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: read.table("data.txt",header=T, colClasses=c("...

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 (8KHz) wav file The exact commands I issue are: spee...

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,...

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 attached the code below Thanks, Mon Portion of the revised code: decstate = speex_...

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 f...

I've checked to web for the format of the .spx file, and have not found anything complete. I've attached what I have deciphered so far. There are a few question marks in my tables that I want to understand better. I've also attached the .spx file that I used in the example values. I'm trying to take Speex-encoded data from an em...

...t to recomment for Macintosh) On of the primary concerns is that I am able to edit the title, author, album, and comment information for the file. The manual states that "/Speex bit-streams can be stored in Ogg files./" Thus I assume that it is possible to encode speex as either ".spx" or ".ogg" At the moment, I am assuming that there are many tag editors for the ogg format, and none for the .spx format. A quick look at the hexdump of a .spx file starts with: [pmdumuid@Andottie speex-xmms]$ hexdump -C ~/male.spx | more 00000000 4f 67 67 53 00 02 00 00 00 00...

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 d...

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 with quite minimal del...

...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 -rw-r--r-- 1 foo foo 16405 May 4 14:46 testi.spx $ speexdec --mono --rate 8000 testi.spx testi.wav Decoding 8000 Hz audio using narrowband mode (mono) Encoded with Speex 1.2rc1 $ ls -ls testi.wav 84 -rw-r--r-- 1 foo foo...

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 don't know why it gives me error. Thanks http://r...

...m 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 encoding from command line (eg c:\speexw\speexw mywav.wav mywav.spx") On Win7 machine playback and encoding works OK as well. I have a new XP (SP3) machine however, that when I install the codec (running Speexw.exe version 1.0.5), it causes errors to occur ? such as ?rundll32.exe ? Application Error ? the application failed to initialize properly...?), and th...

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 lib...

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 libspeex library does not give me such noise(but runs slow of course). Any suggestions? Thanks a lot! Yanxin -------------- next part ---------...
