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

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

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, I read in the documentation something about how to realize packing more than one encoded frame into a packet. Before I read this, I always encoded every frame seperate and packet them as following together: [encoded length][encoded frame][encoded length][encoded frame]... But if I understood the docu correct, it should be easier: I call speex_encode_int() for every frame until the whole

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) {

Hello, I'm having a problem using Speex - I'm getting white noise/static from the following process: (Load File) -> (Encode) -> (Decode) -> (Play) I know there's no issue with the loading or playing because (Load File)-> (Play) plays the file properly. I believe the problem lies with the speex_bits_write and speex_bits_read_from functions, because if I change my encode

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

The way I do this is to compute the number of frames (by dividing the size of my input by the number of bytes per frame and then calling speex_encode_int() that many times. Something like speex_bits_reset( &bits ); for( n = 0; n < num_frames; ++n ) { speex_encode_int( enc_state, (int16_t*)input_tail,

Simple questions:1. when this method is called for each frame, do I have to call them twice for both the encode process and the decode process?2. does preprocessor do preprocessing on raw PCM data or on encoded speex data? I need to clarify this because i want to know when should I call this function, before the encoding process (i.e. preprocess the pcm data) or after the encoding process (i.e.

hello, i try to add a speex compression on the TDM Talkthrough on the BF-533 EZ-KIT LITE but when i compile i obtain the following errors: [Error li1021] The following symbols referenced in processor 'p0' could not be resolved: 'speex_bits_destroy [_speex_bits_destroy]' referenced from 'Debug\Process_data.doj' 'speex_bits_init [_speex_bits_init]' referenced from

hi, I tried to encode the voice data read from AudioQueue and then decode it. There was nothing but rhythm left, it sounds like robot's voice, but I cannot recognize any word. The app was compiled by XCode 4.1. Speex 1.0.5 and 1.2.rc1 gave the same result. When compiling speex 1.0.5, I added them to Xcode project, set the Header Search Paths, then compiled successfully. When compiling speex

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.

Hi I am facing a strange problem. I have integrated speex codec's narrowband mode in my SIP based server. Then I tried to integrate the wideband mode. But the program crashes mysteriously. My encode and decode codes for wide band mode are exact similiar to that of narrowband, except the mode initialization, where I put "speex_wb_mode" instead of "speex_nb_mode". My

i don't think so. this is my current code: for(i=0; i<samples;i++){ /*only get max 320 bytes at a time so bits can handle*/ Client->raw_audio[i] = *input++; Client->temp_audio[i] = Client->raw_audio[i]; Client->session_File[ndx] = Client->temp_audio[i]; ndx+=1; } speex_bits_reset(&ebits);

Hi, what is the good way to encode / decode multiple frames in packet ? I read that I must do multiple call to encode and thats it. But when I'm trying to decode,, it doesn't work. Maybe, the problem is my decode function. Here is my encode function void ms_speex_enc_process(MSSpeexEnc *obj) { .... Do I need to increase gran value to 640 or read / encode (2 times)

Hi, I have one rtp packet with multiple frame inside e.g 6 speex frames. I packed those frames manually by concating them into a buffer(memcpy at certain array index). Then at the other side, i decode them in a while loop using speex_decode_int(), and hoping that this function will decode one frame at a time. But when i inspected nbBits, it seemed all of 6 frames decoded at once. I guess the

Hi all, I have a problem when I am encoding (or decoding) stereo audio. With mono data, things are fine and everything works without any problems. When I try to decode stereo data, all I get is a static sound - similar to that of a radio not tuned to any specific station. I wonder what might be wrong? Below is the code, first, of the encoder and next that of the decoder. Any information or

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,
