将音频流保存到mp3文件（iOS） [英] Save audio stream to mp3 file (iOS)
问题描述
我有一个AVSpeechSynthesizer可以将文本转换为语音，但我遇到了问题。
I have an AVSpeechSynthesizer which converts text to speech, but i've encountered a problem.
我不知道如何保存它生成的音频文件到音乐文件，我非常希望能够做到这一点！
I don't know how to save the audio file that it generates to a music file, which I would quite like to be able to do!
所以这是我的问题，如何保存AVSpeechSynthesizer输出，如果这是不可能的，我可以使用AVFoundation，CoreMedia或其他公共API来捕获扬声器的输出，但在它出来之前？
So here's my question, how do you save the AVSpeechSynthesizer output and if this isn't possible, can I us AVFoundation, CoreMedia or other public API to capture the output of the speakers, but before it has come out?
谢谢！
推荐答案
不幸的是，没有公共API可用于捕获扬声器输出并查看AVSpeechSynthesizer和相关类的文档我看不到从中捕获任何音频。您可能需要查看第三方库以帮助解决此问题。
Unfortunately no, there is no public API available to capture the speaker output and looking over the docs for AVSpeechSynthesizer and related classes I don't see a way to capture any audio from it. You may want to look at 3rd party libraries to help with this.
