similar to: How to get podcasters to adopt Speex?

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

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

Sure, I could download OpenOffice and try it, but it's nice to be able to

Ok, I made my own sample HTML page and it worked on a vorbis OGG file that I embedded. No need to download a player (other than the directshow filter if it isn't already installed) and no need to download sample. It just played within the browser. I should probably try to release a podcast like this at 16 kbps and see how well it's received. -----Original Message----- From: Jean-Marc

Ah, but speex.org should lead by example. Instead of posting wav files, why not post the actual speex files as well?

Hi , I want to use the read.table to the following example 'data.txt' format: a b c d e f SPX LSZ 100 C 0 34.4 SPX LSZ 100 P 0 1.3 SPX LSZ 105 C 0 30.3 SPX LSZ 105 P 0 1.85 SPX LSZ 110 C 0 26.4 and I want to have the columns a,b,d read as the 'character' data, a the remaining columns as 'numeric'. What I did was:

Hi Steve, thanks for the advice. I placed the appropriate functions outside the while statement but I still get this error at the while loop: First-chance exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. Unhandled exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. It looks like the same error. I've

Hello developers, I have a question about supported bitrates for SPEEX. Regardless of whether I specify a 10kbps or a 8kbps bitrate, the encoded .spx file is the same size and have the same PESQ value. This makes me wonder if SPEEX supports arbitrary bitrates, or only a certain set. A few more details about my configuration: I am using SPEEX encoder version 1.1.12 I am encoding a narrowband

Hi, I am pretty new to R and would like to follow the code in the paper below, tradesys package. but I am stuck at the 2nd page where x<-tsts(spx) is written. Could anyopne help me why I am getting an Error :"could not find function "tsts" ". I guess I need function call "tsts". where can I find that function ? I installed tradesys, zoo, RUnit packages but I

hey guys, I just compiled an application similar to sampledec.c (for speex 1.1.10) and it was fine but when I executed it, the app exited without doing anything. I'm using MS VC 6.0 and this was all I got - First-chance exception in sampledec.exe : 0xC0000005: Access Violation. Has anyone encountered this / does anyone know how to deal with it? by the way, sampleenc executed perfectly... When

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

At speex.org, I read that Speex is well-suited to internet audio streaming and audio books. However, I am having difficulty finding or creating audio-book-type material of acceptable audio quality vs file size. For the sake of comparison, look at the speex sample in Ubuntu's example-content_26_all.deb vs http://podcast.msnbc.com/audio/podcast/pd_mtp.mp3 The mp3 sounds ok, streams and seeks

Hi! I'm looking for a documentation of the .spx file type? I want/need to know how such a .spx file is built up. I want to create a .wav to .spx converter. And additionally a .spx player. I already searched the net and the speex site but I couldn't find anything useful. Maybe I'm missing something? Thanks for your help! Best regards, Peter -- Neu: GMX FreeDSL Komplettanschluss mit

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,

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

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
