Hi All, Need Help ! I am interested testing opus codec encoding decoding qaulity. for this have complied opus code codec from souce. After compiling i got opus_demo app. for Encoding i followed below steps: 1) Reference file used music_orig.wav (http://www.opus-codec.org/examples/samples/music_orig.wav) Number of samples : 4358219 (90.8 s) 2015-04-13 10:40:07 UTC Sampling

Hi JM, I am using narrowband mode with speex qaulity set to 0 and complexity set to 4. The code works fine on the 3.2GHz processor. The test program speexenc takes 7ms to encode 5sec worth of voice on the 3.2Ghz processor. The same takes 700ms on the ARM5E intel Xscale. The code that I wrote puts 10 speex frames in one RTP packet. When exexcuted on ARM I get lots of underrruns hence

Hi, First ,please excuse my poor English. Can someone help me on reading fortran binary object under R? I was trying to read mm5 data under R. However, I seem to stuck at reading fortran binary file storing met. data array. At the beginning, I used readBin() to read mm5 output directly with the following command. #mmout is a mmout file generated with mm5

Hi Sakharam, I see 2 potential issues with what you are doing. 1. ./opus_demo -e voip 48000 2 16 music_orig.wav testcase30.opus in above command, "16" for bits/sec seems too low. I'm no audio expert, but just cant convince myself you can get any reasonable audio data with 16 bits/sec. FYI, I was able to encode and decode with 16 bits/sec, but when I played the decode file with

Hi JM, Thanks for the earlier replies. I have tested it with quality 1,2&3 the result is not much different. Also I must tell you that I am using the armbe-linux-gcc compiler which does not suppoort arm5e-asm optimisations. I get lots of assember related errors. Is there any alternative? Will moving on to a board supported by arm-linux-gcc compiler ,to enable arm5e optimisation, help?

Monkey's Audio lossless compressor (currently win32 only, free but not open-source except decoder) author is thinking to implement a kind of audiophile-quality lossy compression which would filter "noise bits" that are hard to encode lossless but which are (or should be) inaudible and thus improve lossless compression (avg. 300-450kbps). I think that implementing something like this

Hi Can someone please help with the following, We are using asterisk@home 1.5 and SIP trunks to communicate to the PSTN network. We are having some problems with the call quality. Although we can hear the other person's voice quite clear when making or receiving a call, we get complaints from the people on the other end saying that our voices sound very unclear, low and that the voice

Wow, ok, whatever the problem is, I'm now pretty convinced that it's over my head. I am trying to setup samba as the PDC for our network. I cannot for the life of me get it to work. I went home, tried it on my laptop and it worked in 15 seconds. I came to work, setup the server exactly the same and...nothing. "The domain either does not exist or could not be contacted" blah blah.

Is there a setting that can be changed that keeps the screen from going black when changing between?

How do I install the DirectX-patch from Transgaming? I run the Wine that came with Mandrake 7.2. I've tried to run the patches in all the folders that has something to do with wine. I'm using "patch -p1 < wine-something". It just says that it couldn't find the file to patch. Mikkel Mastrup _________________________________________________________________________ Get

I have a new x3655 IBM and whenever the /etc/xen/scripts/network-bridge script starts, the ethernet would no longer work. This post isn''t about the cause, but the fix. I did a lot of tcpdumps and Googling, but I''ll spare you that. All they do is prove that yes, there is an issue. :) I tried Debian 4.0 i386/amd64 and Ubuntu 7.04 Server i386/amd64 and they all exhibit the

New installation seems to have behavior I cannot figure out. Here is illustrative sequence where I load a small data set (test) from Crawley's files and try to run a simple linear model and get an error message. Oddly, R reports that the variable 'test$ozone' is numeric while, after attaching test, the variable ozone is not numeric. Can someone please help? This behavior is

Hi just a quick inquiry Sorry if this is too trivial but I am just a beginner in R. I am looking at the plyr package and I am intrigued at how data(i.e. ozone, baseball) is loaded without having to type data(ozone). Are they automatically loaded when i call library(plyr)? I want to do the same thing when I make my package. How does one accomplish this? Also, are there any beginner guides on how

I want to estimate the effect of several independent variables on several dependent variables. In the example below I wanted to estimate the effect of three independent variables on ozone and temperature. My aim is to create a list of dependent and independent variables and automate the process rather than writing every dependent and independent variable in each model as I have done below.

Hello, There recommended range in Samba4 share for BUILTIN users is usually (from Samba wiki) # Default ID mapping configuration for local BUILTIN accounts # and groups on a domain member. The default (*) domain: # - must not overlap with any domain ID mapping configuration! # - must use a read-write-enabled back end, such as tdb. idmap config * : backend = tdb idmap config * : range = 3000-7999

I think I've gotten my Emacs/Sweave/R system set up correctly, thanks to Vincent and Jim, but I haven't been successful getting my first document produced. I'm trying to use one of Friedrich Leisch's examples, http://www.ci.tuwien.ac.at/~leisch/Sweave/example-1.Snw. I cut and pasted the text into a document sweaveexample.Rnw in Emacs. It seemed to be processed successfully with R:

Hello Given the following data for a data set called airquality. To identify the nature of the objects from the data set airquality example "Ozone" would it be best to use the command is. like is.character(airquality$Ozone) ....... I tried attributes(airquality$Ozone) but it came up null. Would there be a better way to identify these objects. Thanking you in advance for your

Hi! Where is ozone.xy? I've found ozone in package fields, but cannot find ozone.xy Actually, is there any way to find in which package lives a particular dataset (if the package is not installed in the local system?)
