In the setup() function, we create a new p5.AudioIn object to access the microphone, and we start receiving the microphone input with the start() function. The p5.sound library provides p5.AudioIn object that you can use to access and start using the microphone input. You can access the microphone of your computer within the p5 sketch using the p5.sound library. Using the same if-else-statement structure inside the draw() function, set the background to red if it audio is playing and to blue if the audio is not playing. If isPlaying() is true, pause() the audio, else, play() the audio. It uses the isPlaying() function to check if the sound file is already playing. If you set the audio file to play or loop inside the setup() function, it will begin to play / loop the audio file as soon as the audio file has finished loading and is ready to play.īelow is a simple example of using mousePressed() to play() and pause() audio file, and change the background accordingly.

The above functions that control the audio file need to be preceded by the name of the variable that you saved the loadSound() function to, followed by a dot(.) See the example code below: jump(time): Jumps the playback position to the specified time.currentTime(): Returns the current playback position in seconds.duration(): Returns the duration of the audio file in seconds.rate(r): Set the playback rate of audio file of specified r.Minimum of 0.0 (silence) and maximum of 1.0 (full volume). setVolume(vol): Sets the volume to the specified vol.isPlaying(): Returns true if audio file is currently playing.

Below are a selection of available functions that p5.sound library provides to control the audio file.

This ensures that the file is fully loaded to be playable and usable all the way through without buffering.Īll af the javascript functions that you already know to control the audio file exist within the p5.sound libary as well, such as, play() and pause(), in addition to many others.

It should also be called inside of the preload() function, to load the audio files before running setup(). loadSound() function should generally be saved to a variable, in which case the variable can be used to refer to the sound file inside the sketch. In order to use audio files, we use the loadSound() function. You can use an audio file inside of a p5 sketch for various uses, such as to do sound analysis (we will get to this later) and to trigger it at specified situations.
