Abstract:
Blind Comparison between patched FFmpeg's native AAC encoder, FAAC, FDK-AAC, LAME, and AC3(ATSC A/52, Dolby Digital) at 128kbps.
All are encoded and decoded by FFmpeg.

Encoders and settings:
FFmpeg's native AAC encoder, v4 patch, ABR. The patches are available in here. https://trac.ffmpeg.org/ticket/2686
ffmpeg.r.55212(v4-patch applied) -i input.wav -c:a aac -strict experimental -b:a 128k out.mp4
FFmpeg's native AAC encoder, v7 patch, ABR
ffmpeg.r.57288(v7-patch applied) -i input.wav -c:a aac -strict experimental -b:a 128k out.mp4
FFmpeg's native AAC encoder, v7 patch, VBR
ffmpeg.r.57288(v7-patch applied) -i input.wav -c:a aac -strict experimental -q:a 0.7 out.mp4
FDK-AAC encoder 0.1.2
ffmpeg.r.57288 -i input.wav -c:a libfdk_aac -b:a 128k -afterburner 1 out.mp4
FAAC 1.28
ffmpeg.r.57288 -i input.wav -c:a libfaac -q:a 97 out.mp4
LAME 3.99.5 V5
ffmpeg.r.57288 -i input.wav -c:a libmp3lame -q:a 5 out.mp3
FFmpeg's AC3 encoder
ffmpeg.r.57288 -i input.wav -c:a ac3 -b:a 128k out.ac3

Samples:
25 Sounds of various genres.

Hardwares:
Sony PSP-3000 + RP-HT560.

Results:



Conclusions & Observations:
The FDK-AAC was the best encoder at 128kbps. LAME and FAAC had significantly poorer scores. FFmpeg's native AAC encoder didn't reach the LAME and FAAC level quality. In v7 patch, the VBR was significantly poorer than the ABR. The FFmpeg's builtin AC3 was one of the worst encoder in the test, comparable to the native AAC encoder, v7patch, VBR.

I'm not familiar with ffmpeg as a frontend, what real codec settings does it use? ABR, VBR-old, VBR-new, CBR?

Awesome test. It is nice to see the native AAC encoder starting to sound better than the native AC3 encoder.
FAAC performing as good as LAME is quite surprising.

FAAC uses VBR in -q:a settings of FFmpeg. LAME uses VBR (vbr-new, as it's lame 3.99.5) in -q:a settings. It's not possible to use LAME ABR from the FFmpeg (as in 2012)

The patches are not applied to the main trunk, currently. klaussfreire is now close to post a v8 patch, which fixes M/S encoding which will be on by default.
He says he will split it into smaller patches and post them when it's ready.

FAAC VBR and LAME VBR have roughly the same quality in 128kbps and upwards, according to my past test:

if you set bitrate -> cbr (or abr as a non-default option)
if you set quality -> vbr_default

How can I do that?
CBR

VBR
ffmpeg59804 -i input.wav -c:a libmp3lame -q:a 5 out.v5.mp3
ABR - failed.
ffmpeg59804 -i input.wav -c:a libmp3lame --abr -b:a 128k out.abr128.mp3
I've got this error message. Unrecognized option '-abr'. Error splitting the argument list: Option not found

From a quick look, there seems to be at least an implicit -q5 comandline argument added by ffmpeg, instead of LAME's default q0 (with VBR new). Is that correct?

Any "best/transparent" VBR for FDK-AAC ? (like -c:a libfdk_aac -vbr 5)

(Note: I'm just a user.)

Yes.
As you can see just a few lines above rate control.
The default is assumed 5 but changeable (-compression_level in ffmpeg maps to -q in lame).

Is 0 a default internal to the backend and used if a frontend never calls lame_set_quality() ? Or is it set in the frontend?

There is no mention of a default in lame.h . Only recommendations (2,5,7) in the comments.

If it's internal, and older versions of liblame default to a safe value. Anyone of us can send FFMPEG a trivial patch removing their assumed default.

ABR was noticeably better, so I decided to test the ABR. The VBR is immature.

The FFmpeg trac server was inaccessible, so I provide the copy of the patch. (temporally) http://zak.s206.xrea.com/bitratetest/aac-i...s-wip-v2-v7.zip

Thanks for this interesting analysis, Kamedo2. Would you mind posting the bit-rate average (over the samples in the test) for each codec in the test? I'd like to compare your data with Winamp's AAC VBR 4 on your test-set.

And is it correct that the V7 patch VBR encoder averages more than 250 kbps on the French speech sample, but you still gave it a score of less than 3? blink.gif Sounds like an encoder bug to me...
