similar to: C++ wrapper for speex

Ronald, I suggest we take this discussion off the list after this post. I don't see any problems with your code. However, I can make a few suggestions: 1) If you replace the lines: pSpeexHdr->lpData = (char*)pSound; pSpeexHdr->dwBufferLength = decodedSamples * sizeof(short); with: pSpeexHdr->lpData = lpHdr->lpData; pSpeexHdr->dwBufferLength = lpHdr->dwBufferLength;

hi Tom, i downloaded your speex wrappers and they'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

hi sirs, i am only recently studying speex and i'm looking for a C++ wrapper for speex that has higer-level implementations for the Encode and Decode functions, to sort of base my initial understaning of how the speex API work. i have in fact created my own, following on the instructions in the speex codec manual, but i havn't really made any positive progress. (a lot of people have

Hi, I am using the speex 1.0.4 library from Windows. I have posted my problem before but didn't get a solution. I am doing an VOIP project in which i am recording sound and streaming it to the peer. I wanted to encode and decode wav files that brought me to this site. I am recording sound in the following format:- m_WaveFormatEx.wFormatTag = WAVE_FORMAT_PCM;

Hi, I am developing a peer-to-peer video conference application which uses speex as a codec for the voice. I am new to speex, so please bear with me if I asked the obvious. After I added the encode and decode function to my MFC app, I heard a constant background noise, even when no one is speaking into the microphone. #define FRAME_SIZE 160 The application is coded in MFC C++. The record

Hi John, Thanks for your reply. Yes, my output device is in 8-bit mode, same as my input mode. I'm actually working in char (8 bit) arrays. Is it necessary to work in signed short integers only? I changed all the short arrays in the example to char. Carine ----- Original Message ---- From: John Miles <jmiles@pop.net> To: carineliang@yahoo.com.sg; speex-dev@xiph.org Sent: Thursday,

Hi, I've changed the m_waveFormatEx.wBitsPerSample for both record buffer and playSound buffer, changed my array from char to short and I'm still getting the same constant background noise. I notice that when I talk into the mike, I will get a slightly louder noise, can't hear any clear speech... Any idea what's wrong? Regards, Carine ----- Original Message ---- From: John Miles

Hi, I'm still unable to get rid of the background noise though I've changed the PCM samples to 16 bit. I'm began to wonder if I can just take the PCM samples and encode them. What my application tries to do is to record the voice from a microphone, encode it, send it via the socket to a peer, decode at the peer's side and play the voice. My application works fine without the

I wonder if anyone would have a comment on an experiment I have pretty much completed in my MFC/C++ project. With my simple libvorbis implementation, ogg decoding works just fine for files that are 10kb or larger. For anything smaller (actually, I don't have a 9kb file, so <= 8), it seems that I get an inaccurate value for ov_pcm_total. Though ov_read returns zero, I overflow the buffer

Hello, I tried to download the http://www.grandgent.com/tom/projects/tgAudioCodec/tgAudioCodec.zip link in this list but it does not exist. Where can I find it? If someone have it please send it again to list. I urgently need wrapper classes of Speex in C++ and Delphi. Please help me. Thank you.

I originally posted these classes because they turned out nice in my application, were reasonably generic, and I thought they'd be useful to other people. I figured it was a chance to give something back to the community. I eventually discovered that this was a bad idea and took them offline mainly for the following reasons: 1) Supporting the various versions of Speex is a nuisance,

I've been struggling desperately to get iGuidance 4 working with Wine and I've come across what seems like an incredibly specific problem. I've been struggling with the TTS output for the navigation, it just keeps randomly locking up the app, sometimes after a mile, sometimes 30, after figuring out I could debug just the wave classes, I think I've found a clue. It keeps hanging

Jean-Marc, Ok, I understand. It's floating point but I don't have a mechanism in place yet to capture the source data. I'll do that, reproduce the problem, and put together a minimal sample program that can reproduce it given a data file.

I have (finally) posted my Speex wrapper classes. They are at: http://www.grandgent.com/spx/tgAudioCodec.zip I followed your recommendations and they worked fine with 1.1.0. However, I'm still having the same problem with 1.1.7 that I had the last time I tried to upgrade. I'm using the same code with both versions, except for calling speex_encode_int instead of speex_encode, and

The 1.1.x Speex versions feature a denoiser that I'm a big fan of. It's adaptive and will filter out pretty much anything that is fairly stable over time while preserving the quality of the speech very well. You will need to make the following calls to set it up and use it: speex_preprocess_state_init speex_preprocess_ctl with SPEEX_PREPROCESS_SET_DENOISE speex_preprocess You can

I am using the denoiser and AGC, but the problem persists if I turn them off (stop calling speex_preprocess() altogether). Also, I have reproduced it on both a noisy system and a quiet system that hardly needs the denoiser. I know what you mean though, I have heard similar sounds when pushing the denoiser too hard. For example, doing 100x AGC, or trying to use an extension cord with my
