[PATCH] Check for _WIN32 instead of WIN32 in preprocessor checks
_WIN32 is always defined by the compiler automatically when targeting that platform, while WIN32 only is defined automatically in some configurations, and e.g. in MSVC only ever is defined in project files (if at all). Some other checks in the codebase already check for both WIN32 and _WIN32; those are left untouched. --- include/speex/speex.h | 2 +- libspeex/stack_alloc.h | 2 +-

Just getting noise
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.

Just getting noise
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

Just getting noise
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,

Problems with Speex Libary
today I try to compile a test-file from the Documentation. I link the libarys correct but have only one error in this line: state = speex_encoder_init(&speex_nb_mode); The error: main.cpp|21|undefined reference to `speex_nb_mode'| The linking libarys: "libspeex.lib" "libspeexdsp.lib" I am assuming you are doing this in Windows. You need to change the

Newbie - Encoding PCM
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;

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) {

libspeex.dll
hello, we start to develop an open source project. This project is a VoIp application with the same features like "Teamspeak" (http://www.goteamspeak.com). Our test application run in peer to peer mode under windows 2000 and above. At the moment we are using the gsm codec (13 kbps bandwidth). Later there will be a port for *unix systems. As aforementioned the project will be released

GCC/ELF Visibility patch
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

Speex in VB .NET
Hi there, I have searched what seems like everywhere and was unable to find a .NET wrapper so that I can use speex in VB. I did find a speex.NET.dll but this didn't seem to work on what I needed. I therefore decided I could just use DllImport within VB .NET and create my own unmanaged links to libspeex.dll. With the help of this partial c# code

encoding -> decoding doesnt work
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

using speex in C#
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

speex_nb_mode declaration problem
Hello all, I am using the speex APIs in a gnuradio block. I used the similar code as in the sampleenc.c/sampledec.c which works perfectly fine. My compilation does not give any error, but when I run the python test, it complains that speex_nb_mode is undefined. I tried to declare it explicitly then it as const SpeexMode *mode = NULL , then i get an error that i cannot initialize the const
