复制音频直接在iPhone上的音频缓冲 [英] Copy Audio directly to audio buffer on iPhone

问题描述

有没有一种方法，以复制到AudioQueueBuffer直接？

我期待重新创建一个Android应用程序所使用android.AudioTrack的write（）函数直接写入到一个声音缓冲区。我所能做的使用AudioQueueBuffer类似的事情在iPhone上？

我要做的线沿线的东西：

  AudioQueueAllocateBuffer（mAudioQueueData.mQueue，数据大小，和放大器; mAudioQueueData.mBuffer）;
mAudioQueueData.mBuffer-＆GT; mAudioDataByteSize =数据大小;
的memcpy（mAudioQueueData.mBuffer-＆GT; mAudioData，soundData，数据大小）;
AudioQueueStart（mAudioQueueData.mQueue，NULL）;
 

解决方案

是的，它是可能的，你找什么叫RemoteIO。这是有点难以成立第一个，但给你的音频缓冲区的直接控制，是iPhone上的最低级别的音频API。

Is there a way to copy to an AudioQueueBuffer directly?

I am looking to re-create an Android app that used android.AudioTrack's write() function to write directly to a sound buffer. Can I do a similar thing using the AudioQueueBuffer on the iPhone?

I was going to do something along the lines of:

AudioQueueAllocateBuffer( mAudioQueueData.mQueue, dataSize, &mAudioQueueData.mBuffer);
mAudioQueueData.mBuffer->mAudioDataByteSize = dataSize;
memcpy(mAudioQueueData.mBuffer->mAudioData, soundData, dataSize);
AudioQueueStart(mAudioQueueData.mQueue, NULL);

解决方案

Yes it's possible, what your looking for is called RemoteIO. It's kinda hard to set up first, but gives you direct control of the audio buffer and is the lowest-level audio API on the iPhone.
