similar to: A question about speex_bits_write function

Thanks a lot for your explanations. Is it right I understand? if I've set SPEEX_SET_BITRATE to 16000(bps) this means that output is 16000/8=2000 bytes and I should set MAX_FRAME_BYTES and the length of cbits to 2000. Is it right? Maybe it is simple question but your answer is important for me, actually thanks a lot for your helps. Yasemin The last argument should simply be the size of your

Hi, I've attached a patch against SVN r14645 which adds GCC visibility information to all symbols exported from libspeex.so and libspeexdsp.so. It includes a configure.ac change to test that both the compiler flags and __attribute__((visibility)) works, and if so will #define EXPORT __attribute__((visibility("default"))) and if not #define EXPORT I've attached a diff output

Hello, I'm porting CELT 0.7.1 to an embedded platform and unfortunately (at least for me) CHAR is defined as 16 bits. I now got the vocoder compiling but when i compare the encoded output with a windows build, they don't match. Among the other problems i think that the char definition is one of the biggest players. I've seen in arch.h the following definitions: /* 2 on TI C5x DSP */

Greetings, I've just started porting speex to a TI C5509 DSP. It doesn't look like it's going to be too painful, but there are a couple of quirks about the C5x. 1) chars are 16 bits because memory addresses are for 16bit words 2) ints and short are also 16 bits (so sizeof(char) = sizeof(short) = sizeof(int) = 1) 3) the c5x is essentially big endian My plan is to change int and

I'm trying to use speex on OMAP's DSP using dsp gateway, and have some questions. The code almost works (within few next days I'll post a some kind tutorial and patches), but it seems to be a little bug in bits.c. The code looks like this void speex_bits_read_from(SpeexBits *bits, char *chars, int len) { ////////////////// bla-bla-bla /////////////////// for (i=0;i<len;i++)

Hi, Sorry! Marc Gimpel. I wrote it in a false thread before. It was my first time. :-) I have to write a small programm which should be able to record speeches and in addition synchronize the recorded speeches with measuring data. My idea is to record the speech in the normal way with speex and without ogg. If a sync message was received, i write a custom in-band messages using mode 13

Hi Jamey, Really cool to see Speex being ported to the C55xx and I'd be glad to integrate the changes required in Speex (and the style's fine with me). Here are a couple comments on the patch you sent (I looked at it, but haven't compiled). 1) The changes you made to the pack un unpack functions would only work if the 16-bit chars are "big endian" (relative to the two bytes

After searching the mailing list archive (I forgot to do that before posting, sorry!) I found the solutions: 1) The documentation has a mistake: The bit terminator is NOT set automatically! (I'm using the latest speex version!) It has to be set manually using speex_bits_insert_terminator(&bits); 2) speex_decoder_int() has to be called as long, as it returns -1. After that, all frames

To make it complete, here is the code that I am using to encode a large file: int __stdcall SpxEncode(unsigned char* inBuf, unsigned char* outBuf, unsigned int inlen) { //char *testFile; //FILE *ftest; //testFile = "test"; //ftest = fopen(testFile, "wb"); //fwrite(inBuf,1,inlen,ftest); //take every 320 bytes //copy every short to float

Hello! I was using Speex all the time, and I am now moving to Opus. I had encapsulated the decoder a bit, I had the following cpp file: #include "StdAfx.h" #include "spxcodec.h" #define MAX_FRAME_SIZE 2000 #define MAX_FRAME_BYTES 2000 CSpxCodec::CSpxCodec() : enh(1), rate(8000) { } CSpxCodec::~CSpxCodec() { } void CSpxCodec::Init() { speex_bits_init(&bits);

hello, i switched to use the encoder.processData() and encoder.getProcessedData() of jspeex. however it looks to me like a memory leak ... memory usage is increasing very fast and there is no visible stop ... after about five minutes java.lang.OutOfMemory occurs. I think it must be the jspeex component, because before i added jspeex to my app usage was constant at about 5mb. is it possible

Hi everybody, I have been examining on how I can use speex completely so I have one more question. I looked at examples and source code and it goes on. speex_bits_insert_terminator is called in speex_bits_write function. Shall I call this method one more time anywhere? Because in speexenc project, firstly speex_bits_insert_terminator is called then speex_bits_write is called when we assume that

Hello there, I thought I would contribute to this wonderful project but noting a simple but problematic bug in speex_bits_read_whole_bytes(). SITUATION: I have a large stream of frames with NO breaks or length indicators inbetween each frame. For this reason, I call speex_bits_read_whole_bytes() and fill it to MAXIMUM in a loop while calling speex_decode() until there are no more bytes to read.

Sorry, it seems I have only replied to Lakhdar, not to the newsgroup. Below is my reply to Lakhdar, and I would like to make it more clear now, using some pseudo values for simplicity: I read bytes 1 to 124 from my encoded spx file. I decode themt and get the values: ---Frame 1---- -293 -8234 2134 17 ---Frame 2---- -9323 -732 189 2329 Both frames are just perfect as I need them. But now when I

Hello Arnaud, You posted this question a long long time ago, however I found your answer so I decided to post it anyway in case somebody else have the same problem as you and me. You were actually very close in finding your solution. The function DoWritedbf is an internal function from the foreign package. To access it outside of the package just do: foreign:::DoWritedbf so in your line:

Hi SAITAMA Taro, I have been using speex-1.2beta1 dll in our voice application written with C#. In order to use Speex correctly firstly I advice to you examination speexenc and speexdec projects. I have used unsafe code and fixed statements in C#. I have added following method to library and I used that instead of speex_encoder_init simply. void *speex_encoder_init_new(int modeID) { const

Hi, I think what happened is that you did not write the "message" length. With user-callbacks, you also need to say how large the message. The size is in bytes and encoded in 4 bits. Besides, you're probably the first one to use user-callbacks. BTW, why didn't you want to use Ogg. It's much simpler to use and overhead can be made minimal anyway. Jean-Marc Le ven

It would be nice to have the following function added to the speex bits... void speex_bits_read_from_buffer( SpeexBits * const bits, void * const buff, const int buf_size) { bits->bytes = (char*)buff; bits->buf_size = buf_size; bits->nbBits = buf_size << 3; bits->bytePtr = 0; bits->bitPtr = 0; bits->owner = 0;
