In Linux how convert to HE-AAC ?

[Aug]

Thanks for reading my topic.
I not see in Linux an easy way to convert to HE-AAC. ffmpeg and nvencc not has HE-AAC.
Have any software or dependencie to allow convert to HE-AAC ?

Have an nice week.

Prerequisites:

Install FFmpeg:
If you don't have FFmpeg installed, you can typically install it using your distribution's package manager. For example:
Debian/Ubuntu: sudo apt install ffmpeg
Fedora: sudo dnf install ffmpeg
Arch Linux: sudo pacman -S ffmpeg
Ensure libfdk_aac support:
The libfdk_aac encoder provides HE-AAC support. In some distributions, this might require a separate installation or compiling FFmpeg with libfdk_aac enabled due to licensing restrictions. Check your distribution's documentation or search for "install libfdk_aac ffmpeg [your_distribution]" if you encounter issues.

Conversion Command:
Once FFmpeg is set up with libfdk_aac, you can use the following command structure to convert an audio file to HE-AAC:
Code

ffmpeg -i input.mp3 -c:a libfdk_aac -profile:a aac_he -b:a 64k output.m4a

Explanation of parameters:

-i input.mp3: Specifies the input audio file (replace input.mp3 with your file).
-c:a libfdk_aac: Selects the libfdk_aac codec for audio encoding.
-profile:a aac_he: Specifies the HE-AAC profile. You can also use aac_he_v2 for HE-AAC v2, which offers better performance at very low bitrates and supports 2+ channels.
-b:a 64k: Sets the audio bitrate to 64 kbps. Adjust this value as needed; HE-AAC is designed for efficient encoding at lower bitrates.
output.m4a: Specifies the output file name and format (typically .m4a for AAC).

Example for HE-AAC v2:
Code

ffmpeg -i input.wav -c:a libfdk_aac -profile:a aac_he_v2 -b:a 32k output_hev2.m4a

Note: While libfdk_aac is generally considered a high-quality AAC encoder, always verify the compatibility of HE-AAC with your target playback devices, as some older hardware might not fully support it.

You can enable HE-AAC in ffmpeg by installing libfdk_aac, compile ffmpeg with --enable-libfdk_aac, then use -c:a libfdk_aac -profile:a aac_he for proper HE-AAC conversion.

Thanks for all replies.
In moment not is possible for me test how compile ffmpeg. I only use ffmpeg4 and the current version in Ubuntu repository not does HE-AAC.
HE-AAC has better quality than AAC and Opus ?
HE-AAC file size save is irrevelant if compared with AAC ?

[Kakujitsu]

Audacity with the
FFmpeg Library.

sudo apt-get install audacity

Also Opus has better quality at the same bitrates.

[dannyboy48888]

Fdkaac has a standalone enocder. If you can't compile you can use ffmpeg to make a wav and feed it to fdkaac

Thanks for all replies.

@dannyboy48888
Thanks for saying about fdkacc, but the software is only windows. Here is Linux.

I see have better and more simple alternatives than HE-AAC.
Opus is better than HE-AAC ?
How is the compatibility of Opus with current TVs ? Have issues or is compatible with any TV in market ?
I only want convert videos with audio stream if possible using the less size with good quality and see AAC not is exactly the correct choice.

[dannyboy48888]

I'm in Debian. https://packages.debian.org/trixie/fdkaac far as comparability android tvs that can install VLC will have no issues with opus. He-aac worse case will only decode the base layer on base devices (think early Blu-ray players with USB) For most compatibly use lc-aac or mp3

[DKruskie]

its so easy to compile ffmpeg in ubuntu, if you want i can send you a link to do it.

[El Heggunte]

It should be even easier to compile the standalone executable fdkaac.

                               assumed. Spec is case insensitive, therefore

 --long-tag <name>:<value>    Set arbitrary tag as iTunes custom metadata.
 --tag-from-json <filename[?dot_notation]>
                              Read tags from JSON. By default, tags are
                              assumed to be direct children of the root

                              that contains tags can be specified with
                              dotted notation.
                              Example:
                                --tag-from-json /path/to/json?format.tags

Might be a silly question, but is fdkaac available in your repository? I'm running MX Linux and it's available in the Debian repository.

You could always install Wine and run any Windows encoder that way.
Either install it yourself (you should also install WineTricks to make working with Wine a little easier), or another method might be to install PlayOnLinux. You could use it's File/Install menu and type foobar2000 into the search box in the window that opens. PlayOnLinux should step you through the process of creating a Wine prefix, downloading the foobar2000 installer and installing it in Wine. Foobar2000's converter can be used with any command line encoder, and it includes a GUI for creating conversion presets for roughly a dozen different audio encoders, including FDK AAC (see the screenshot below). It doesn't come with fdkaac.exe, but you can download it yourself and tell foobar2000 where to find it. I'm running foobar2000 in Wine, along with several other Windows programs.
