Hi all, i use speex preprocessor features in this way: =================================== #define NN 160 /* 20msec di audio */ ... int tbc=0,c,d,ret; spx_int16_t TEMP_Buffer[NN]; char DLECODE; /* Inizializza il preprocessore Speex se non inizializzato */ if(Modem->speex_pp_state == NULL) { Modem->speex_pp_state = speex_preprocess_state_init(NN,AUDIO_SAMPLERATE); }

Hi all, as in subject, speex_preprocess inject noise in my data. Someone can help ? Here's the way that i'm using: #define NN 160 /* 20msec di audio */ #define AUDIO_SAMPLERATE 8000 spx_int16_t TEMP_Buffer[NN]; speex_pp_state = speex_preprocess_state_init(NN,AUDIO_SAMPLERATE); c = denoise; speex_preprocess_ctl(speex_pp_state, SPEEX_PREPROCESS_SET_DENOISE,&c); c = agc;

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.

Hi, in my application i quite often (not allways) get those two warning: "Invalid mode encountered: corrupted stream?" "Invalid wideband mode encountered: corrupted stream?" The stream is not corrupted but i wish to know what those warning mean to correct my code. My encode and decode routines are those (libspeex 1.1.4): SpeexBits enc_bits, dec_bits; void *enc_state,

I'm trying to build the MySQL components in asterisk-addons but no luck so far. I hope that you can help. I have MySQL installed. rpm -qa indicates: MySQL-server-5.0.22-0 MySQL-devel-5.0.22-0 MySQL-client-5.0.22-0 rpm -ql MySQL-devel | grep client indicates: /usr/lib/mysql/libmysqlclient.a /usr/lib/mysql/libmysqlclient.la /usr/lib/mysql/libmysqlclient_r.a /usr/lib/mysql/libmysqlclient_r.la

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 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:

If by webchat you mean anything interactive, then I can already tell you what the problem is. TCP+Ogg. For anything real-time, you want UDP/RTP without Ogg. Also, you need to take into account the fact that computers do *not* have accurate clock and their soundcards drift. None of these problems are fatal, but you need to take that into account in the design. Jean-Marc On Mon, 2006-08-07 at

I'm currently working on a speex + theora webchat. I have both working alone, but to make them work together and to know where the package goes, I'm trying to use ogg packages. With theora there has been no problem, but with speex I can't make it work. The problem is that for a second it works great, but then it begings to gain lag, and in a little time it has 5-10 lag seconds (into

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''m working to patch actionpack/lib/action_view/helpers/ cache_helper.rb so that it doesn''t throw when ouput_buffer isn''t ActionView::OutputBuffer but is still html_safe. In 3-0-stable the function contains the following if: if output_buffer.is_a?(ActionView::OutputBuffer) safe_output_buffer = output_buffer.to_str fragment =

hey I am able to do: block_func(x, y) do .... end But if I try to do this: form.block_func(x, y) do .... end I get an error like this: syntax error, unexpected '')'' @output_buffer.concat " "; @output_buffer.concat (( form.block_func(x, y) do ).to_s); @output_buffer.concat "\n" Any ideas? thanks

sorry, no webchat, is a videoconference program. And I'm using UDP as you can read down on the mail. The problem is that speex packages alone work great, but to split speex/theora packages on the arrive I need to use some kind of container, and I'm trying ogg.

Hi, I read in the documentation something about how to realize packing more than one encoded frame into a packet. Before I read this, I always encoded every frame seperate and packet them as following together: [encoded length][encoded frame][encoded length][encoded frame]... But if I understood the docu correct, it should be easier: I call speex_encode_int() for every frame until the whole

Hi All, i need your help in determining the problem in the following sample code (taken from speex manual) for fixed point encoding. i tested encoding a 160 sample frame and then decoding it back But The problem is that the decoded frame is totally different from the original frame(see output below).What is the possible reason for this?.thanks for any help #include<stdio.h>

I'm working on an application where I need to record the current playing position and return to it later. and I need this to be done the most efficient way, so I used ov_raw_tell() and ov_raw_seek() because the documentation says they are the best when speed is a concern. but the problem is that sometimes ov_raw_tell returns the same value before and after calling ov_read; here's an

The example in the documentation demonstrates using speex_bits_reset before encoding and decoding each frame. " speex_bits_reset(&bits); speex_encode(enc_state, input_frame, &bits); nbBytes = speex_bits_write(&bits, byte_ptr, MAX_NB_BYTES); " What happens if this is not done? I think I'm missing the point of having a SpeexBits object.
