What is CELT? What is a .CELT file? How to convert it!

I've read around on the internet in so many different places about CELT being a very quick and efficient audio format ( 1.3 ms to 24 ms anywhere from 32-96 kHz) and I have recently run into some .CELT files that I need to somehow convert into regular .wav files ( and vice versa ).

I've already attempted multiple ways of doing this - with most ending in failure. I managed to obtain about 5 different WIN32 versions of CELT and none of them are able to convert my .celt file into a .wav file.

I tried the decoder function (while in the command prompt, of course): celtdec input_file.celt output_file.wav

but it never seems to work. I even tried making the input file a .oga file ( I read somewhere this would work) yet still the same old error message: "This doesn't look like a CELT file." appears every time I try this in any of the versions.

I know I look like an idiot new-comer to the forums, but I really need some serious help! ohmy.gif
If anyone has experience with CELT/ the CELT decoder/encoder your help would be greatly appreciated.

Where did you get those .celt files?

CELT is a part of Opus now. It went through many bitstream changes until around mid 2011 or a little bit before. celt-tools (and later opus-tools) encode and decode with a OGG container (with .oga file suffix**).

So to sum up:

* We don't know if those .celt files you have are real.
* If they are real, we don't know when they were created (what bitstream version is used) and how they are contained.
* CELT is a part of Opus now. Look for Opus's latest code in http://git.xiph.org .

** One of the developers seems to like the .opus extention. But that's very new:
