...y're really what i'm looking for! i really cannot worry about container support at the moment because i'm working with real-time audio, and hopefully toward VoIP when everything else is in order. im using waveform to capture data from the microphone. the raw PCM sample is stored in the WAVEHDR structure's member lpData, and this variable is of LPSTR type. if you have the time, can you please check on my test code below and see where i could be having problems with. (this is the handler that processes captured audio) LRESULT CRecordSound::OnSoundData(WPARAM wParam, LPARAM lParam) {...

...high traffic, so I desided to use speex for compressing the data. I'm recording with mono, 16bit/sample, 8000 samples per second. I tried to add the speex compression, but I always get a crash when I try to decode the data. Here is my encode and decode function: int audio_encode(char dest[],WAVEHDR *source,int srclen, int quality) { SpeexBits bits; void *enc_state; float input[160]; char output[200]; unsigned int i,n=0; int compr_length = 0; unsigned short length; speex_bits_init(&bits); enc_state = speex_encoder_init(&speex_nb_mode); speex_encoder_ctl(enc_state,SPEEX_SET_Q...

...ne it and i supposed i could do it also, but i'm really confused now with all my failed attempts.) i'm particularly interested with real-time audio and i have an event handler that captures audio samples like the ff: void CRecordSound::OnSoundData(WPARAM wParam, LPARAM lParam) { LPWAVEHDR lpHdr = (LPWAVEHDR) lParam; if(lpHdr) { WAVEHDR* pSpeexHdr = new WAVEHDR; BYTE * pSound = new BYTE[lpHdr->dwBufferLength]; memcpy(pSound,lpHdr->lpData,lpHdr->dwBufferLength);...

Hi all, i have just finished my installation of wine as normal user (see below). Notepad is running fine, so i decided to run something more fun, starcraft. The installation program works, even with sound and all, exept when i decide to run the previews. The previews run rine, but whithout sound. When i return to the installation program the sound is gone. But anyway, it does it's yob,

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

...= 0; m_WaveFormatEx.nSamplesPerSec = 8000; m_WaveFormatEx.nBlockAlign = 1; m_WaveFormatEx.nAvgBytesPerSec = 8000; The recording is as follows :- When the buffer(size = 2000 bytes) gets filled with sound data a function with the body shown below is called. LPWAVEHDR lpHdr = (LPWAVEHDR) lParam; if(lpHdr->dwBytesRecorded==0 || lpHdr==NULL) return ERROR_SUCCESS; ::waveInUnprepareHeader(m_hRecord, lpHdr, sizeof(WAVEHDR)); Here lpHdr->lpData contains the audio data in a character array. Now here I want to use Speex codec for encoding the data so...

...speex. as the mic and the speakers are built into the laptop, an echo canceller is required. what i am doing is this : First, each time i finish writing a block to the waveout, i copy it into a buffer like this: Segment *pseg = (Segment *)phead; waveOutUnprepareHeader(waveOut, phead, sizeof(WAVEHDR)); memcpy(remote, pseg->samples, 160 * sizeof(short)); Second, each time i get samples from the mic, i do the echo cancellation like this: if (nsamples == 160){ speex_echo_cancellation(echo_state, (short *)pseg->samples, remote, unechoed); q = unechoed; } I have also initialize...

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 sure (and still am) how to translate the Char*...
