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 noi...

...ardware capability of protecting the frame with multiple CRCs. Hence we might have a rough estimation of how many bits are wrong in the frame (no error correction though), in case of few corrupted bits, is it better to use the current frame for decoding?

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?

...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?

...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?

...e 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?

...FTs sizes for normal block and short block are 160 and 40 respectively. It's not really clear how the function "compute_bitrev_table" calculates the values. Could you quickly explain the idea behind the function so we can try to implement it on the fly?

...and although i couldn't hear any particular difference in the decoded audio quality, the cycle count of the encoder dropped of average 40%. Is there a reason why it has been set off by default?

...fixed point decoder and the other way around. Both are not working. I'm using CELT 0.7.1. It shouldn't be relevant but the source file is freq: 32000 channels: 1 frame_size = 256 bytes_per_packet = 64. Has anybody had my same problem? Any suggestion?

...kes me think the code is in someway ready to work on these kind of platforms. I don't see the above definition used anywhere in the code though. Does anybody know if CELT could work on platform with 16 bits char or if any attempt has been already tried? Thanks!

...h_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 integer?

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?
