similar to: problem using speex

Hi Sorry ? I have just signed up for speex-dev, because I am experiencing some problems ? I hope you can help! I have used Speex before in the past, and I am just revisiting it for a new project. I am experiencing a few issues, however: I have various Windows machines (either XP or Win7) I have got Speex for Windows 1.0.5 installed On one XP (SP3) machine, all works fine ? including speex

Ok here is something I couldn't see on the description page. We need to convert to 8 bit audio right? I'm assuming narrow band is 8 KHz 8 bit. Wide band is 16 KHz 8 bit. UW band is 32 KHz 8 bit audio?

On my personal web pages hosted by my ISP I have a collection of speex files with names ending, as usual, in '.spx'. My ISP does not provide for scripting or CGI but thanks to the "Home-Brew Streaming" idea of Dr Tak Auyeng, www.drtak.org/teaches/ARC/speex/, my friends with Windows XP can listen to such a recording without the need for a prior download of the whole file and

Would it help if I scale the input wav data before encoding to spx? One interesting thing is if I encode the same wav file to spx(or decode the same spx file to wav ) on Windows platform, then there is no such big clicking noise, samething is true if I use floating_point speex library to encode/decode on WM2003. Problem happens only on WM2003 using FIXED_POINT library. Thanks Yanxin -----

Dear experts, I am trying to understand the structure of the Speex .spx file, so I can packetize each frame in one packet for example, and in the receiving end, I can decode a file that has all the received frames (some of them may lost). I tried to figure out what is the delimiter used to separate the frames but I could not so far. I also tried to deleted some data from the .spx file or change

Can you post the input and output file on the web and specify what options you're using (use speexenc/speexdec, *not* your own code).

This is a really good point, and definitely a recurring theme on this mailing list. :) I wonder, what are some better options for handling this issue, other than to keep saying "just use 8/16/32kHz"? - Extend Speex to support other sample rates (seems unlikely..?) - Integrate a resampling algorithm into libspeex - Maintain a list of recommended resampling libraries that work well

Hi I have just written a small c programm which reads in speex files and outputs them as asci text numbers. This is necessary as for writing a hw testbench for decoding tests, since thy only read ascii files :-(.I can't read the bitrate properly from the header file. It's allways -1. Please see example below and attached c programm. I wan't to check for a fixed bitrate (8000).

Hi, I think I see what you mean, though I haven't been able to listen to your wma file (not everyone has a wma decoder). The problem probably only lies in the VBR tuning for wideband which hasn't received much work yet. One way to check that is to encode in constant bit-rate and see what the results are. I'm pretty sure you'll notice the problem appears only at (CBR) quality 5 or

Please consider using 16-bit 16kHz (wideband) instead. It's a huge increase in audio quality and the bitrate is still very low, especially if you take advantage of Speex features such as VBR. 8kHz seems totally inappropriate to me for desktop streaming audio, let alone 8-bit samples. Or perhaps your recording equipment is an original Sound Blaster from 1989? (Even that could record at

I am running speex 1.2beta1 on WM2003 using FIXED_POINT option, I got big clicking noise during encoding or decoding randomly, I got more noise if I spoke louder or made the MIC sensitivity higher, for example, when I encode the wav file to spx file, the original saved wav file does not have such noise, the noise is added only after it's converted to spx format. The floating point version of

Dear Speex community, I am having problems to get the Speex Decoding API to work properly in our project. I am working in an embedded project with a very limited RAM and Flash memory and would like to use Speex encoded files to save memory while having good voice sounds in our speakers. I have developed a Windows-based tool to convert WAV files to Speex files in packets of 160 bytes (we are

thanks for getting back to me, i have uploaded a zip file containing some sound files that demonstrates the issue. http://www.bogus.net/~olav/ess.zip this contains s.mp3 original wav file (mono) converted to top-quality mp3 (370K) s.wma windows media encoder with 19khz voice compression ( 62K) s-2.spx speexenc --vbr --quality 2 on the wav file ( 63K) s-9.spx

oddcast currently doesn't do speex, or ogg-speex. One of the biggest problems currently with speex (and flac too) is client support. I've just recently added ogg-flac support to oddcast (not yet available) and in my testing found that client support for this format is horrible. On windows, Winamp and Foobar choke on it (most likely assuming that if it's ogg, it must be vorbis)

Have you thought of using jspeex (http://jspeex.sourceforge.net/)? The other way I can think of is to do the same as the Annodex Firefox plugin (http://www.annodex.net) and use VLC.

I spent some more time with the Ogg and Speex format specs, and I realized that using the "application/ogg" MIME type is technically sound, since Speex is contained in an Ogg wrapper. To get full browser support, though, it is best to rename it so its file extension is "ogg". Some browsers do not support files where the MIME type and file extension are different, based on

Hi, We'd like to announce the first draft for the Speex RTP profile. It was written essentially by Greg Herlein, with some help from Simon Morlat and I. We'd like to get some feedback on it before it is sent to the IETF. Basically this will allow all SIP based VoIP applications using Speex to inter-operate. For those interested, there's already Simon's LinPhone (www.linphone.org)
