similar to: Failed rsync -- two different files considered up to date

Has anyone else experienced high CPU usage when using RSYNC in windows 2000 server? I am using the rsync.exe (and applicable DLL's) from the cygwin installation (I am not however running cygwin on this machine). The linux machine connecting to the windows rsync daemon has a very low performance hit when the session is running (see below). However, the windows machine, which has a much

Hi, I have a setup that rsyncs (using the rsync protocol without rsh/ssh logins) from one windows server (A) to a NAS (B) via a second windows server (C) (A is on a separate location from B & C, and the NAS doesn't support rsync directly), where C stores data on an SMB share on B. My problem is that I often get "No such host or network path (136)" from rsync (robocopy or

Dear Rsync Users, Please can I have a bit of rsync advice? I am trying to rsync a file called. 'Draft text - with Holley comments.doc' from machine a to machine b. Unfortunately this isn't working because I think rsync recognises the - character and thinks it's an option. I have tried escaping this out as well as putting it all in " " but neither seems to work

If more than one speaker receives the *same* signal, it doesn't matter the number of speakers. It only gets tricky when the speakers are playing slightly different signals (e.g. from a stereo song).

The reasons I have posted these questions are: 1) To find out if Speex can take advantage of SIMD extensions. 2) To maybe learn from someone with previous experience in optimizing Speex for moderns x86 architectures before I set off trying all kinds of things on my own.

I actually forgot to mention that I'm using ultra-wideband mode, but seems like you understood that anyway. Is this true that Speex echo cancellation only performs well in narrowband mode !? I've been using 100 ms as the default tail length. I don't know what the ideal tail length would be. I have tried shorter and longer tails but it hasn't made any difference. Does

First of all, thank you for your input Tim. That is very helpful. I would love to hear from other people with experience of AEC and Speex. I guess I have to split my question into to parts now. 1. Is it a fact that using the windows multimedia API (wave audio) for audio capture and playback makes it impossible to do echo cancellation with Speex AEC or other EC method due to inprecise timing? I

Hello I'm using the package ade4 to obtain classification from a .txt file. I use the following commands: cronquist <- read.table("cronquist.txt", h = T, row.names = 8) cronquist <- as.taxo(cronquist[7:1]) cro.phy <- taxo2phylog(cronquist) in which cronquist.txt is a file with a classification of 218 genus of tree species from french Guiana. We I try to use the

I believe there is a documentation error regarding speex_preprocess_ctl(preprocess_state, request, ptr); The manual states: SPEEX_PREPROCESS_SET_DENOISE Turns denoising on(1) or off(2) SPEEX_PREPROCESS_SET_AGC Turns automatic gain control (AGC) on(1) or off(2) I noticed that setting a value of 0 turns the setting off. Setting a value of 1 or 2 turns the setting on. While I do think 1 and 0 is more

I have a question about the overall performance of Speex and what I can do to improve it. I'm running Speex Windows x86, Visual C++ EE compiler. I will say right away that I've only compiled debug so far and used no compiler optimizations at all. I use the uwb-mode, preprocessing, denoising and echo cancellation. I've noticed that speex consumes a lot of cpu resources. When I run this

hy, recording and playback is working perfectly without speex. i have try to set samplerat from 6000 to 441000 and quality from 1 to 10 sam with complexy, but the best i can get is with 16000 samplerate, 5quality and 3complexy .. but still, the voice that came out is annoying, artificial, robot ,...

I'm trying to understand a bit more about the inner workings of the speex resampler. I want to do resampling on a voip stream. High quality and low latency is important. 1) What does speex_resampler_magic() do? 2) I find that resampling has quite an impact on performance and I'm trying to figure out where the cpu cycles are going and see what can be done to reduce the cost. I ran a profile

Hi! I'm having a bit of a problem setting up an rsync operation between two Windows 2000 servers. On one of the machines I have started an rsync Daemon (service, started as administrator) using the lines below. On the other machine I do a rsync -Pzrtvpo /cygdrive/d/root/Folder administrator@192.168.2.4::root What happens is that all transferred files (no problem with the actual transfer)

I'm trying to install libguestfs on Debian squeeze installed from http://people.debian.org/~bengen/libguestfs/ It does not work. Here are the details: I was able to install libguestfs-tools and its dependencies. However, aptitude removed the following two packages: qemu and qemu-system. I'm not sure if it's okay or not. If I try to install those packages back, I get the

If you define _USE_SSE, CELT is already able to use SSE instructions. You must be careful on Windows though because it doesn't support C99 var-arrays and alloca() isn't properly aligned for SSE, so you have to

Well, I am not the person to be asked about how Speex AEC works :) And I was referring speaker input as having direct access into what has been played thru speaker. (ASIO Soundcard provides interface for that) So if I am remebering correctly, with data from Mic and Speaker in sync, speex AEC should do the job.

Ok, let me be more clear on this. AFAIK, Windows OS doesn't expose speaker input as other OS ( Linux, Mac OS...). That puts you in bad spot in using Speex AEC with windows. Only way to work is to use Soundcard with ASIO functionality which does give you speaker input. But then you would have to impose that requirement on all your users. I heard Speex AEC works great from developer who
