录制从AVPlayer流式传输的音频 [英] Record audio streamed from AVPlayer

问题描述

我正在尝试录制/捕获通过 AVPlayer 进行流式传输的音频。 AVAudioRecorder 只能从麦克风录制，如果通过扬声器播放音频可能会有效（虽然质量会受到影响），但如果插入耳机，它肯定无法工作。

I'm trying to record/capture audio that's being streamed via an AVPlayer. The AVAudioRecorder only records from the microphone which may work if the audio is played via speakerphone (although quality will suffer) but it'll definitely not work if the headphones are plugged in.

我到处寻找解决方案，但仍未找到适用于我的解决方案。我需要抓住音频缓冲区吗？还有另一种方法来捕捉正在播放的内容吗？

I've looked everywhere for a solution but still haven't found a solution that'll work for me. Would I need to grab the audio buffer? Is there another way to capture what's being played?
