similar to: noise when passing trougth speex_preprocess

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); }

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

Hello, i want to use speex out of visual basic. So i have written a few wrapper functions in VC++ (v6) wich i can call from VB (v6). But i have problems with the encode and decode functions. Encode wrapper Function: I want to copy the value of an single array in VB to a float array in C which can be encoded. And the output of the encoder have to be unsigned char because in VB its an byte

Hello, all. 1) ACE does not work for me I am in a voip project using Speex, failed to have hte Speex ACE work. here is how I initialize it: /** * Configurations : * #define BITS_PER_SAMPLE (16) * #define SAMPLE_RATE (8000) * #define CHANNEL_NB (1) * #define DURATION (20) * SPEEX_MODEID_NB */ _eco_state = speex_echo_state_init(_encframe_size, 10*_encframe_size); speex_echo_ctl(_eco_state,

I have IceCast 2.3.1 running on Window XP SP3 as a windows service. My computer is behind a d-link router, and the router is configured to pass through to port 8000 on my computer. On the same computer I am running WinAmp with an oddcast dsp and streaming work fine, people beyond my router can listen no problem. I also have a laptop running Windows Vista SP2 with WinAmp and a Spacial dsp,

Hi I am running the icecast ver 2.3.1. I am trying to get the video working but everytime I try to view the video and audio ( http://localhost:8000/different.ogg) , I can only get the audio no matter how I try to access the stream ( quicktime,VLC, cortado java applet ) the only thing I get is audio. I am running the server in a Red Hat Linux enterprise 4. Any help will be appreciated ezstream

Hello, I'm trying to compile linphone 3.0.0 in Ubuntu And I'm getting the following compilation error. I somewhere read that the fault happens because of the gcc 4.3.2 that debian based linux uses. Is there any solution (except downgrading gcc) Thank you in advance if /bin/bash ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include/ -I.. -I../../oRTP/include

Hi, I am trying to get speex_preprocess in real time for Arm. Tried 32.32 fixed point but looks like even that precision is also not enough. Any suggesions?

speex_preprocess() isn't covered in the manual, is it? But, it's very easy to use. If it returns non-zero, voice was detected.

As I understand it, there are two separate ways to get VAD information from Speex: 1) Using the encoder. 2) Using speex_preprocess(). I present the following observations from an application developer's perspective. They may be wrong, in which case I would appreciate corrections. - The two VAD systems are implemented differently. - speex_preprocess()'s VAD provides more accurate

Hi, While most of the native functions take float[] array as input, why the function speex_preprocess(...) can only accept short[] array? How do I call this function if I have float[] array inputs? Do I need to convert the floats to Integers back and forth? Thank you in advance. Long Deng -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi,all I do some work on ARM cpu with VS2005, speex1.2beta. I use the FIXED_POINT define and it works well of codec and decode. but the speex_preprocess() still cannot work real time. I look into the soucecode , and didn't find any fix-point #ifdef computation . So I wish there should be some fix in the future version. If you already done the similar, pls tell me , thanks! Fan

I would like to use speex_preprocess() for voice activity detection. I read the comments in speex_preprocess.h and the relevant paragraphs in the Speex manual. Is there anywhere I can find more information on how to use this function?

Hi Marc, As I understand it, this represents the peak amplitude you want the AGC to aim for. If you look at preprocess.c, you'll see that this should be a float from 1 to 32768, with the default being 8000. I've been using 70% of the maximum in my application. You should probably experiment to see what works best for you. Tom Marc <maarcc@gmail.com> wrote: > > Hi.

I was wondering if is there any way of plotting line segments on a plot. Actually I need a graph that shows the advantage of using a different method for estimate the parameter of my databse, so I've plotted the N estimatives for M areas in my database and then I've plotted the new estimation (N' estimatives) and I need a line to link those paired points (N'(1)-N(1),

Hello, all. I am delightfully slogging my way through installing and configuring Asterisk 1.6.1.1 on CentOS 5.3. I'm learning lots and admiring the product but I'm having a problem getting speex to install and I would very much like to use it. It is not available in menuselect and the problem appears to be with speex_preprocess_ctl: [root at pbx01 asterisk-1.6.1.1]# grep -i speex
