Linux上最好的he-aac编码器？-Besthe-aacencoderonlinux?

Nero AAC is the only one as far as I know. Even if FAAC supported HE-AAC it would be useless, since as an encoder its pretty awfully designed and its quality is not even competitive with LAME, let alone a good AAC encoder.

据我所知,Nero AAC是唯一一款。即使FAAC支持HE-AAC也没用,因为作为一个编码器,它的设计非常精巧,而且它的质量甚至不和LAME竞争,更不用说一个好的AAC编码器了。

Kostya on the FFMPEG team is currently working on an AAC encoder but it has a long way to go--its not ready for primetime with LC-AAC, let alone HE-AAC (its not even committed to the repository yet). The first step before anything will be to get the ffmpeg decoder to support HE-AAC; currently it can only be decoded through FAAD.

FFMPEG团队的Kostya目前正在开发AAC编码器,但它还有很长的路要走 - 它还没有为LC-AAC的黄金时段做好准备,更不用说HE-AAC(它甚至还没有承诺到存储库)。任何事情的第一步都是让ffmpeg解码器支持HE-AAC;目前它只能通过FAAD解码。

I don't believe there is any HE-AAC encoder on any platform with a more permissive license than Nero's at this point in time.

我不相信在任何平台上都有任何HE-AAC编码器,其许可证的许可证比Nero目前更为宽松。

I've been using neroAacEnc for quite a while now, and I'm largely satisfied with the results. If you're on Linux, making an .AAC file out of an .MP3 or whatever else, is quite easy, all you need is a small wrapper script, that takes care of decoding into .WAV and after encoding, removes the .WAV file.

我一直在使用neroAacEnc已经有一段时间了,我对结果非常满意。如果你在Linux上,用.MP3或其他任何东西制作.AAC文件非常简单,你需要的只是一个小包装脚本,它负责解码成.WAV并在编码后删除.WAV文件。

Be advised: Converting from one lossy encoding to another further reduces quality. So when you can live with .MP3 and you don't have lossless sources, you better stick to them.

建议:从一个有损编码转换为另一个有损编码会进一步降低质量。因此,当你可以使用.MP3并且没有无损源时,你最好坚持使用它们。

Here's a small script, that converts from .FLACto .AAC, it accepts only .FLAC files as arguments:

这是一个小脚本,从.FLAC转换为.AAC,它只接受.FLAC文件作为参数:

#!/bin/zsh

for file in ${argv[*]}; do
    flac -d ${file}
    neroAacEnc -q 0.6 -if ${file%%.flac}.wav -of ${file%%.flac}.aac
    rm ${file%%.flac}.wav
done

This script is sequential, but it can be easily made into a multithreaded script.

此脚本是顺序的,但它可以很容易地制作成多线程脚本。

There is an encoder called accplus which is under the GNU license available here.

有一个名为accplus的编码器,它在GNU许可证下可用。

Another encoder: mp4tools

I don't have an idea about the quality, but I just found enhAacPlusEnc

我对质量一无所知,但我刚发现了enhAacPlusEnc
