Hi, To enable stereo in celtenc do I need to change anything other than #define CHANNELS 1 to #define CHANNELS 2 The reason is after I do this the audio sounds distorted. Please let me know if I need to do anything else or whether I need to investigate what's happening at my end further. Paul.

A small issue, but missing. Something like this would be helpful: - printf ("celtenc (CELT encoder)\n"); + printf ("celtenc (CELT %s encoder)\n", CELT_VERSION); til

Hi, I'm currently testing libcelt (celt-0.9.1) on my Openwrt/Kamikaze RDC-3210 platform and although I'm able to Crosscompile on my Ubuntu 10.10 machine without errors, the resulting celtenc doesn't seem to work properly. Ran ./configure via the Openwrt makefile first (activating fixed-point) ; I first produce a S16_LE Raw PCM file (48Khz, stereo) : test.pcm Then I try to encode

Hi, I am running celt 0.11.1 on my mac which is running osx lion. I invoke celt such as so: celtenc original.wav output.oga I do not see any files being encoded, the wave file is stereo 16 bit at 44.1kHz. Any ideas on why this is not working? I also tried the opus git repo for the latest sources, but that also does not produce an encoded file. Thanks -- -baeksanchang -------------- next

Hi All, I'm looking to package up celt for inclusion in Fedora as the next stable release of ekiga/opal will have support for it. I've run into two issues in compiling it into a rpm. The first is a show stopper, then second one not so much of an issue but thought I'd report it for reference. The first issue is due to the celtdec and celtenc explicitly define rpath. I get the

Does someone have a link to step-by-step instructions to making the Line-In on the console sound card a MOH source? I know this has to work somehow.

I have been trying some different sample rate and bitrate combinations to get a feel for how CELT behaves. I then encoded it with a couple of different frame sizes and sample rates. There were some small differences, but nothing horrible. So, I decided to run with 24KHz sample rate with 16 bit samples. This seemed like a reasonable tradeoff against the quality degradation that my folks

Is there are description somewhere of how CELT packs into the .oga file? Trying to reverse engineer it from the intertwined celtenc code is suboptimal. -a

I thought this had been around before but I can't seem to find anything about it. I have a customer whom prior to upgrading to Asterisk invested in one of those boxes that plays your company sales campaign into the MOH port on your key system. For reasons of message maintenance he wants to keep the box as part of the new system. Can I couple this to the sound card in the Asterisk server

Hello everyone, I'm evaluating the Celt in terms of robustness against bit errors. So what I have done is encoding a wav file using the \tools\celtenc.exe and then manipulated the wav file according a desired bit error rate or burst error length. But the Celt decoder stops decoding with the first bit I manipulated even if this bit is not in the header. So is there a way to do the test

Hi, What kind of latency is expected using 8,16,32 khz? I am trying to do a realtime stream server, and I am having latency above >500ms ( I capture the sound using the mic, encode it and send it to the client). I am using ALSA system, a SB128 PCI and a 800Mhz P3 . What can I do to lower the latency? I tried a test : arecord -t raw | speexenc - - | speexdec - and I found that I also have a 500

Hi, I'm new here so an introduction. I'm Stefan de Konink, I have a diverse past, present and future in coding, content creation and a background in speech research. As introduced on #celt I want to do some promotion for the codec. I was positively surprised by the availability of something 'almost done' and totally usable in the form of celtclient.c, attached is a tiny

I am having problems getting Ices to work with ALSA. If I use arecord (arecord -D plughw:0,0 output.wav) I can record the input from my microphone into a file. The playback works perfectly. However, if I use Ices with the same values I hear nothing on the receiving end of my broadcast (although I can connect to it). In order to do a further test, I setup a <savefile> tag in my
