音频会话类别路由覆盖

指定是否应覆盖PlayAndRecord类别的默认音频路由.

Specifies whether the default audio route for the PlayAndRecord category should be overridden.

enum {
   kAudioSessionOverrideAudioRoute_None    = 0,
   kAudioSessionOverrideAudioRoute_Speaker = 'spkr'
};

常量

kAudioSessionOverrideAudioRoute_None

为 kAudioSessionCategory_PlayAndRecord 类别指定输出音频应到达接收器.这是该类别的默认输出音频路由.

Specifies, for the kAudioSessionCategory_PlayAndRecord category, that output audio should go to the receiver. This is the default output audio route for this category.

kAudioSessionOverrideAudioRoute_Speaker

为 kAudioSessionCategory_PlayAndRecord 类别指定输出音频应传递给扬声器，而不是接收器.

Specifies, for the kAudioSessionCategory_PlayAndRecord category, that output audio should go to the speaker, not the receiver.

讨论 kAudioSessionCategory_PlayAndRecord 类别支持同时输入和输出.您可以使用此类别，例如，为进入iPhone麦克风的音频添加效果.默认情况下，此类别的输出音频会传递到接收器，即您在通话时将其放在耳边的扬声器. kAudioSessionOverrideAudioRoute_Speaker 常量使您可以将输出音频定向到位于手机底部的扬声器.

Discussion The kAudioSessionCategory_PlayAndRecord category supports simultaneous input and output. You could use this category, for example, to add an effect to audio coming into the iPhone’s microphone. By default, output audio for this category goes to the receiver—the speaker you hold to your ear when on a phone call. The kAudioSessionOverrideAudioRoute_Speaker constant lets you direct the output audio to the speaker situated at the bottom of the phone.
