More and more iOS devices offer iconic multimedia experiences to consumers, with vivid visuals, coupled with haptic interfaces. Regardless of the extensive range of capabilities on offer, as developers, experts focus on the apps’ visual design while neglecting the audio side of the user experience. HUAWEI audio kit is the current comprehensive audio framework created by designers as well as programmers for iOS. In the package is a broad mixture of tech-based apps with an Xcode Playground. That said, this is an audio kit tutorial user to train you about the audio kit. You will be taken through a little journey and framework via the sound synthesis history. Along the way, you will also garner extensive skills regarding the physics of early sound synthesizers and computer audio.
1. How to get started
Setting up an audio kit in the playground is currently pretty much easy. All you need to do is download and then unzip the starter playground.
The first step on this journey is not exciting, and you can always admit to this after going through the basic tutorials. There is basic plumbing needed if you are to use an audio kit in the playground.
- Open the audio kit file and click on the + button. It should be located at the bottom left-hand corner of the view.
- Choose the new playground option. You can name it Journey.
- Save it in the folder of playgrounds.
- The newly added playground should compile and then execute
It is important to note that you should use a project/build unless you want to experience an epic fail.
Once it has been built, care to run the playground once more. You should hear it emit seconds of a major beeping sound.
You can go ahead and use the current play and stop button located at the bottom left of the gadget in the Debug Area to stop the playground.
2. Understanding the physics of the sound
Humans beings have been creating music straight from physical objects via hitting and plucking and strumming in different ways. This has been happening for thousands of years.
Traditional instruments, like drums and guitars, have also been around for decades. The first recorded application of electronic instruments was utilized in making sound in 1874.
Since then, the oscillator has been used to synthesize sound. That is where your exploration should begin.
An oscillator creates periodic signals that often go on and on continuously, majorly indefinitely. Within the playground, sine waves are produced. The digital wave is processed by the audio kit, thereby directing the output to the computer’s speakers and headphones. This typically oscillates with the same sine waves.
The sound will be transmitted into your ears through compression waves. That is how you will hear the sharp sound, which could be annoying to some people.
