Aften 0.0.8 is out - Page 35

Yobbo · 17th August 2007, 22:56

well I got WavtoAC3Encoder here, which says it uses Aften 0.06. I just downloaded Wisodev's 0.07 R561 build from a few posts up... Now what do I do? Sorry to be a pain

Kurtnoise · 18th August 2007, 07:32

Just put it the GUI folder...

Yobbo · 18th August 2007, 08:20

What exactly do I put in the gui's folder? The whole Aften folder (there's lots of stuff in there!). Or, just the Aften.exe which is in the Win32 subfolder? And also, where exactly do I pop it? In the Gui's main folder? Or in the Win32 subfolder? Or the "ansi" sub-subfolder? Sorry again for the newb questions!

Yobbo · 19th August 2007, 21:22

No one can help me to update my Aften gui?

Kurtnoise · 20th August 2007, 15:33

If you use AftenGUI 1.4 and Aften.exe revision 561, you're up to date.

Then just put aften.exe in the same AftenGUI folder, load your files , choose a target bitrate and go !

Yobbo · 20th August 2007, 22:12

OK thanks!!

I just wanted to drop in and say thank you to everybody working on Aften and AftenGUI. I appreciate it.

Hi! Just want to clarify this: " I have substituted the FFmpeg MDCT implementation with the one from libvorbis, which is faster. " - Justin @ Aftenblog

Because I found out that the one from libvorbis is based on "The use of multirate filter banks for coding of high quality digital audio" by Sporer et al. But this paper was presented a very long time ago (1992).

I am wondering why this has been chosen over other implementations and why there has been no updates since version 0.06 on this. If I am not mistaken, I think there are other more efficient methods, right?

How does it compare against other mdct implementation in terms of speed and quality, why is it "faster" then?

@wisodev and kurtnoise, i would just like to ask what you used to create the GUIs. (I am planning to create one that will operate stereo settings only)

Thank you very much!

Kurtnoise · 22nd August 2007, 08:35

mine's developped in Delphi. I would like to create a X-plateform GUI (gtk+ or something with the Aften API) but I 've a lack of time.

Thank you very much!

My GUI is created in Visual Studio 2005 using Visual C++. The app is based on MFC Dialog template. You can download latest source code of my app from Subversion repository (here you can browse online the source code) or just by downloading source package.

bout the GUIs: wow, that was fast! I'll probably check out the MSVC first since its the one im using now. to kurtnoise and wisodev,

The main reason for using the libvorbis implementation was that the original MDCT was from FFmpeg, which was (and is still) not very fast. In fact, there is a discussion going on now at ffmpeg-devel about creating a new FFT (and hence MDCT) implementation.

Also, cpu-optimized versions of the libvorbis mdct were already out there ready to use. This wasn't part of the decision, but has been a definite advantage.

I'm sure there are faster implementations out there. At one time DarkAvenger was doing some experiments using FFTW with Aften. It was a while ago, so I don't remember if it was any faster.

jruggle · 10th September 2007, 05:00

I just released Aften 0.0.8. Yes, I changed the version numbering. I hope it's not too confusing. I think the new versioning scheme will be easier to use. Anyway, here is the Changelog.

fixed piped input from FFmpeg
added support for MPEG channel order remapping
restructured audio input. enables raw pcm file support.
bugfixes in MMX/SSE2 code
stack align hack for x86 MinGW with threads
API changes
SIMD and threads usage is shown and is configurable
screen output gets updated every 200ms to reduce load
SIMD detection changed to compiler-independent inline assembly, thus nasm/yasm not needed anymore

patul · 12th September 2007, 03:22

@wisodev: Any chance you would update your Wav to AC3 Encoder with this new release?

Yep, I have just released new version of WAV to AC3 Encoder at version 0.5. You can download it from here (changelog and downloads archive).

Thanks,
wisodev

Thank you. I appreciate especially the raw pcm file support. One question about this: Do you expect the same channel order in the raw pcm file as you do in the wav file? Or do you expect the Blu-Ray pcm channel order?

Same channel order as WAVE unless you specify the option to change it. What channel order is Blu-Ray?
