iPhone / iPad上的双声道录音：耳机+内置麦克风 [英] Two-channel recording on the iPhone/iPad: headset + built-in mic

问题描述

对于应用，我们需要从两个不同的音频源录制。一个麦克风是一个特殊的（喉咙）麦克风，它带有与麦克风使用的iPhone耳机相同的连接器。

For an app, we have a requirement to record from two different audio sources. One mic is a special (throat) mic and it comes with the same connector that the iPhone headset with mic uses.

在第二个频道，我们想记录环境声音和最好的事情是，如果我们可以在我们从喉部麦克风耳机录制的同时从iPhone的/ iPad的内置麦克风录制。

On a second channel, we would like to record the ambient sounds and the best thing would be if we could just record from the iPhone's/iPad's built-in mic at the same time as we record from the throat mic headset.

这有可能吗？任何其他提示？

Is there any way this is possible? Any other tips?

推荐答案

操作系统目前只允许应用程序一次连接到一个音频源路由。在iOS设备上录制2声道的唯一方法是使用Aple USB转Lightning接口（较旧型号的相机连接套件），带有标准USB立体声ADC或带有多个麦克风输入的音频混合面板。

The OS currently only allows an app to connect to one audio source route at a time. The only way to record 2-channels on a stock iOS device is by using an Aple USB to Lightning connector (Camera Connection kit on older models) with a standard USB stereo ADC or an audio mixing panel which has multiple mic inputs.
