similar to: Speex VAD&denoise algorithms on TMS320C6713

Hi all, What are the steps to get Vorbis running on a TI C6713? I know I should use the floating point code, but am unsure what files I should compile in Code Composer Studio. Specificially, I am using the TMS320C6713 to receive Vorbis through a manufactured UART Daughter Card and output raw audio through its audio jack. Thanks for your help, Matt Hutchinson -- Matt Hutchinson Rice University

Respected Sir/Madam, I am working as Research Scholar at IIT, Bhubaneshwar, which is one of the pioneer educational organization in India. ( http://www.iitbbs.ac.in ) My assigned task is to transfer voice signal (Audio in future) over wireless sensor network. I have Arduino DUE, Arduino Mega, TMS320C6713 DSP board, TMS320F28379D Lunch pad, FPGA boards and necessary Microphone, filter, amplifier,

Dear all, I have been using Speex during last year over PC with very good results. Now I'm trying to move my code to the DSP TI C6713. It's the first time I work with a DSP and with Code Composer. I use speex quite well but I'm not very good at compiling for different platforms. After reading all manuals I tried to compile the speex library with Code Composer and the speex options for

Hello, I'm using Speex1.1.11.1 source code. I enabled dereverb by speex_preprocess_ctl(). I try different dereverb_level and dereverb_decay values and it seems to not work. I generate some test files in CoolEdit using reverb or echo and then preprocess it by speex_preprocess(preprocess, input, NULL); and output is the same as input:(. Denoising and VAD works very good. I tried dereverb with

Yeah, I am familiar with this library, but as I know this is just for sources. I am more interested in requirements clients have to meet, what header response options are available, and

Given the use of random salts, you would have to generate (number of possible salts) rainbow tables. This drastically changes the CPU/storage tradeoffs. >

Hi I have been developing an audio application using Speex. To reduce the background noise in the captured audio I have enabled the denoise feature and set the noise suppression level to 60. Although the constant background noise is reduced but using denoise introduces a weird effect in the audio which can be described as 'Drain Pipe' effect. Has anyone faced a simiar issue with the

Hi. There is denoise for preprocess during encoding. The nature of my source is unpredictable and sometimes the result is better off if I dont have denoise ON when I save my encoded speex file. So, I would like to implment a real time denoise during decoding/playback time, (instead of having the denoise result saved into speex-encoded file). Is there such denoise-preprocess function that runs

Hi, I just downloaded http://www.speex.org/download/speex-1.1.4.tar.gz and tried to build it but the file denoise.c seems to be missing from the archive. Can you fix this or is it better to get everything from cvs? Another question, when will a stable version of 1.1 be released. I'm interested in the preprocess features but I would also like a stable encoder/decoder :-) Best regards, Chris

Hello, when I call my conference, I see this error in my logs: ERROR: Function DENOISE not registered here is snippet from extensions.conf ... same => n,Set(CONFBRIDGE(user,announce_join_leave)=yes) same => n,Set(CONFBRIDGE(bridge,record_conference)=yes) same => n,Set(CONFBRIDGE(bridge,record_file)=/home/asterisk/file.wav) same => n,ConfBridge(1000) same =>

Hi All I am using speex in one of my WinCE project. I have been trying to use speex to perform denoise on the captured audio packet and echo cancellation. Following behavior I have observed while using various options. I would really appreciate if you could help me with the issues I am facing. 1. Denoise: I have written the following to code to perform denoise. //To initialize speex

Hi I am trying to use the Denoise option of speex but unable to do so successfully. I would really appreciate if some one could help me and identify what exactly wrong i am doing... I am using below code to perform denoise. //Initialize speex preprocess state and set the denoise option int nEnable = 1; SpxPreprocessState = speex_preprocess_state_init(160, 8000);

Hi Jean Thanks for the reply. We expect to use the codec in an environment where we expect very high background noise where high noise suppression will be needed. In a situation like a soccer match. Is there a way of retaining high noise suppression and still getting better audio quality. Your pointers will be of great help. Thanks, Gurinder On 6/4/10, Jean-Marc Valin <jean-marc.valin at

You're using Windows, right? The project file is simply out of date. The denoise.c file has been renamed to preprocess.c > Another question, when will a stable

I meant "not knowing how speex's VAD works", of course, not VAD in general. If you would stop interpreting everything I say in the least charitable manner, this might be going more smoothly than it is. (Tom was right, by the
