I've started thinking about speex and speex stream. I wonder to know if speex can do this: ? Let assume we already have PCM stream encoded with speex (e.g. saved in a file or memowy): ? frame1 | frame 2 | frame 3 |

Dear Sir, We are 4th year students from SLIIT. So, we hope to use Speex code for our final year project. We downloaded Speex-1.0.5 version and tried to compile it. But it was given some errors regarding Ogg files also. If you can send us the compiling procedure of Speex it will be more helpful to us. We hope you will pay your kind attention for our request.We are waiting for your

Hi all, Accoring to the Table.8.1 and Table.8.2 of speex manual (Version 1.2 Beta 2), the data rates supported by speex codec for narrowband are 3.95, 5,95 ,8 ,11 ,15 ,18.2 and 24.6kbps. But when I run the code(downloaded from www.speex.org), I am getting data rates of 4,6,8,11.2,15,2,18.4 and 24.8 kbps. That is, for an input of 20ms frame the number of output bits I am getting are

Dear Sir, I am fresher for DSP domain. Currently I am working on implementing automatic gain control part. I refered public domain free source code for speex module. It's very useful for me, but I did not get exact document that what document they followd for control the gain automaticaly for a noise cancellation module. For this I did not get documents properly. So kindly suggest me which

Speexdec plays ogg files. You can simply modify it to play your raw file or even rtp capture.

Hi all, I am developing a VoIP application and have used SPEEX for that purpose; I successfully managed to port the codec in fixed-point to an ADSP-21364 processor, and the codec works fine in narrowband, wideband and ultra-wideband mode. Currently, I have chosen, in accordance with the speex manual, a 20 ms frame size in each of these modes: in other words, the input buffer for speex was set to

Thanks Jean-Marc. I do want to change Speex frame size to 320. In this case, I've changed frame size in init and modes (include framesize and subframesize). However, the audio quality becomes bad. It seems something else needs to be changed as well. Could you give a clue? Thanks, Dennis -----Original Message----- From: Jean-Marc Valin [mailto:jean-marc.valin@usherbrooke.ca] Sent:

Hi, I have some questions regarding Speex. please reply as soon as possible. where are the two filter loops applied to the raw signal? where is the residue (innovation) signal calculated? where is the innovation mapped on a codebook entry (key)? which bits of a transmitted frame are the two filters, which are codebook keys? Is the codebook from the beginning on static (so already known by

Speexdec is expecting the frames to be wrapped in an Ogg frame I believe. Since you have the raw data can't you just add the Ogg header information to this before passing it to Speexdec?

Dear Speexers :-) I am trying to change the frame size from 20 ms to 10 ms, I did that by changing the value of the frame_size from 160 samples, to 80 samples in the sampleenc.c file. The number of frames increased as expected, but the size of the encoded stream of each frame remain the same! For example, if I use quality mode # 8 (corresponds to 15 kbps), the encoded streams size in bytes equals

Thank you so much for your quick reply. It looks quite easy to change it. But, how about those codebook and excite table? I notice them have been fixed as the length of 160.

How speex cope with the difference between the codec frame length ,ie.160, and denoising algo frame length? ? The frame length of denoising algo? must be different from that of codec. Although I do not know the exact frame lenth is , it must be a certain power of 2,say 128 or 256.not 160. Then how speex handle it? ? Cheers HyeeWang

what you need to do is this: take the wireshark raw dump, read each udp packet and write it back to another file. While writing back to the new file skip the sizeof udp header + rtp header. I can't recall how many bytes you need to skip, however, I suppose it would be in the range of 36 and 32 bytes. A five line perl script will do it. - farhan On 7/7/11, Vinod Panicker <vinod.p at

Hi Alls Sorry for my newbe question I want to decode a speex multi frame stream I got 38 bytes packets and make 800 bytes buffer this is my simple code CSpeexCodec::CSpeexCodec(void) { // speex_bits_init(&m_speexBitsOut); m_pSpeexEncStateOut = speex_encoder_init(&speex_nb_mode); int nEhc=1; int nSamplePerSec = SAMPLES_PER_SEC; static int nQuality = 8;

Hi, Searched far and wide for a solution to this problem but couldn't find anything. I'm debugging a VoIP application that uses Speex and need to playback the raw speex frames to verify the quality. Wireshark helped me save the RTP payloads into a file but unfortunately, the speexdec utility seems to be wanting a valid header at the start of the file without which it reports an error.

Hi, I want to stream a file encoded in speex frame by frame (like a phone). I don't want to decode it, nor encode it. I have a speex file on disk and need to stream it one frame at a time. Speex frame size are dynamic (silence is compressed, VBR, etc.) so I need the speex specification to know how to read different frame "types". I've looked at the speex manual, but it's

Hi Jean-Marc, I want to know the possibility of expanding frame size from 160 to 320 for narrow band. What is the side-effect if do so? How many changes involved for the current code? Thanks ahead.
