CELT 0.9.1 is out!

Hey jmvalin, thank you and the team behind CELT for such an amazing codec. I only use it for speech (mumble) and the quality is amazing, as well as the latency.

Hello there, tried to compile celtenc with library and no conversion is performed, anyone can say why??

Here's the binaries that don't work for me:
Code: [Select]

Called with

celtenc test.wav test.oga

and nothing....

Thanks much, that's work. I'd be interested how's CELT performing as for quality in contest with Vorbis@Q6, Lame@V2 and NeroAAC@Q0.55.
Would anyone consider co-ordinate a listening test at these bitrates

the current version is celt 0.11.2


Where did you find that version? Official site still reports 0.11.1: http://www.celt-codec.org/downloads/

version 0.11.4  available at http://git.xiph.org/?p=celt.git

So, where is 'configure'? - Process it with autoconf
OK, but it throws errors. - So you are stucked with Windows?
No, I'm just sick of packages that can't compile on MSYS or Cygwin on first try. *sigh*

...dream on for MSVC solutions...

celt.c violates the C standard several times in the
  ALLOC_STACK;
  SAVE_STACK;
constructions (variable definition after statement), my compiler complains about that

could you please fix it

version 0.11.4  available at http://git.xiph.org/?p=celt.git


please for link to tar.gz archive, I don't have git installed

Really? At least msvs2010 compiles it without problems.

please for link to tar.gz archive, I don't have git installed

It's there. Click on the first "snapshot" link.

I think VS2010 uses less strict lexical rules, but perhaps it would be better to stick with the standard strictly so that the code is truely portable. I'm using ICL.

Either I cannot compile CELT 0.11.4 correctly, or it is incompatible with current foo_input_celt.

I have downloaded this snapshot, how to compile celt-0.11.4.tar.gz to exe and dlls (32bit)?

Assuming you are on Windows with MSVC < 10:

1. open MSVS and make empty project for libcelt from files from libcelt folder and build it
2. download libogg and build it
3. make separate projects for celtenc and celtdec* with linker dependant on already build libcelt and libogg libraries
* from files in tools folder (read Makefile.am as a help)

If you setup everything in those steps correctly, you should have celtenc and celtdec executables

run automation bash script provided and then as readme says just compile with ./configure; make

or forget about it

can you compile celt-0.11.4.tar.gz and upload as celt-0.11.4-win32.zip?

google doesn't help me further.

I can compile but for me it doesnot encode anything and exits.

Hi!

First, thanks for this truly amazing codec. I'm excited to see where this codec advances in the future

I'm curious if it's possible to implement a similar technology like bitrate peeling in Vorbis which was actually never used there. It would be so nice to use CELT for eg. web radio streaming where the client could decide according to it's current connection speed the bitrate it requests and switch between them gaplessly. Say, the main encoder encodes the audio @192kbps, but it can be peeled down to 96kbps or 48kbps without transcoding on the audio server by sending less data. When you listen to web radio on eg. your mobile phone while moving in your car you roam between cells but not all of them supports high speed connection for example, on EDGE the web radio player on the phone can revert to 48kbps so it can keep up with continous streaming. What do you think? As i read CELT scales very well so maybe it's not impossible to arrange encoded data in a peelable way.

Opus --cvbr --bitrate 256 --framesize 5

For files encoded with Opus using the hybrid mode, they can be stripped to just the low frequency parts inexpensively.  Otherwise, no. Part of the efficiency of the format comes from making the coding so right that 'pealing' is not possible.

On the other hand, our encoder is fairly fast— the fairly unoptimized reference code (No ASM, No SIMD) is >12x faster than libvorbis' managed mode encoding.  You should also be able to switch clients between different bitrate sources on a packet by packet basis without breaking continuous streaming.

I see. And how about the other end? Making CELT scalable to lossless? That would very nice also. 96kbps for portable listening is already nice, but what about storing correction data? Like HD-AAC does.

Can someone re-compile the celt version 0.11.4 to an exe file?
I didn't really get through how to do it by myself...
