morse code player
• White noise generator
• Simple synthesiser
• Echo effect
• Hearing test - find out the min and max frequency you can hear
• Sound guessing game - users here two sounds one after another and have to guess which is louder/higher frequency/correct wave type etc
• Duration guess - user has to accurately guess duration between two beeps
• Doppler effect demo
• Theremin simulator - mouse position effects volume/frequency
• Play a simple tune - e.g. ringtone, Mario theme tune, Crazy Frog, Never Gonna Give You Up etc
• Metronome
• Sound encoded - encode text as sound - e.g. frequencies depending on a character's ASCII code
• MIDI player - can use/modify JavaScript code in description here to convert MIDIs to procedure calls
• Piano - using the additional Event procedures, create a piano the user can play by pressing keys in their keyboard

...etc - there are many different examples you can think of
