Hello All, I have recently started working on SPEEX and thanks to the nice tutorial and examples, i was able to encode/decode files as per the command line programs speexenc.c and speexdec.c I tried the sampleenc/sampledec but, i know its only for the raw data. My question is what kind of raw data should be used to test them? Also, is it possible for me to use speex without any of the headers but

Hello all, I am using the speex APIs in a gnuradio block. I used the similar code as in the sampleenc.c/sampledec.c which works perfectly fine. My compilation does not give any error, but when I run the python test, it complains that speex_nb_mode is undefined. I tried to declare it explicitly then it as const SpeexMode *mode = NULL , then i get an error that i cannot initialize the const

As a note, with the latest versions, I get this "new" failure, when cross compiling for windows using mingw: CCLD speexdec.exe speexdec.o:speexdec.c:(.text+0x4af): undefined reference to `_imp__waveOutGetNumDevs at 0' speexdec.o:speexdec.c:(.text+0x54d): undefined reference to `_imp__waveOutOpen at 24' speexdec.o:speexdec.c:(.text+0x5aa): undefined reference to

hello, i am experiencing some persistent compilation errors with both the 1.2beta2 release and the svn speex-trunk: ====================== speexdec.o(.text+0x23b): In function `out_file_open': /speex-trunk/src/speexdec.c:158: undefined reference to `_oss_ioctl' speexdec.o(.text+0x268):/speex-trunk/src/speexdec.c:168: undefined reference to `_oss_ioctl'

Hello, I'm working on an Opus encoder block for GNUradio (a signal processing toolkit). I was wondering if there's some formula/heuristic for estimating the packet size average case / worst case given a certain encoder setting (assuming VBR). I need to provided a reasonable estimate to the GNUradio memory allocator. --Albin

hello again, on NetBSD the library ossaudio needs to be linked in for speex to build. i did it by hand in the src/Makefile by altering LDFLAGS to "-lossaudio". it now compiles properly. thanks for your time, b On 10/11/07, Jean-Marc Valin <jean-marc.valin@usherbrooke.ca> wrote: > > Seems like NetBSD doesn't like the ioctl calls.

The following patch (based off of the current CVS tree) is necessary to compile Speex on IRIX (or any other system that doesn't include getopt_long in the system libraries). I would suggest further that src/getopt_win.h be renamed to getopt_long.h since it's not just Windows that lacks getopt_long. Michael Index: configure.in

Hi, I came into a crash when using 32-bit `speexdec` and found that there's an address overflow in function `print_comments()`: static void print_comments(char *comments, int length) { char *c=comments; int len, i, nb_fields; char *end; if (length<8) { fprintf (stderr, "Invalid/corrupted comments\n"); return; } end = c+length;

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" - -

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

Hi Chris, Thanks a lot for your help. I've been able to resolve all the errors except one. I don't have ogg.h header file, so when I try to build Speexdec.exe, I get an error d:\speex\speex-1.1.5\src\speexdec.c(44) : fatal error C1083: Cannot open include file: 'ogg/ogg.h': No such file or directory I don't have this file, but as I wrote in my previous mail, an ogg_static

Hi, I have done some code cleanup of my speexenc patch for skeleton support. Also a warning message have been added to let the users know that some decoders may fail with skeleton output enabled. The speexdec patch enables speexdec to play skeleton enabled speex file. Thanks in advance for the feedbacks. --tahseen -------------- next part -------------- A non-text attachment was scrubbed...

Note also that the packet size you give the encoder also acts as an absolute max on the bitrate. For example, if you ask for 32 kb/s VBR but give a max packet size of 120 bytes, then you're absolutely certain the bitrate will never go over 48 kb/s.

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

Several weeks ago, we posted a message seeking information about time sources.? There were many helpful and educational responses. An excerpt from one of the responses is included below.? We have been following up with regard to how SDR capabilities might be used for obtaining time using SDR dongles as well as using the time source product referenced in that response. Our SDR investigation has

Hi, I've downloaded the Speex-1.1.5 code and am trying to compile the Speexdec code using Microsoft VC++ 6.0 IDE. When I try to open the speexdec.dsw workspace, I get a dialog asking to locate the ogg_static file. I simply cancel that message, and then the project is opened in the VC++ 6.0 IDE. Now, when I simply try to compile the program, I receive this 5 error messages. error1.

I have an audio file compressed by JSpeex that I'm trying to decompress on the iPhone. I've been trying to work from the speexdec example in an attempt to port the core logic to ObjC. I have a class that does the decode and passes the result back to another class. (currently the other class is a unit test.) My other class is writing the converted output to disk. I compare the results of my
