similar to: Speex Encoding, Decoding - Access Memory Violation Issue in Windows Mobile

hi, I tried to encode the voice data read from AudioQueue and then decode it. There was nothing but rhythm left, it sounds like robot's voice, but I cannot recognize any word. The app was compiled by XCode 4.1. Speex 1.0.5 and 1.2.rc1 gave the same result. When compiling speex 1.0.5, I added them to Xcode project, set the Header Search Paths, then compiled successfully. When compiling speex

Hi ,I am new to Speex and exploring on it from last two days. I see everyone talking about it but can't get any help when I go for DLL. I tried to compile the source code of speex but didn't succeed as I am working in C#.Can anyone provide me the DLL or link for DLL for Windows mobile so that I can proceed.Regards,Swapnil -------------- next part -------------- An HTML attachment was

Hi all, i am not criticizing the technology itself, but the fact that from the point of view of the implementator that need to make a technological choice while selecting a codec to be used for a mobile multimedia application, speex does not provide affordable informations on "supported platform". Without arranging a test bed with a lot of devices and spending a lot of money i

Dear all, i am currently evaluating which codec to be used for a "very narrowband" voice communication system (using either VoIP either GSM CSD) on mobile devices running Windows Mobile and Symbian OS. I had experience in using AMR-NB 4.75 with VAD on Symbian OS and all worked very well. However, AMR it's not royalty free and if i need to use it on Windows Mobile i will need

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

Hi, I got the following problem with speex. Could you help me to resolve the following issue. Description: I am taking speech input from MIC storing in a buffer after that i will encode by using speex then decoding and sending to output(speakers). it is small demo project of speech encoding/decoding in VC++. I am reading the data from buffer in the following way where data is short[] type and

Hi, i am using squid as a transparent proxy. i have added this 3 lines to my rules file ACCEPT $FW net tcp www ACCEPT loc $FW tcp 8080 REDIRECT loc 8080 tcp www - !192.168.100.2 i want to limit the number of connection that are made from every pc on the network to the proxy server. if i change the 2nd rule to ACCEPT loc $FW tcp 8080

Hi Tom, Thanks for your reply, I'm having a few difficulty's following you advise. You mention that I should be calling 'speex_encoder_int' & 'speex_decoder_int', I'm having problems finding these functions in the speex header. I am currenlty calling speex_encoder_init & speex_decoder_init in my test code, I have repeated the relevent bits of the example

Hi. I trying to encode PCM16 8000Hz stereo data to speex and put it into the .flv file format. But at the output I can hear only noise. What I doing wrong? Here is the code: void main() { SpeexBits bits; void *enc_state; int frame_size; int quality = 10; char cbits[MAX_FRAME_BYTES]; FILE *fin, *speex; short input[MAX_FRAME_SIZE]; int nbBytes; int channels =

hi all, I can claim that our hotfoon service has run millions of mobile voip minutes using speex on mobile and desktops. it works! earlier you needed more powerful cpus (until the integer port), however now the cpus are much faster and the code complexity is much lower. my only regret is of not being able to write some demo apps for speex on win mob. I will surely deliver it in june to settle this

In short try calling speex_encode_int and speex_decode_int. The calls to speex_encode and speex_decode expects the data to be a floating point values. The data is passed by pointer and the compiler does not do the conversion. This is why you are getting the segfault on decode as the short is 16-bits and a standard float is 32-bits.

how many calls can I make to speex_encode_int before calling speex_bits_write? Can I stuff 10 frames? - farhan

Hi, as per the shorewall MultiISP documentation ( http://www1.shorewall.net/MultiISP.html ), it says "Use of this feature requires that your kernel and iptables include CONNMARK target and connmark match support (Warning: Standard Debian™ and Ubuntu™ kernels are lacking that support!)." it means MultiISP wont work properly if i am using Ubuntu server. if yes whats the

I'm trying to use the speex API, and I think I'm missing something. I'm running on Mac OSX Tiger, and the attached microphone is a iSight. If I call the "speex_encode_int" function, and then immediately call the "speex_decode_int" function, shouldn't I get back the same data? i.e. in my example code, shouldn't the two arrays contain at least similar
