Hello everyone, I was curious if anyone has performed any listening tests or done work with solo instrument performances with the CELT codec? I experience quite a bit of noise coming up with a heavily tonal stimulus, the worst offender being a trumpet. I understand some of this behavior is to be expected, this is a perceptual codec afterall, but was curious if anyone was able to find an elegant

...ed solution to the problem (since I'm probably going to be distributing my software long before the IPR for the pre/post filter is available) and I'm curious to see how it stacks up against the pre/post filter.

Has the requirement for FrameSize decreased? I cannot seem to instantiate a mode with a frame size smaller than 120. I have been using a framesize of 100 on previous versions.

Hi everyone, I've recently been making various changes to the way the modes work and the supported frame size. On new feature that may be of interest to some is that CELT should soon support changing the frame size dynamically within a stream. By that I mean varying the amount of audio (in time) transmitted at once, not the compressed size -- which has always been variable. That would

Hi guys, I am on a C55x stereo implementation of CELT 0.7.1; I am using 100 sample frame size and writing 58 Bytes per Packet. At the output of the decoder I see one channel reconstructed perfectly, but the other channel has random corruption that appears to be a sinusoid with a period of the frame size. The artifact is non-periodic and appears to happen randomly during the audio stream. Anyone

I checked out a snapshot of code from the latest commit on Wed, 23 Mar 2011 00:32:49 +0000. I am running this on a C55x processor. (fixed point enabled) Line 98 of ecintrin.h read: # define EC_CLZ(_x) (_lnorm(x)) This lead to about 30 compile errors complaining about "identifier "x" is undefined" I changed it to: # define EC_CLZ(_x) (_lnorm(_x)) and the compiler is much

hey guys, I am using the tip of Git and attempting to compile for a C55x DSP. I am running into a couple compile errors and have found the source of the issue. The errors: "celt.c", line 957: error: declaration may not appear after executable statement in block as well as "celt.c", line 2303: error: declaration may not appear after executable statement in block Both of

Hello everyone, I would like to access the raw CELT encoded bytes by using the command line interface but I am having some difficulties. I do not know how to unpack the Ogg Vorbis wrapper and the STDOUT option just filled my command line with ASCI characters. Anyone have luck dumping the bytes to a text file? Also inputting them back to the celtdec function would be helpful information. Thanks,

Hello everyone, I just wanted to see if anyone else is using PLC on the C55x and having success? I am seeing some issues and was curious if I was doing anything wrong/stupid or maybe I have found a bug? I am using: - the CELT library from OPUS 0.9.5 ( I checked the git repo and no check ins have comments about PLC, I assume it hasn't been updated) - FRAME_SIZE: 240 - PACKET_SIZE:

Hello everyone, I have been having trouble utilizing the PLC function (I think). In older versions (0.7.1) a pointer to NULL did the trick, but with code from the tip of the GIT repository, this method causes the codec to crash on the C55x fixed point platform. I have not determined where the crash occurs. I have also attempted to pass in an array of zero's and this creates an echoey, reverby
