similar to: where to go for Speex help

Hello, I know my question has been asked before because I spent the last week searching the web for how to use Speex in combination with WaveIn/WaveOut and I ran into a few posts, but none of them answer the question. There is still a lot of confusion how to use WaveIn/WaveOut and Speex by junior developers such as myself. Even after examining code for SpeexDec and SpeexEnc, I cannot get clear

I am giving serious consideration to abandoning waveOut multimedia and the wav format, for most of the audio in my C++/MFC project. However, I've never done any programming with a codec, and I still can't see how to step into Ogg Vorbis. If I convert all my wav files to ogg, there seem to be two major issues I'm facing: 1) What exactly will I replace my waveOut functions with? 2)

Thank you for such a quick response. The only reason I started with Char buffers is because WaveIn and WaveOut on Windows XP accept/emit WAVEHDR structures, which store audio data in LPSTR, which is Char*. typedef struct { LPSTR lpData; DWORD dwBufferLength; ... } WAVEHDR; When I was going from Char to float and back looked very wrong to me as well, but I was just not

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

Again, thank you for helping me. I know this might seem like a trivial matter to you and other experts in the field, but believe me, there are a lot of programmers, whose posts I saw on the web, who tried to use WaveIn/WaveOut and Speex and failed. As I understand it, WaveIn just buffers audio data according to the bit rate specified. So, if we use waveFormat.wBitsPerSample = 8, then each Char of

I am having one frustrating time trying to decipher why ov_read is failing in my MFC/C++ application, and I see in Google results that others have had difficulty as well. These google discussions generally involve libraries, dll's and linking options, as though there are perhaps some basic incompatibilities between ogg vorbis and win32 and/or MFC/C++. Very confusing. If I pass fopen a

Evgueni, Don't listen to this guy. The last thing someone confused about types should use is a union. Listen, whatever types you're using, you're just dealing with data in memory. For an array, it's just a big block of data in memory. You need to know how that data is stored in memory. For audio data, WAVEFORMATEX tells you that with its contents. Don't let types

Hello, I'm trying to use the speex decoder on Windows Mobile 5. I have compiled the debug version of the lib for WM5 PPC. I am running this test on an HTC TyTn phone. I'm decoding 4Kbits narrowband speex audio. Each decode call takes a buffer of size 100 bytes. The problem is that each decode call takes around 130ms to complete. This is too slow for the audio to play back if I stream

I am trying to insert a bit of ogg vorbis decoding into my MFC/C++ program and send it to my waveOut functions. // AudioFile.cpp #include "vorbis/codec.h" #include "vorbis/vorbisfile.h" . . . OggVorbis_File vf; FILE* pFile; pFile = fopen("verdes_2.ogg", "rb"); int err = err = ov_open(pFile, &vf, NULL, 0); . . . ov_clear(&vf); In my

Hello Friends, I am trying to use speex-1.2beta3 version for echo cancelling. On my WinCE board I am using WaveIn/WaveOut functions to record and playback audio. I am receiving audio data on udp socket, then playing it on speaker using WaveOutWrite function. I registered callback to capture microphone data, then data chunk came from socket ( which I played on speaker) and data captured from

Dear Group, I'm running the following setup; Yoper v2, Kernel 2.6.8.1-7, Wine 20040914 on a Toshiba Satellite Pro 4600. The Toshiba has a Yamaha AC-XG. In addition I have a USB Plantronics DSP100. After some tweaking I got wine to install x-ten lite; I have pasted my config file; [WinMM] ; Wine supports the following sound drivers: ; winearts.drv ; for KDE ; winealsa.drv ; for

I'm not sure what input/output format you're trying to use, but it looks wrong. You're using the float functions that take +-32767 values and you're feeding (or converting) chars. Unless your machine has very special chars (which I doubt), a +-32767 value just isn't going to fit in. This has nothing to do with Speex BTW, it's just handling the audio data properly.

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, Please excuse my ignorance but I'm having trouble with a very basic matter: I'm using vorbisfile to stream audio to the waveout device in Win32 (using waveOutWrite). I'm basically reading packets from an ogg file and streaming them using a simple buffering scheme. The thing is, this works great when the bitrate is more or less constant but the audio sounds garbled if there is a

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.

Hi, Jean-Marc, I have another quick question, I got following message when compile speexdec.exe: Linking... libspeex.lib(sb_celp.obj) : error LNK2001: unresolved external symbol _lpc_window Release/speexdec.exe : fatal error LNK1120: 1 unresolved externals Where does this lpc_window declare?
