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 ?
