Web Audio API - 记录到MP3？ [英] Web Audio API - record to MP3?

问题描述

我在问，因为我无法在任何地方找到答案。
我已成功实施 RecorderJS ，以便在JS中录制麦克风输入。但是，录制的文件是WAV，导致大文件。我正在寻找一种方法用JS直接录制到MP3，或者以某种方式将这些位编码为MP3而不是WAV。

I am asking because I couldn't find the answer anywhere. I have successfully implemented RecorderJS in order to record microphone input in JS. However, the recorded file is WAV which results in large files. I am looking for a way to record with JS directly to MP3, or encode the bits somehow to MP3 instead of WAV.

如何做到这一点？有没有可以做到的Web Audio API功能或某种JS MP3编码器？

How can it be done? Is there a Web Audio API function that can do that or JS MP3 encoder of some sort?

推荐答案

我见过的唯一的Javascript MP3编码器是 https://github.com/akrennmair/libmp3lame-js ，这是一个使用emscripten的端口。它应该很慢，而且我从来没有使用它。

The only Javascript MP3 encoder I've seen is https://github.com/akrennmair/libmp3lame-js, which is a port using emscripten. It's supposed to be slow, and I've never used it.

我不知道任何原生编写的Javascript MP3编码器，编码不包括在内Web Audio API。

I don't know of any natively-written Javascript MP3 encoders, and encoding is not covered by the Web Audio API.
