与 Sox/Audacity 一起使用的商业 MP3 编码器/解码器
最近几天，我一直在研究一种在上传到托管在 Linux 机器上的网站时将 MP3 文件混合在一起的方法。
到目前为止，感谢社区，我了解到通过命令行使用 SoX 可能是从两个源实际生成混合文件的最有效方法。我还发现 Audacity 也可以用于此目的。
不幸的是，这两个程序都是免费的 - 由于专利和许可方面的法律问题，它们不支持 MP3 格式。我知道可以使用 LAME 添加支持，但这仍然是非法的，因为 LAME 也是免费的并且未获得专利所有者的许可。
因此，我正在寻找一种方法来向 Sox、Audacity 或类似的命令行启用程序添加 MP3 编码器/解码器支持，以便它可以在商业网站中合法使用。搜索再次出现空白，请问有人知道解决办法吗？
In recent days i've been looking into a way to mix together MP3 files at the point of upload to a website, which is hosted on a linux machine.
So far, thanks to the community, i've learned that using SoX over the command line is probably the most efficient way to actually produce a mixed file from two sources. I have also discovered that Audacity may also be useable for the purpose.
Unfortunately, both of these programs being free - they do not support the MP3 format due to legal issues around patents and licensing. I know that support can be added with LAME, however this still remains illegal because LAME is also free and is not licensed by the patent owners.
So I'm looking for a way to add MP3 encoder/decoder support to Sox, Audacity or a similar command-line enabled program, so that it can be used legally within a commercial website. Searches have once again come up blank, does anyone know of a solution please?

您可以简单地使用 LAME 插件，但购买涵盖您使用专利技术的专利许可。 mp3licensing.com 提供更多信息，包括版税费率。
似乎最后一项已知的 MP3 专利将在美国到期2017 年 12 月 30 日。
You can simply use the LAME plugin, but purchase a patent license covering your use of the patented technology. mp3licensing.com has further information, including the royalty rates.
It appears that the last of the known MP3 patents will expire in the US on December 30, 2017.
