similar to: speex_encode_int() - pls help..

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

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

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

hey guys, I just compiled an application similar to sampledec.c (for speex 1.1.10) and it was fine but when I executed it, the app exited without doing anything. I'm using MS VC 6.0 and this was all I got - First-chance exception in sampledec.exe : 0xC0000005: Access Violation. Has anyone encountered this / does anyone know how to deal with it? by the way, sampleenc executed perfectly... When

Hi All, I am a Speex novice but trying to use Speex in my Doctoral thesis. I installed Speex, was able to encode and decode files. Right now, I want to write my own cpp program that handle Speex-files. I tried to compile and run the two sample programs that come with the documentation (after having insalled the speex-devel-1.0.5-1.i386.rpm). However, when I compile. gcc sampleenc.cc Here is

Hi All, I am quite new to voice encoding and to Speex library. I have some programming questions that I am not able to answer even after having read the documentation (from the start to the end an from the end to the start) and by reading the sample code (provided in the documentation) and the speexdec.c and speexenc.c programs. I am currently working on an interface between Java code and

Hi Steve, thanks for the advice. I placed the appropriate functions outside the while statement but I still get this error at the while loop: First-chance exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. Unhandled exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. It looks like the same error. I've

Hi. I tried encoding a raw PCM file to Speex in my Windows Mobile device and it took about 45 seconds to encode a 10-second file. I had FIXED_POINT defined and used speex_encode_int. The device has an ARMV4 400 MHz processor. Question: Is this behavior expected or is it possible to encode speech to speex real-time such that I can record speech directly as speex in my device? What, if any, can be

I need to compile with version 1.1.4 because this is the one distributed with Mandrake 10 and it is my desire to let my application compile in this distribution and be compatible with other ones.

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

Hi, I am new to speex and I am trying to use the sample program given in the speex document. I have made some modification to that sample, so that input can be read from a file and the output can be re-directed to the file. I tried to encode an audio file using the sampleenc and decode the same by sampledec.c I am able to do it successfully, but when i try to play the output file from the

Thanks for the advice. With complexity=1, bit rates 5950,8000 and 15000 (CBR only), I'm still getting 30-50 seconds encoding time for a 10-second file. To anyone who has made this work in ARMv4, or knows how to, can I get some advice on the settings? FIXED_POINT is already defined in all relevant files. My source code is patterned after sampleenc and I haven't tried using Ogg.. my source

Hi all, I have just started playing with speex, and come up with the following code, which just encode a frame of 160 shorts, and the decode it. For some reason the decoded sample is completely different than the original one. is my code wrong? If so what? Or is it a reasonable which depends of values that weren't correctly set? Thanks, Andre #include <stdio.h> #include

Platform Intel Linux/Fedora Core 2 ALSA Soundblaster 128 PCI I am capturing U8 (unsigned 8 bit mono) audio from the sound blaster and attempting to compress it with speex. I have built and installed speex on the computer and can compile and link with no problems. I have the sample programs (sampleenc.c and sampledec.c) which I am following. The only difference is my raw data is in a char array

I always think short is better over float, because most of the time we don't get float form data, from, e.g microphone / wav files <p>-----Original Message----- From: owner-speex-dev@xiph.org [mailto:owner-speex-dev@xiph.org] On Behalf Of Conrad Parker Sent: Monday, April 26, 2004 12:58 AM To: speex-dev@xiph.org Subject: Re: [speex-dev] speex_encode / speex_encode_int ... already sorry

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;
