Getting CELT to work under Windows
Hi, My name is Riccardo Micci i downloaded the CELT source code and I compiled it under Windows. This is meant to be a preliminary study for my company's project. When i run CELT it encodes and decodes the file back saying "Encoder matches decoder!!". When i try to play the output though the result is just noise and clicks. The only changes I've applied are some #defines to

CELT decoder complexity
Hi, We're using Celt 0.7.1 at the moment. We're thinking to update the code to a newer version of it. Is there an appreciable complexity (decoding time) difference among versions (0.7.1 - 0.8.1 - 0.9.1 - 0.10 - 0.11.1)? If so, which one is the fastest? Thanks Regards Riccardo Riccardo Micci Senior DSP Engineer, Wireless Group Cambridge Consultants Science Park, Milton Road

MAX_PERIOD
Hi, In order to fit the decoder in memory in our embedded architecture we set the MAX_PERIOD #define equal to the frame size. This doesn't affect the code bit accuracy in normal decoding. The #define it's used celt_decode_lost function though. Is it possible to get celt_decode_lost to work with a value different from the default? Thanks Riccardo Riccardo Micci Senior DSP Engineer,

Celt_decode_lost function (File: P0773)
Hi, I'm using Celt version 0.7.1 in low complexity mode (i.e. no pitch information). In case a packet is lost i was planning to use the celt_decode_lost function. I realised though it uses pitch information inside. Does the celt_decode_lost function still works with no pitch information? Are there some changes to be done? Thanks Regards Riccardo Riccardo Micci Senior DSP Engineer,

CELT complexity question
Hi, I'm testing CELT 0.7.1 speed performance and I'm focusing now on the complexity switch. I've dug in the archive and i found some information. Is it still true that there are two ranges? - 0-2 low complexity mode - 3-10 high complexity mode If no input is given is 2 hence low complexity mode the default setting? Does the complexity mode affect decoding as well? Thank you Best

Bitrev for FFT
Hi, Our DSP has a built-in bitrev instruction so we're exploring the possibility of calculating the bitrev every time instead of filling the table during initialisation, hence saving some memory. Our frame size is fixed to 320 samples. The two FFTs sizes for normal block and short block are 160 and 40 respectively. It's not really clear how the function

Celt 0.7.1 High complexity VS Low complexity
Hi, I was checking complexity modes of CELT 07.1 encoder. If i got it correctly everything is driven by pitch_available variable set in celt_encoder_create function. By default it's set to 1 hence high complexity mode is used all the time. I tried to disable it and although i couldn't hear any particular difference in the decoded audio quality, the cycle count of the encoder dropped

FIXED_POINT
Hi, I've recently successful built and run CELT under Windows using "testcelt.c" example file. Since I'm about to port it on a embedded platform i activated the FIXED_POINT #define. I included fixed_generic.h and without other changes to the code i tried to encode and decode the same file i previously used. The output though is completely saturated i.e. it jumps from -32768 to

Celt 0.7.1 Fixed math
Hi, I'm using Celt 0.7.1 in fixed math mode. In the celt_encode function, if the variable has_pitch is true, the function pitch_search is called. Within this function the find_best_pitch subfunction is called. Here the variable "float score;" is defined. Is this right? I was expecting not to see any float declaration in the fixed math code. Is it possible to redefine it as

BYTES_PER_CHAR
Hello, I'm porting CELT 0.7.1 to an embedded platform and unfortunately (at least for me) CHAR is defined as 16 bits. I now got the vocoder compiling but when i compare the encoded output with a windows build, they don't match. Among the other problems i think that the char definition is one of the biggest players. I've seen in arch.h the following definitions: /* 2 on TI C5x DSP */

Error resilience
Hi, We're testing CELT (version 0.7.1) error resilience capability. We've used already celtdec packet-loss options. Hence we know what to expect in case of whole packet loss. How does Celt respond to a broken encoded packet? Is it always better to discard it and decode the missing frame through decode_lost? We have the hardware capability of protecting the frame with multiple CRCs.

Possible Bug
Hi, Fiddling with Celt i found a possible bug. I'm using CELT 0.7.1, frame size 256, sample rate 32k and bitrate 64k. Here is the scenario: decoding side, celt_decode function. The "dec" structure is created at each function call and it's initialized with ec_dec_init function. The attribute "end_byte" is not initialized though. Decoding a file the behaviour is the

Stereo <-> Mono
Hi, Does Celt (in particular version 0.7.1) exploits correlation between the two channels in stereo mode? In practice, is it possible to use the two channels as two mono signals without affecting quality?

A (minor) bug and a request
Cheers all. I believe that the first line in the function FLOAT2INT16 in celt.c which is now: x = x*32768.; should be: x = SCALEIN(x); This only makes a difference if you change the SCALEIN and SCALEOUT macros (which I do). The new feature I would like to request is the addition of a CELT_RESET_STATE control for both the encoder and decoder. I cache encoder and decoder instances and

Auth driver
(resending to the list; I apologize, I'm not using my usual email client) Hello, That's actually great news. The perspective of working in-tree didn't make me particularly happy. Could you point me to any documentation or examples? While I can find many plugins in the repo and around the Internet, I could find none which add authdb drivers. Best Regards, Riccardo P. Bestetti

RES: RES: Problems with ntlm_auth --helper-protocol=squid -2.5- ntlmssp
What do you mean with "... ntlm_auth --helper-protocol=squid-2.5-ntlmssp does respond only BH..." ? Is it happing in a command line test ? Remember that this helper wait for a NTLM "hash" not a clear user and password, as basic helper does. The best way of testing is to put in use, inside the squid.conf. I've be using it for some months without problem. -----Mensagem
