similar to: WaveIn/WaveOut and Speex

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

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

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'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.

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

Hello, all. 1) ACE does not work for me I am in a voip project using Speex, failed to have hte Speex ACE work. here is how I initialize it: /** * Configurations : * #define BITS_PER_SAMPLE (16) * #define SAMPLE_RATE (8000) * #define CHANNEL_NB (1) * #define DURATION (20) * SPEEX_MODEID_NB */ _eco_state = speex_echo_state_init(_encframe_size, 10*_encframe_size); speex_echo_ctl(_eco_state,

well i discoverd, HL uses waveIn, which is a part of the DirectSound ... so ... is there a Wine binding for waveIN ? - -moritz angermann

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

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 actually testing it with the main (and only) developer of this PulseAudio backend for Wine and recently

Hi, I am trying to encode raw wave data stored in a buffer using the Speex API (The raw wave data is created using the waveIn* functions - probably irrelevant information here). It is a 5 second clip, 16bits/sample, 8000Hz mono (which gives a buffer size of 80kb for the wave data). I have followed the exact procedure found in the manual available from the web site, except that

Hi Guys, I am trying to incorporate the speex AEC into my RTP stack. Trying to diagnose why the echo is not being cancelled I enabled DUMP_ECHO_CANCEL_DATA as per the docs. The problem is that the dump files the AEC generates are of different size. As I understand this and looking at echo_diagnostic.m, the files are supposed to be of same size. Can someone give me a hint as to why this could

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)

Hi, My name is Patrick, i am french, and i am developping a softphone for pocket PC using speex. Sorry in advance for my bad english. So i have make an GUI in C# that use the speex functions through dll write in C++. And the encoding and the decoding using speex seems to work not too badly.(i test with a wave file) My problem is that i need to get audio data from the microphone. In order to do

Thanks for your reply. I changed my code to: if (speex_preprocess_run(preprocess_state, shortPointer) == 1) { speex_encode_int(enc_state, shortPointer, &enc_bits); } In the mobile version of the software, compiled against the mobile build of Speech, I get 1 and 0 based on whether the speech is detected. In the version of the software compiled against the Win32 version of Speex,

Hello, I wonder if somebody has an idea what could be a reason behind this error message. I am running wine version installed as rpm for Fedora Core: wine-20041201-1fc3winehq. This actually happens for two games, one of them - fallout. I am able to run some windows apps with sound (flash player). Fallout displays initial screen and then crashes with this error message (apparently when it
