HE-AAC v2 is better than v1 up to ~36 kbps (valid for any encoder like Nero, Fraunhofer, Coding Techonologies).

v2 makes more harm than benefit at 48 kbps. http://www.mp3-tech.org/tests/aac_48/results.html While this test is pretty old the v2 and v1 encoders were already mature at that point. Nowadays the situation hasn't changed a little bit.

those tests are from 2006. This test from 2013 is better: http://www.iis.fraunhofer.de/content...er_xHE-AAC.pdf



another report: http://nprlabs.org/sites/nprlabs/fil...y%20Report.pdf



I can't find some diagrams with opus as a comparison, i saw some last year but cannot find the links.

Let's put it straight. This information from the same organizations who push xHE-AAC and HE-AAC v2/v1. v2 is more expensive than v1 so it's convenient

Anyway Fraunhofer HE-AAC encoder (Winamp) uses
v2 - 32 kbps
v1 - 48 kbps.

It's possible to force v2 at 48 kbps but it's not recommended by the same AAC developers.

It's always possible to encode a few samples and listen for yourself.

Thanks for taking the time to make these binaries LoRd_Mulder. However with this latest one, every time I try to encode from FLAC - any FLAC - I get the message "Error parsing input file", and the thing quits. This happens on each of the i686, sse2, and avx builds. Converting a WAV made from FLAC fixes this. The FLACs in question play without issue and were encoded using libflac 1.2.1 through 1.3.1. The FLACs have no issue being parsed by the two-year-old 0.1.9 release at the opus site and otherwise playback/decode just fine.

ED1: I have tried all of your builds going back to 20140413, and they all have the same issue. This lead me to believe I am doing something wrong, or that there is something about the way I generally encode that is causing problems. But I just made a few new FLACs from WAVs using libflac 1.3.1, no metadata or anything, and still your builds quit with the parsing error. It does not seem plausible to me that your builds have had this issue for 2+ years, so what am I missing? Some dependency or other?

ED2: I just tried the 1.1.3 build from videohelp and it failed with the same error. More googling revealed that FLAC support is only in the official build? That's the only thing that makes sense (it should not have taken me this long to figure out, anyway). You don't think you can bake in FLAC input support in your next build, do you LoRd_Mulder?

You can easily confuse xHE-AAC and highestly optimized HE-AAC (such as Fraunhofer Winamp's encoder) at 64 kbps.
Where do find xHE-AAC binaries (encoder and decoder) for Windows desktop (no app) ?

The binaries that I compiled do not support FLAC input, sorry.
I am not a big fan of the "dependency hell" around several FOSS libraries, such as FLAC, Ogg, Vorbis, and etc., so my "releases" are as simple as possible.

The Opusenc from the foobar2000 Free Encoder Pack has FLAC support
You can open it with 7-Zip.

I did not build opus-tools with libFLAC, because build these binaries primarily for use in LameXP, where built-in FLAC support is not needed. LameXP uses separate FLAC decoder

(I may consider building with libFLAC next time)

Thanks for the heads-up - I'll stick with that for now.

Here is a set of fresh Opus v1.1.3 binaries:
opus-tools.2016-10-16.zip

There have been some fixes in the Opus Git "master" since the last build. Also, this time, all 'opusenc' binaries have libFLAC enabled.

How do you encode your xHE-AAC/USAC samples for your listening tests then ?

Opus 1.2 alpha outperforms HE-AACv2 at ~32 kbps VBR for the first time.


Scores of blind listening test at 32 kbps VBR:
1. Opus 1.2 alpha (exp-df24252) - 3.22
2. CELT (music) Mode - 3.28
3. HEAACv2 (FhG Winamp, VBR 1) - 2.92

It would be good if they compared opus 1.2 alpha with xhe-aac.

It also would be good if there will be any available xhe-aac encoder at all, now wouldn't it?
