How to get audio data from microphone on pocketPC ?
Hi jere, thanks for this link, i'll see if i can do something good with that. speex.dll : ----------- I have a speex.dll which work, and i can encode and decode a wav file. (i used male.wav on speex.org for my test). But my dll is specific to my softphone. In fact i just include speex.h and i call speex functions for [en;de]coding. My code is based on speex website's sample :

How to get audio data from microphone on pocketPC ?
Hi, My name is Patrick, i am french, and i am developping a softphone for pocket PC using speex. Sorry in advance for my bad english. So i have make an GUI in C# that use the speex functions through dll write in C++. And the encoding and the decoding using speex seems to work not too badly.(i test with a wave file) My problem is that i need to get audio data from the microphone. In order to do

Fixed point bug in 1.1.6
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

speex_encode / speex_encode_int ... already sorry =)
Hi, i know this question has already been asked, i've checked mailing list logs but ... I didn't figure out the solution for my question. I want to use basic functionnality of speex, only VAD, no pre/post filter, even no VBR. But i *really* want to use less mem/cpu i can. So in which format should i pass data to speex_encode(_int) , float or short ? I quickly looked at the source code

speex_encode_int() - pls help..
Hi, I'm using speex 1.1.10 and writing a program similar to sampleenc. I need to use the fixed point library as I'm eventually porting to ARM processor but I encountered a problem with speex_encode_int(), which I used in place of speex_encode(). I gave it a short instead of a float (manual says it takes a short for the audio - 2nd parameter) but the compiler says it could not convert the

Samples per frame.. fixed or variable with configuration?
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

Re: 5. Re: how to build libspeex_armce.lib ? (patrick andrieux)
Hi Dave, I tried defining ARM5E_ASM and ARM4_AS, and you are right, it doesn't compile, But I can't say if the problem come from the Microsoft compiler, because if it doesn't know ARM assembly optimizations, who can know ? We may need to include/install something else to use ARM5E_ASM or ARM4_ASM, or maybe this part of speex's code is not finished. I tried to compare both

Just getting noise
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;

WaveIn/WaveOut and Speex
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

Linking issues (Visual Studio 2005 and libspeex.lib)
Hi, I've been doing some development for Pocket PC 2003 applications and have happened to chance upon Speex. To date, I've been having some issues in linking libspeex.lib with my application in MS Visual Studio 2005. Upon building my program, I will always receive the error: fatal error LNK1181: cannot open input file 'd:\Recorder\libspeex.lib' Recorder A brief description

Just getting noise
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) {

version 1.0.1 X 1.1.4
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

does installed lib support _int()s ?
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

Re: High pitched whine with Speex
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.

encoding speex, (insanity looming)
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:

Function call order on libspeex
Hello, I intend to make a speex port for freescale DSP56F800/E. I downloaded the source code, but I not realize which function are called in which order for encode after calling speex_encode (or speex_encode_int) and speex_decode (or speex_decode_int). Could anybody help me on this? Thanks in advance Alexandre Penna
