I have found several low-bitrate codecs, namely g.729, and another open source one dubbed "Codec2". I wasn?t able to find a command line, win32 encoder for these... much less a java player applet solution that I can embed on web pages. a.

Hi, I noticed that speex.org has a banner that mentions that Opus is better than Speex in all aspects. The supported bitrate range for Speex seems to be as low as 2kbps though but Opus can only go as low as 6kbps. Is this one aspect where Speex is still preferred? (I understand that it's not a very common scenario though). Thanks, Manpreet. -------------- next part -------------- An HTML

...Sorry for my typo, the flash size is 8MB (Byte) :-) Unfortunately I cannot use another flash because I'm working on a proprietary board. Jean-Marc, thanks for your suggestions. I thought to use fixed point for convenience, but I can work on floating point too, so I will take in account the codec2 (I didn't know it). Moreover, if you all have other suggestions to give me I appreciate! ;-) Cheers, Daniele.

Hi Jean-Marc, thanks a lot for your reply. > Well, the first question is whether you want encoding, decoding, or > both. If there's one you don't need then you can remove that > (unfortunately, there's no easy way right now). You're right! I forgot to say that I need only the encoder side (and only for voice).

Hello. Voice quality when calling - this is one of the most important in the PBX. You need to record the quality parameters for each call to improve. Because the overall quality of a call can only be determined upon completion, I did it in the HangUp handler and wrote in custom fields of CDR. This worked well in asterisk 11. In asterisk 13 I did not find a handler after the call, but before

For anything below 6 kb/s, I would actually recommend using codec2 rather than Speex or Opus.

..., do you think opus shrink the stream enoguht?) This is going to be a problem. Assuming you mean 8 mega*byte* (and not 8 megabit), that's still only 2 kilobit/second. Opus pretty much requires 8 kb/s, so 4 times what you have. The only codec I know that can do 2 kb/s with reasonable quality is codec2, and the implementation is floating point. > Since I'm using FIXED_POINT, I have to pass also --disable-float-api? Yes. The normal API has calls with both int and float, so if you compile with FIXED_POINT, the float calls do a conversion to int before using int internally. If you disable t...

Hi, I'm fairly new on codecs, I'm trying to implement a communication between two PCs. The data rate should be of approx. 6Kbits/s, this 6Kbits/s can just be the useful data. Any encapsulation (for example UDP , RTP, etc ...) can be present even if that means to rise the overall bit rate. Also if this rate can be achieved on Asterisk. For exemple I've tried to change de rate on

Hi, Anyone know how to set up tftp server for grandstream. I gues it should be somethink like <tftpserver-dir> <mac-address> firmware.bin config.txt Is this correct ? And how should the config-file look like. ? I had search sipphone.com but did'nt find anything. /HHA _________________________________________________________________ Rethink your

Hi folks, I am totally new to audio streaming codecs, and just looking around. Trying to figure out what else I can put on top of my very long list of projects. So a few days ago I figured out that fldigi a digimode application for Amateur Radio supports a dual 1000 Baud PSK mode. I thought "that's fast" and started looking around which sort of Data I could put into that. A

Dear Tariq; About elastix.org, this can be use with Asterisk or it is coming as a complete IP Telephony, Call Center, IVR and Reporting? Because, I do not need to install another IP Telephony on the server which already has asterisk which is an IP Telephony, this will cause a problem in the service (for example, when listening for SIP port of 5060).
