Problem: Create a reactive soundscape – Uncover


Convey on the noise: It is time for a sound design problem! We’re inviting you to experiment with inventive methods to govern sound on iPhone and iPad utilizing its myriad sensors, inputs, and variable states. (Consider typing on the iOS keyboard — the place the important thing sounds get steadily quieter the quicker you sort.) Discover over 70 audio information from Apple sound designers and create a sonic expertise of your very personal!

We additionally welcome you to go to the Design Examine Corridor in the course of the day to collaborate on this problem! Ask questions, join with different builders and designers, and share your creations.

Start the problem

First, obtain our problem sound library. In it, you’ll discover greater than 70 audio information from Apple sound designers, together with:

  • ChromaticScale: Consists of 13 one-shot audio information that make up the musical notes of a chromatic scale.
  • InstrumentalLoops: 155 bpm sound information that may be seamlessly looped, mixed, and layered.
  • OneShots: One-shot sounds that can be utilized as alerts, notifications, and extra.
  • Samples: Sustaining samples of 1 word every.
  • SineLoops: Looping pad sounds fashioned with sine waves. Very like the InstrumentalLoops, they are often layered, added, and eliminated.
  • SwitchesAndTaps: Consumer-interface sounds.
  • Misc: A group of enjoyable and provoking sounds.

Obtain sounds for the problem

Utilizing any of those connected sounds and AVAudioEngine, we invite you to create a sonic on-device expertise that adjustments based mostly on sensor enter or gadget state. Take into account components like contact enter, movement and acceleration sensing, GPS or compass place, ambient mild sensing, and digital camera or microphone enter.

  • May you employ contact gestures to morph a looping sound’s frequency or amplitude?
  • May you employ a tool’s movement sensor to set off a sound — or use the accelerometer to alter the relative volumes of a number of sounds triggered directly?
  • May you employ GPS to alter a notification sound based mostly in your distance from house?
  • In case your app detected a clap by the microphone enter, may it set off a sound? May you employ the amplitude of that microphone enter to find out which sound performs?
  • Are there different variables that could possibly be used to have an effect on audio playback — time of day, climate, inventory costs?
  • How may these concepts impression your current tasks?
