similar to: size speex file encoded

Hi i'm developing a sort of VoIP application for my ipaq using speex... I'm still at beginning and i have many problems encoding and decoding my wav files....output is only noise! Why? I'm using Libspeex 1.1.3, Embedded VisualC++ 3.0, Ipaq 3850(206 MHz Intel® Strong ARM 32-bit RISC Processor) PocketPC 2002 (Windows CE 3.0). Libspeex is complied with the definition of

I think your setup is wrong all the way. First, an uncompressed narrowband (8 kHz) file should take up 272 kB, not 1.43 MB. You're probably dealing with a 44.1 kHz file (you should downsample it first). Once encoded at quality 1, the result should take 8.5 kB, not 21 kB. As for the 92 kB, I have no idea where it may come from. Jean-Marc Le mar 03/02/2004 à 16:16, Rodrigo Parra M a

Hi, I just released unstable version 1.1.2 that contains more fixed-point work. Though it's still not 100% complete, enough have been done to make it run in real-time on ARM. In order to do that, compile with --enable-fixed-point --enable-arm-asm. All narrowband modes work in real-time with complexity 1 (some work with higher complexity) and some wideband modes also work (up to ~20 kbps) at

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

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

There is no such a thing as a "raw Speex format". Also, sampleenc.c and sampledec.c are good for learning how to use the API, but the compressed format shouldn't be used in

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, I do test runs of speex using speexenc -n [name].wav [name].spx The wav-files (6 different speech files) hereby are sampled at 44100Hz. Most interestingly, all Frames have SubModeID 5. I haven't tracked the Assignment of the SubModeID through the source code, so I just wanted to ask, if I can assume "speexenc -n" to use SubModeID 5 always? Ciao, Bj?rn -- You will

I am transcoding mp3 to wave using ffmpeg I am then piping it to speexenc for speex encoding but the speex file size is 496 bytes after the command ends https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212927.html https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212949.html https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212954.html what am I doing wrong? bellow is

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

Hi -- I'm looking at adding Speex decoder and encoder support to the Miles Sound System, a commercial library used by game developers on various platforms including PCs, the Mac, and game consoles. As part of my initial evaluation, I've gone ahead and downloaded the 1.0.4 and 1.1.1 Win32 binary distributions and played around encoding and decoding various files with the speexenc.exe 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 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).

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

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 have writen a simple JNI wrapper for speex so i could use it from Java, so far i managed to record from a raw pcm file and from the javasound inputLine and to decode the output in narrowband CBR mode and play it back still using javasound. And it sounds quite good. I haven't tried anything else because my project has no use for wideband and ultra wideband. VBR would be nice but i have
