similar to: Release of Speex?

Hello all, I am experimenting with Speex in a mobile VoIP application, and it seems that it is worth stuffing more than one codec frame into a single RTP packet; mainly, that sending several frames per packet relieves the underlying network socket connection, which is notoriously problematic in mobile devices. RFC 5574 defines the exact way how to put multiple Speex frames into a single RTP

Dear Speex developers, I am currently experimenting with Speex on Symbian smartphones. I have compiled the Speex library, and I am now using it in the following way: 1. Record 320-byte buffers of data in PCM16 format, 8000 Hz sampling rate. 2. Feed the resulting buffer to an instance of a narrowband Speex encoder. 3. Send the encoded data over RTP. 4. Upon receiving on the other side, feed the

Hi Marian, I took a brief look at RFC 5574 and as far as I understand, you can simply do it like this: SpeexBits b; speex_encode(state, some320bytePCM1, &b); speex_encode(state, some320bytePCM2, &b); After that, get the encoded data with speex_bits_write and put it in your packet.

Hi everyone, Just to let you know that version 1.2beta3 is out. The main change is the split into libspeex and libspeexdsp. Basically, libspeex keeps the codec (just like it was for 1.0.x) and libspeexdsp has all the new components. Other changes include a new jitter buffer algorithm and resampler improvements/fixes. This is also the first release where libspeex can be built without any floating

Hi all, I am a newbie here and just started using speex in our lab. During compiling my voice application with windows-compiled version provided today, I am getting "unresolved external symbol _speex_wb_mode". I am probably missing some setting with VS6.0 linker... (I am a bit new to windows too) If anyone could point it out, I would appreciate it. - Tim -----Original Message-----

I'm currently working on packaging the latest version of speex for Fink, a Mac OS X package manager. Our current speex version is at 1.1.6, and several new programs require a newer version, which is why I'm working on the update. When 1.2b3 was released and some symbols were offloaded to libspeexdsp.1.dylib, this broke the library on OS X since libspeex.1.dylib kept the same install

Hello Tristan, Thank you. But I am using libspeex library. Does the speexdsp library be included in it? Or it needs to be installed separate. Appreciate the help.

Hi Aymeric, > 2 questions: I count 4 :-) > * Do you "feel" that the current svn is enough stable Yes. I'm planning on releasing it as 1.2beta3 this week. Even in normal time, I try to keep svn in good shape so it is almost always better than the last release. And even when it breaks, Speex bugs tend to be very obvious and easy to reproduce (no segfaults that happen once a

Hello, I am from a small Czech software company (circletech.net) working on software for mobile phones. We are currently starting a development of an Voice IP software, and consider using speex for voice compression and decompression. The software will be Symbian OS C++ program. Is there anyone who has actually used speex Symbian OS port for realtime voice compression and decompression on mobile

Hi All, We are using speex for linphone in blackfin fixed point platform. The speex version we are using is svn-14525. If we don't disable vbr by "--disable-vbr", the sound quality will be very bad in linphone. But if we disable it, sound will be perfect. I noticed in the speex.org, there is a comment like this: > >Speex 1.2beta3 is out >December 11, 2007 >The most

Hi, I'm using the Speex codec on my Blackfin-based board, and plain-C performance is pretty poor. Decoder is OK (something 25 MIPS for wide-band). But Encoder is not (wide-band quality 8, complexity 1): - 162 MIPS with Analog-Devices lib - 128 MIPS with 1.2beta2 (faster but not working) I don't worry that much, as it's not the optimized version, and everything is running in SDRAM.

Hi, I am an user of speex codec.Can I ask some question about the speexcodec 1.2beta2 on installed to linux(fedora 6) thanks! After I downloaded the latest version of codec then I type the commands to install : configure -prefix=/home/...../test -enable-shared -enable-static make make install then I try to compile my encode.c here is the encode.c of mine: =====================================

Jean-Marc, Frank, I have stumbled across a similar situation regarding optimization. I seem to have a similar setup as Frank does with a fixed 48khz in and out. The wideband mode and ultra-wideband modes are really what I?m looking for. I have a test application that reads audio, downsample to 16kHz (or 32kHz), speex encode, speex decode, upsample back to 48kHz, and playback. If I remove

Hi Jean-Marc, after some problems with getting svn to work here I finally made it. Problem is, you write that I cannot use libspeex and libspeexdsp at the same time now -- because I use a "live" system (mic-in -> speex_enc -> speex_dec -> headphone out) and I can run the AD1836 audio codec on 48 kHz only, I cannot use my program now (because I use speex resampling...) So I

Hi, The Speex bit-packer already does everything you need. Just call speex_encode() multiple times to encode multiple frames and call speex_decode() multiple times to decode these frames.
