详细描述

IMPORTANT There are 3 different ways of using CocosDenshion.

Depending on which you choose you will need to include different files and frameworks.

  • SimpleAudioEngine
  • This is recommended for basic audio requirements. If you just want to play some sound fx and some background music and have no interest in learning the lower level workings then this is the interface to use.

Requirements:

  • CDAudioManager
  • CDAudioManager is basically a thin wrapper around an AVAudioPlayer object used for playing background music and a CDSoundEngine object used for playing sound effects. It manages the audio session for you deals with audio session interruption. It is fairly low level and it is expected you have some understanding of the underlying technologies. For example, for many use cases regarding background music it is expected you will work directly with the backgroundMusic AVAudioPlayer which is exposed as a property.

Requirements:

  • CDSoundEngine
  • CDSoundEngine is a sound engine built upon OpenAL and derived from Apple's oalTouch example. It can playback up to 32 sounds simultaneously with control over pitch, pan and gain. It can be set up to handle audio session interruption automatically. You may decide to use CDSoundEngine directly instead of CDAudioManager or SimpleAudioEngine because you require OS 2.0 compatibility.

Requirements:

  • Firmware: OS 2.0 or greater
  • Files: CocosDenshion.*
  • Frameworks: OpenAL, AudioToolbox
