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

I'm only doing one frame using speex_encode_int greatly simplifies my code I'm not sure why the sample I was working off of was converting the shorts to floats then calling the other encode/decode methods. Based off of your suggestions I tried the following but I get the same result. virtual Enigma::u8* Encode(Enigma::u8* inputBuffer,size_t inputSize, size_t& outputSize) {

Alright noted, I changed me code so that the state is created in the constructor and destroyed in the destructor of the object. However I'm still getting the same issue although I'm sure that would have bit me sooner or later. The new code is as follows. virtual Enigma::u8* Encode(Enigma::u8* inputBuffer,size_t inputSize, size_t& outputSize) { short *in=(short*)inputBuffer;

Assuming one prefers to use the speex_encode_int() and speex_decode_int() when available, but fallback to speex_encode() and speex_decode() if an older version if the lib is installed, how does one best make the determination? The only thing I can see to do is call speex_init_header() and look at the result. Even at compile time it seems one must compile a test app that outputs that data and then

I'm having trouble with a Speex VOIP effort ... my first use of Speex. My development platform is Windows XP, but I intend to bring this up on OS X as well. At the moment, I send across speex frames (say 4 per packet... a configurable setting), and the settings of both encoder and decoder are simply fixed in code at the moment (wideband, short format input). I am fairly confident that I

Hi All, I'm very new to speex and in fact handling audio at all, it seems I have run in to a problem I seem unable to fix. I'm trying to take audio from a microphone using alsa, then encode it as speex and save to disk. I have been wondering if it has something to do with endian type, but speexenc and speexdec works fine. Currently I have the following setup: Platform:

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

Hi Tom, Thanks for your reply, I'm having a few difficulty's following you advise. You mention that I should be calling 'speex_encoder_int' & 'speex_decoder_int', I'm having problems finding these functions in the speex header. I am currenlty calling speex_encoder_init & speex_decoder_init in my test code, I have repeated the relevent bits of the example

Hi Jean-Marc, randoms, I've been playing with the 1.1.x api, more specifically modifying code to conditionally build against the 1.0.x api or the 1.1.x api. Code written for 1.0.x builds, with a few warnings, against 1.1.x. The major API change is of course that the type of PCM buffers has changed from float to int. This causes a few warnings related to speex_encode() and speex_decode()

Hi everyone, Our team is working on a realtime voice communication application. We are using openAL 1.1 to capture the samples and then encode them using speex. On the remote machine we decode the samples and play them using openAL again. Capture and play formats for the samples is AL_FORMAT_MONO16 and frequency is 22050. we are using wide band encoding/decoding. The encoding sample

I'm trying to use the speex API, and I think I'm missing something. I'm running on Mac OSX Tiger, and the attached microphone is a iSight. If I call the "speex_encode_int" function, and then immediately call the "speex_decode_int" function, shouldn't I get back the same data? i.e. in my example code, shouldn't the two arrays contain at least similar

Please compare samples: http://www.ivo.pl/ivo2/sound/krwawa_org.wav http://www.ivo.pl/ivo2/sound/krwawa_fixed.wav http://www.ivo.pl/ivo2/sound/krwawa_float.wav krwawa_org.wav is original file. Both output files was created using same program by compressing from wav to speex, then decompressing from speex to wav (using speex_encode_int and speex_decode_int). Only difference was used speex

This patch will export new speex functions in the generated library, such as speex_encode_int as well as the preprocessor, echo-cancellation and jitterbuffers. The ordinals used matches the 1.1.6 release from the speex.org website, so any new library created with this def file should be binary compatible with that one. -------------- next part -------------- Index: speex.def

Hi, Tank you for your reply. I have tried the sample programs given the manual and done encoding and decoding a wave file. That is working fine. I have already read the manual and API reference. But this problem did not occured with the wave file encoding/decoding. While capturing the data from MIC and encoding/decoding is giving this problem. Thanks and Regards, Vijender Reddy, -----

Changing from using floats to shorts did fix the high pitched tone problem. I'm having other problems but I'll look into it more first.

Hi, I am writing a program that should be able to compile using speex version 1.0.1 and speex version 1.1.4, but a I am getting some trouble to encode with one version e decode using the other. The program is taking care of the change in both speex_encode and speex_decode. The sample being coded or decoded has changed from float to short. To test it, I have modified the sampleenc.c that

This is going to take some explaining and I apologize in advance if any of this is found in the manual or sample code but I couldn't find it. I just graduated last may and this is my first experience with vocoders and dissecting a professional's code. I work for a company that is currently using a G729A vocoder from a 3rd party software company and is looking into speex so they no

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

hy, here is my speex encoder/decoder .. the sampleRate i use is 16000 and quality,complexity are at 5. can someone take a look in to the code and see if there is something that is making that robot voice here is a link to colored and numbered code, same as below http://barvanjekode.gama.us/temp/1257361243.html thanx. code ----------------------- #include "codec.h"
