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

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 Conrad, Thanks for your help. I am unlucky. No i have this following error : source='speexdec.c' object='speexdec.o' libtool=no \ depfile='.deps/speexdec.Po' tmpdepfile='.deps/speexdec.TPo' \ depmode=gcc3 /bin/sh ../depcomp \ arm-linux-gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -I../libspeex -I/usr/include -O2 -fno-exceptions -O2

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

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?

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...

Description =========== This patch adds support of CMake meta build system, so you can generate Unix makefiles, VS 6.0-2017 projects and many more. Features ======== * Win32 and Linux tested * Travis CI test added * Generates working Visual Studio 6.0-2017 solutions * Generates working Unix Makefile * Supported options (<option> - <default value>): * `ENABLE_FLOATING_POINT` - on

The encoded speex file should, by convention, be given the '.spx' extension rather than '.wav', but that is not the issue. What appears to be happening is that the '.wav' extension on your named output file from speexdec is not being recognised as '.wav' and, consequently, the file is being written as 'raw' data without the wave file header. I am not sure

Hi Bernhard, Can you confirm I'm understanding everything correctly? You encode with the same encoder and then decode with either A) blackfin assembly and fixed-point or B) fixed-point only on Blackfin. Then A) sounds bad and B) sounds good. If you do the same in narrowband, it sounds OK. Is that correct? If that's the case, it's *probably* some kind of bug and/or invalid assumption

Hello all, I'm testing the Speex codec for my diploma thesis on a BF-533 Blackfin under uCLinux (2005R3 RC3 release). I successfully compiled the Speex (1.1.11-svn) and I can encode/decode wav-files on my STAMP-board using the speexenc/speexdec sample apps. But I encountered that the decoded file sounds strange/noisy, when compiling with "--enable-blackfin-asm" +

I downloaded speex-1.2beta3-win32 binaries, and used the speexenc.exe and speexdec to process the file male.wav download from http://speex.org/samples I used both the narrowband and ultra-wideband mode: >speexenc -n --quality 3 male.wav n3.spx Encoding 8000 Hz audio using narrowband mode (mono) >speexdec n3.spx n3.wav Decoding 8000 Hz audio using narrowband mode (mono) Encoded with Speex

Hi. I have some trouble in my case, I build speex project with mipsel-linux-gcc .but when I copy speexenc or speexdec to my taget platform, and run, the message "./speexenc can not found" has been append.

Hi all, I'm trying to use libspeex 1.1.10 on an ARM926EJ-Sid(wb) rev 3 (v5l). I executed the speexenc and speexdec test files and they can encode and decode. But I'm getting 95% of cpu utilization on the codification and 44% on the decodification. I saw in the post: http://lists.xiph.org/pipermail/speex-dev/2005-June/003485.html that this version of speex works fine on ARM

Hi all, I've another trivial request: Is there any particular reason why speexenc and speexdec return 1 on successful completion? It would be preferable if they returned 0 unless there were errors, to be consistent with other *nix utilities and to allow for easier scripting (eg speexdec sample.spx && cp sample.spx somewhere) Would anyone be against this? TIA, Bernard. --

Hi, I've enocded and decoded a file using speexencexe/speexdec.exe respectively. However when i use the example code to encode a file and use speexdec.exe to decode it; not only do i get a file that is 3kb larger than if i had encoded it with the .exe but also I get a "this doesn't look like a speex file" message, and it is unable to decode it. I've checked around and it

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
