Intel compiles of exhale-v.1.1.1-36964d20 are now at Rarewares. :)

And, sincerely, today CPUs are fast enough. I get more than 100x speed with exhale on my laptop. 

What, on single core?

Not in my case... one zero less :) 10.6x, to be exact, when encoding to preset 3.

yeah, I get about 16x from a moderately spec'd thinkpad from 2 years ago.

Awesome and thanks :) I'll try this out for sure.

Not to forget a Happy New Year to CRHelmrich, john33, IgorC, and so many HA fans that would fill a book. :)

After trying Exhale on macOS with ARM SoC and on Android, it's Linux's turn and I have compiled Exhale on Raspberry Pi 4, without errors or warnings.

If you want to make exhale more accessable please submit a proper package build to a distribution's package repo instead of posting random builds/binaries. Repology looks very sparse in that regard, https://repology.org/project/exhale/versions

Still nothing from ffmpeg people? At least decoder...?

How do you know? Apparently it's not written anywhere, and if I listen to e.g. Music: "Walking", the 16-kbps HE-AAC version sounds to me like Parametric Stereo of v2 is being used. On the higher bitrates you're probably right, but there it may make sense not to use Parametric Stereo.

Thanks for the info IgorC. Good to know.

Surely Netflix will be using Fraunhofer's encoder since Fraunhofer announced it though.
And "Netflix has licensed Fraunhofer’s high-quality xHE-AAC software". I don't think they'd pay for a license and then end up using a free version of the encoder. But damn, that would be a cool story if so lol.

I mean, they would still presumably have to license the relevant patents?

I have zero knowledge of license and patent requirements etc wrt audio codecs and encoders etc. Logically though, it leads me to ask if a patent is required then how can we use exhale? But is that because we do so for personal / non-commercial purposes? I guess it's the same for mp3 encoders.

I await to be schooled on this matter lol

Depending on the exact terms of the AAC patent license you might not be able to (legally), that's how it was until the last MP3 patent expired in 2017.

But there's significant effort and general lack of reward for going after little guy end users for this.

Plus the proliferation of "illegally encoded" mp3s made mp3 what it was to the point where a device that didn't decode mp3s was effectively seen as defective, which allowed them to collect money for legally licensed mp3 decoders from the big  hardware and software players like Apple, Microsoft, etc.

News:
Netflix Now Streaming xHE-AAC Audio on Android Mobile

I wonder whether Netflix uses exhale or some commercial encoder by FhG.
I mean, they would still presumably have to license the relevant patents?
There's a Netflix blog post which states that "content was encoded using the xHE-AAC encoder provided by Fraunhofer IIS", and the news article that Igor linked to says that "Netflix has licensed Fraunhofer's high-quality xHE-AAC software". Which likely means they licensed the usage rights (i.e., relevant patents) along with it.

Regarding exhale, I just finished a 1.1.2 beta without changes to the audio quality but hopefully somewhat better compatibility with some players/devices. You can find it on Git branch develop_ipf, revision 193dc26. Please report any regressions regarding gapless playback, seeking, or similar issues.

NOTE :
The version is still shown as v1.1.1 when using -V/--version

Indeed, I updated the year but forgot the version number. Fixed, along with some other minor things. Please continue testing with the new revision 9ed76ef, which I consider a first 1.1.2 release candidate.

Well, I'm not a patent/copyright lawyer, but exhale's license contains a "no patents granted" disclaimer similar to most publicly available MPEG audio or video coding software. I believe that disclaimer answers your question.
