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 would love to see podcasters adopt the Speex format to deliver clear speech audio at wideband or ultra-wideband formats. However, podcasters want something that can easily play on Windows, Macs, and even Linux web browsers. The Speex website has some nice audio demos, but it doesn't actually offer any HTML embedded samples using actual Speex format. Would there be a way to do this with

this is not really a development question, but i didn't find another mailing list to ask it. any idea why size of wav file doubles when it is encoded to speex and back to wav: $ ls -ls testi.wav 40 -rw-r--r-- 1 foo foo 40674 May 4 14:38 testi.wav $ speexenc --denoise --agc --quality 10 testi.wav testi.spx Encoding 8000 Hz audio using narrowband mode (mono) $ ls -ls testi.spx 20

Dear Speex codec community: I am working on conversion of voice files. I could not figure out how to use speexdec.exe 1.2.3 in piped mode in order to avoid the creation of the potentially large intermediate *.wav or *.pcm files. Any pointer to web or file of instruction is appreciated. Attempt (one long command line, failed): type d:\test.spx | "d:\speex 1.2.3\bin\speexdec.exe" - -

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

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

Hi, I just started using speex recently and I've been having problem with Speex ver. 1.1.10 decoder. I used Speex to encode a wav file to spx then decode it back to wav file to see the voice quality that results from different speex options. Somehow, I couldn't get the original wav file back. I used both Speex ver 1.1.6 and ver 1.1.10 to both encode and decode, despite the same output

Hi, I am experiencing some unfortunate problems when encoding WAV files to spx using version 1.0.4. A "click" which is not present in the original WAV file is added to the end of the spx file. Is this a known problem, and if so, which version of the encoder should I switch to... and if I have to switch the encoder, will I also have to switch the version of the decoder? Sincerely,

Hello, I encode a file with speex so i get a .spx file but i want to decode the same file i get only one second of my file and nothing Some idea why?

OK, that was a stupid error in the le_int prototype. It's fixed in svn now.

Hi all, i'm going to try to create an app using libspeex (Speex 1.1.10) and Visual Studio and just have a few questions. First, what's the difference between libspeex and libspeex_dynamic? Do I need to include both projects in my new workspace? Next, how do I enable fixed_point using libspeex? Am I correct in assuming that an ARM processor would be able to record speech as speex files

Hello, On the announcement page for Icecast 2.3 it mentions "Streaming support for ogg speex, ogg flac, ogg midi". I've googled around and not found any free clients that support streaming speex. I looked at svn for libshout2 and it doesn't seem to support speex and skimming through the list archives I only see mention of speex last February, which seemed to indicate it would

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
