hello guys this is my code for the C# wrapper. ================================= using System; using System.Runtime.InteropServices; using System.IO; namespace Speex { ///<summary> ///the following class is the win32 SPEEX API that retrieve ///methods and structures from the libspeex file ///</summary> public unsafe class Speex_win32 { #region Speex Constants //global speex

Hi All, I am trying to cross compile speex-1.1.12 to powerpc-405, i get a error after the make, speexec.lo error, please help me how to get rid of this error.

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 have read the message below, http://lists.xiph.org/pipermail/speex-dev/2006-October/004924.html and try to use P/Invoke to use speex in C#. This is a part of my code. [StructLayout(LayoutKind.Sequential)] public struct SpeexBits { IntPtr chars; // "raw" data int nbBits; // Total number of bits stored in the stream int charPtr; // Position of the byte

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

Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM. I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper

After a long processing, I was able to create a version of a small C# class that was able to emulate the rproxy by P/Invoke. This is mostly to find a workaround a performance problem of the StatConnector. It's almost work but ... I have strange memory exception when I call the print function. The variable seems to not survive from one call to the other. As there is no debug symbol for

Hi, There is some additional work to do (close lsa handle), but the far the code below is working. Let me share it with you in case somebody will have the same need that me. br Vincent LE TOUX using Microsoft.Win32.SafeHandles; using System; using System.ComponentModel; using System.Diagnostics; using System.Net; using System.Runtime.InteropServices; using System.Security.Principal; namespace

hi all, i'm new to speex and i'm stuck on a problem. I have a buffer that holds 5 seconds of audio data, sampled at 16000 hz and quantitized with 16 bits pcm. I only want to encode it with speex and then decode it and write it back in the same buffer. no compiling errors and no errors during runtime, but from the sample of 5 seconds only a short noise is all I get. I hope you have any

At just a first quick glance, I'm pretty sure that you don't want to be creating and destroying the speex encoder/decoder with each frame. That's supposed to stay the same for more-or-less the entire session.

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,

I'm completely new to speex and I'm having issues adding it to my application. I can pass raw PCM and that works fine so I know my transmission code is fine however when I try to encode/decode using speex I get noise almost like a whining/buzzing sound. I'm sure it's and issue in my code but I'm not sure where to start looking other then my gut tells me I'm not sizing or

Hi Rafael, > 2) add a "byref" mark in the pointer argument. I think you mean "bycopy" or "byval" here. > 3) Have llvm-gcc create a copy before calling the function. Don't forget that the function may be called by code that was not compiled by LLVM. That's why we have to pay attention to the ABI! Solution (3) supposes we have control over both

Hi, Guys I am starting looking the source code of Speex. Maybe a little silly, but I can not find the implementation of the function speex_encode(). Only something like below void speex_encode(void *state, float *in, SpeexBits *bits) { (*((SpeexMode**)state))->enc(state, in, bits); } Does that mean some of the detail implementation is embedded in lib without source code? I am new in

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) {

Hi all, i've to encode voice from a voicemodem. I choose speex 1.0.5 for its quality in voice encoding. I've tried to implement an encoder but unsuccesfully. Here's my code: /* ============ SPEEX stream ENCODER ============================================ */ int SPEEX_EncodePCM(struct _IDA_ClientSocket *IDA,char *buffer,unsigned char *PCM,int num_samples) { /* buffer point to the

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;
