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

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 s...

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 the audio buffer describes an audio sample using 8 bits. On the output side, WaveOut expects each Char to describe an...

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 sound when I try to Get PCM Char buffer fr...

Using speex_encode_int() might happen to work on your PC, but then going to a different platform, endianness might turn around and b...

...is 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 microphone is provi...

...or 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 that, i use the waveIn*** functions. When i record in a big buffer in *ONE* time, i can play the sound perfectly. (In this case, i only have one buffer and the callback function is not used) But if i record in a small buffer (160 char) several times, and i copy each time this small buffer in a big buffer, it doesn'...

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 instead of writing the speex strea...

...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 be happening? Additional info: Windows WaveIn/Out API is used to work with a sound device. The format is PCM 16 8 2 Thanks much, Dmitry

...> >I used padsp for a while when a beautiful project was born : WinePulse. I'm actually testing it with the main (and only) developer of this PulseAudio backend for Wine and recently he made it working on my Ubuntu 8.10 with PulseAudio 0.9.10. So it's not yet a full implementation and WaveIn doesn't work for me, but it will be fine and I hope integrated in Wine. Do you have a link to that DNS test with PA and OSS? Thanks, Susan Cragin
