A better AAC encoder: FDK-AAC

It really works, thanks!

It would be nice if you added ability to use Apple CoreAudio AAC. I'm sure its possible to do since OBS does this too (when its installed on system).

Any updates on this matter and if it's possible to add support for it? Sure would help to streamline things a little bit, for me at least.

Simple question: the initial download "libfdk-aac.zip"... is the latest version of FDK AAC Encoder??

VBR in HE-AAC is possible now??

I noticed the audio streaming client butt also offers libfdk-aac-2.dll for its users, it's 1.3 MB and supports VBR, HE-AACv1 (AAC+) and HE-AACv2 (eAAC+) with Fraunhofer's qualitative tuning, VBR & CBR and LC-AAC.

I did some tests with a sequence of white noise. I made a screenshot of the spectralview in Audition. The results are attached as PNG-pictures:

01-uncompreessed.png: Uncompressed - this is what it shoul look like

02-AAC-ffmpg_CBR_320.png: The native FFMPG AAC Encoder at 320kbit (48Khz stereo) - look at these "glitches"

03-AAC-ffmpg_CBR_384.png: Same settings but slightly higher bitrate (384kbit) - noticeably better quality

04-fdkAAC_CBR_320.png: fdk AAC Encoder at 320kbit, very good quality, but frequencies above 17Khz are cut

05-AAC_x264Pro-plug-in: AAC Encoder of the x264Pro plug-in. I don't know what encoder is used here but it looks outstanding

So my result is: For best AAC quality in voukoder use the native FFMPG AAC encoder at higher bitrates (min 384) or use the the fdk encoder and live without the 17.000+ frequencies. After some rock concerts these frequencies are blows away, anyway )

Thank you for this info! I used to compile FFMPEG with fdk aac built in and I was considering doing this again until I saw your post here.

Which profile are you using for 03-AAC-ffmpg_CBR_384? Low complexity?

Is this still one of the best audio encoders you've found that works with Voukoder?

I just use QAAC's cvbr mode for best compression and quality possible among 99.9% of audio encoders:

qaac64.exe --cvbr 320 -b 16 -r 44100 --threading -o "output.aac" "input.wav"

Sometimes I have to lower the cbvr bitrate (e.g., --cvbr 256 for 256Kbps) to make the export compatible with some audio sharing platforms.

HE-AAC does offer more compression, in QAAC it allows a maximum of 80Kbps, which butchers the audio quailty, though
