问题描述

我使用的OpenAL在特定的时间间隔播放声音样本，我想这个出口到文件（不论是咖啡馆或AAC或其他）。我怎么能做到这一点与OpenAL的，无需通过音箱/耳机实时打我的样品？

I'm using openAL to play sound samples at specific intervals and I want to export this to file (be it caf or aac or whatever). How can I do this with OpenAL without having my samples played in real time through the speakers/headphones?

推荐答案

如果你在谈论导出乐谱作为一个完整的音频片，没有什么在OpenAL的，会做这样的事情。

If you're talking about exporting your musical score as a complete audio piece, there's nothing in OpenAL that will do such a thing.

我能想到的唯一的办法是使用单位的音频播放，并用它离线模式转储到一个文件中。

The only way I can think of would be to use Audio Units for playback, and use it offline mode to dump to a file.
