在客户端JavaScript中将WAV转换为任何压缩音频格式 [英] Converting WAV to any compressed audio format in client-side JavaScript
问题描述
我正在使用 getUserMedia（{audio：true}）; 的音频> Recorder.js ，然后将其导出为WAV文件，因为这是图书馆提供的唯一选项。
I am recording audio from getUserMedia({audio:true}); in the browser using Recorder.js and then exporting it as a WAV file because that's the only option the library provides.
1分20秒文件是14.1 MB大。我需要将音频上传到服务器，我需要快速完成。如何转换任何其他压缩格式的WAV音频以降低文件大小？
A 1 minute 20 seconds file is 14.1 MB large. I need to upload the audio to a server and I need to do it fast. How do I convert the WAV audio in any other compressed format to lower the file size?
我不介意转换为：
- MP3
- Opus
- WebM
- Ogg
- FLAC
- 您知道的任何其他格式
- MP3
- Opus
- WebM
- Ogg
- FLAC
- any other format you know of
如果现在没办法转换为这些格式中的任何一种，我怎样才能在客户端上压缩WAV文件？
If there is no way as of now to convert to any of these formats, how can I compress the WAV file on the client?
PS：我做了很多搜索找到任何在JS中转换WAV的东西，但什么也没找到。 libmp3lame.js 无法在Chrome中使用。
PS: I did a lot of searches to find anything that converts WAV in JS, but found nothing. libmp3lame.js isn't working in Chrome.
谢谢！
推荐答案
我制作了一个录音机，直接从浏览器中记录到mp3，结合了RecorderJS和libmp3lame.js
I've made an audio recorder that records to mp3 directly from the browser combining RecorderJS and libmp3lame.js
