Chapter One: FundamentalsThis chapter will show you how to start learning about Web audio APIs, which browsers support audio APIs, how to detect if an audio API is available, what an audio graph is, what an
The Web Audio API provides a simple and powerful mechanism for controlling the audio content of a Web application. It allows you to develop complex mixes, sound effects, panning and more.You can take a look at the MDN article "Application of

Microsoft has made a lot of interfaces for programming with DirectX brothers. We can see below ildasm that there is only one class named filgraphmanagerclass. In fact, I have read it carefully, there are not many large functions. DirectX is divided into four layers in abstraction,
Hardware/network layer: multimedia devices, including Graphics accelerators, sound cards, input devices, and network communication devices;
DirectX base layer: provides basic multimedia services for images, sounds, and

This depends on the level at which you want to provide direct support: If you want to support enhanced desktop software multiplexing, use the PulseAudio volume control API. If you want to support the hardware mixer, use the ALSA mixer API.

Audio is a great way to make the multimedia experience very compelling. If you've ever tried to watch a movie with a sound shutdown, you're likely to have noticed that.
The game is no exception! The memories of my favorite video games include music and harmony. Today, 20 years later, most of the time, when playing my favorite game, I still can't banish the music of Zelda and the Dark soundtrack of Matt's Rikunto from my mind. The same app

Development Kit (SDK). This SDK is an API and development toolset that can be used by object-oriented C developers to create native iOS applications. While much of the iOS SDK is not directly available to flash developers, its performance analysis and diagnostic tools can still be used to debug applications. In addition, it is helpful to know what is included in the SDK, especially when reading Apple company reference materials related to iOS applica
