In a "normal" frame that doesn't have in-band signalling (which nobody seems to use anyway), the frame starts with the narrowband information. If the frame is in wideband, then this will be followed by a bit of wideband information that starts with a bit set to 1 (narrowband starts with a bit set to 0). Have a look at what the Speex decoder does. You may actually want to have similar

But a decoder like speex can always be configured from information contained in the incoming stream. That makes your application more interroperable.

Hi, I had this doubt in relation to MCPS calculation for tremor: 1. How to calculate MCPS for each decode? I am using this formula is this right? MCPS= (cycles * channels * bytes/sample)/(outbytes * 1M) Where cycles are for one decode. And eg: Channels = 2, byte/sample =2 and outbytes = 4096 Is this equation right? 2. I observed that while decoding the

Hi All, Some time ago I emailed this list and mentioned (as well as a couple of techinical queries) that I was trying to contact the PRS for information on the copyright licencing requirements of a non-profit on-line radio station, a few people expressed interest in this and asked I keep them updated. Well I just sent my third email (transcript below) informing them that I will assume a further

Hello, speexers. I'm new to the list and new to audio compression. I've been asked to look into creating a digital archive of 20-minute speeches (sermons) and speex seems to be what I need. My experience is in image compression; I shepherded gzip, deflate, zlib, and png through the IETF process, put "image/png" through the IANA registration process, and I maintain several

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

Does anyone have an (overhead) paging system that they like that works with SIP? We've got a client with an old paging system that (supposedly) just takes an rj11 POTS connection, but when we put an SPA Cisco adapter on it, it doesn't auto-answer the call, so paging never happens.

Hi, all, I am porting speex on ARM7TDMI, I have done some optimization, the result is that the encoder and decoder need about 60 MCPS for 5.96kbps bitrate and complexity 0. Can someone give me informtion about Speex optimization on ARM7? Another question, my ADC and DAC are 12 bits, but Speex codec is 16bits, Did someone try to modify speex to 12 bits? I think if I modify speex to 12 bits, the

*Problem I want to solve:* We have 3 sites: A, B, and C. Network admins should have access to all three. (this works as-is). Desktop support should only have access to their site. (Tech A to site A, Tech B to site B, Tech C to site C). *How I think I can do it:* Working with keys? Admin's public key will be on all the client machines, and thus, the client machines will always

Hi Jean-Marc, I remember you said that the SDP tells the mode information. Is SDP what you called in-band signalling?

if the new draft in the manual is used. I don't find how to tell the decoder which mode(NB/WB/UWB) is used in the encoder. The RTP header don't contain the mode field and I don't find the mode information in the coded frame either. Does this mean we have to use NB decoder in all cases?

In a word, I don't what's the standard of speex payload format. The file doc/rtp.txt is for what? Is it not for rtp payload? I find that rtp.txt is more detail that draft02.txt Which rtp docment should be followed? Anyone else has written the RTP wrapper already?

Hi Jean-Marc, Suppose that the incoming rtp stream is coded by different mode(NB/WB/UWB) each frame. Can speex decoder adjust its mode per frame in real time embedded system? I think it's hard to do that, so I think it's better to add an mode parameter in the decoder interface. What do you think? Best Regards, Lianghu -------------- next part -------------- An HTML attachment was

Hi Marc, Thanks for your quick response. So if VAD is enabled then VBR will be enable although it's a special VBR. How about take out the VAD code from the VBR and remove the code else?

You need more than an ATA. You need something with an FSO and FXO. I've used Linksys/SPA3102-3.3.6 and been happy with it.

Dear Sir/Miss: I'm very sorry to bother you,but I've found a bug in the Speex,Version 1.2beta1,and also I've have some questions. I'm deeply impressed by the work you have done in the coding and decoding of speech signal.But when using speex,I encoutered a bug,that is when in 32K mode,the window size is still 200 samples,but not 400 samples,the bug will bring the problem of

Thanks Michael, I will proceed like this. I think I didn't have UDP 655 forwarded on the remote server, will do that (had it at my client's router). If tinc connects, will both server and client see each other, for example I will be able to access all webui's running on SERVER from CLIENT side? For example, SERVER is running webui of Tvheadend on 192.168.0.4:9981 How can I access that

Hi Jean-Marc and All, Two things need your confirmation/suggestion. 1) First, I think there is a bug in libspeex/lsp.c line 512. /* hard limit ak's to +/- 32767 */ if (a < -32767) a =32767; // This line should be changed to if (a < -32767) a = -32767; if (a > 32767) a = 32767; ak[j-1] = (short)a; 2) About the RTP wrapper for VoIP I'd like to use the
