结合低录音音量与AVAudioSessionCategoryPlayAndRecord [英] Low recording volume in combination with AVAudioSessionCategoryPlayAndRecord

问题描述

当我设置：

[[AVAudioSession sharedInstance] setCategory:
    AVAudioSessionCategoryPlayAndRecord error:NULL];

...记录和播放工作正常，只是播放音量比我只想发挥同样的声音没有录音和设置PlayAndRecord降低60％左右。

…recording and playing works fine, just the playback volume is around 60% lower than when I would just play the same sound without recording and settings PlayAndRecord.

我需要得到大量峰（检查是否在MIC用户）吹了，我开始记录会话。但是，如果没有设置AVAudio..PlayandRecord，我不能在此期间播放任何声音。这就是我之所以执行这个命令。

I need to get high volume peaks (to check if a user blow in the mic) for that i started a recording session. But without settings AVAudio..PlayandRecord, i can not playback any sounds in the meantime. Thats the reason i implemented this command.

任何帮助吗？

推荐答案

有关每个人同样的问题，您重定向输出到扬声器：

For everyone with the same problem, redirect your output to the speaker:

[[AVAudioSession sharedInstance] setCategory:
    AVAudioSessionCategoryPlayAndRecord error:NULL];
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty(kAudioSessionProperty_OverrideAudioRoute,
    sizeof(audioRouteOverride), &audioRouteOverride);

这工作的。
