Re: nice idea
Agreed that the oversampling isn't useful in the long term. I'm not sure what you mean by 'dictioniary overhead'. I'd like to see an easy-to-invoke set of parameters that will spare no cpu expense and produce the tightest theoretically possible output. I'm guessing the best of Marco's idea can be achieved by adding heuristics to dynamically determine optimal frame

nice idea
some times ago i was playing with coding, shannon theoremes and other stuff, i have tried without success to compress audio wave, and i have notice that simply oversampling audio material enacnhe a lot compression ratio i only take awav file, oversampled it by 20 tiimes and then compressi it using pkzip or rar. i don0't remember if i also do a CONSTANT PREDICTION, iony know that pkzip and

Sporadic Issues
The problem is not icecast streaming, its trying to stream through a browser. It is very complicated to do. Each browser has it quirks depending on OS, version and what other audio programs that are installed. Having the external player link should resolve the issues. We gotten from using a browser player to letting the customer choose there fave audio player to use :) Even this has cause

Creating new instances from original ones
I have a question about data mining. I have a dataset of 70 instances with 14 features that belong to 4 classes. As the number of each class is not enough to obtain a good accuracy using some classifiers( svm, rna, knn) I need to "oversampling" the number of instances of each class. I have heard that there is a method to do this. It consists in generating these new instances as follows:

status of CRAN
Dear List the other day, I had my yearly staff interview with my Head of Department. Under my list of publications, I included a document which I wrote (R-and-octave.txt) that ended up in the "contributed docs" section of CRAN. Unfortunately, neither my HoD nor the personnel person were terribly impressed with it, even though its preparation time was commensurate with many of my (co

Sporadic Issues
Hi I think a part of your story was not clear : - You talk about an "upgrade" , it's an upgrade of icecast ? the OS icecast is running on ?

NA in logical vector = data frame row numbers scrambled
Dear all. RE how to estimate parameters of multimodal distribution Thank to prof.Ripley for pointing me to mclust package, although I am not sure I can apply it to my problem. I have another question. I need to change some of my values in data frame to NA. I use something like df[df$v1 < 5, 5:10] <- NA which is OK if there are no NA values in v1. here are some foo attempts >

Sporadic Issues
Hi, I help run an NPR/PBS station. We were running ice cast before our most recent upgrade. However after the upgrade we have now been receiving sporadic reports of people being unable to connect. The only confirmed issue is with Saffari on Windows. We are working on that specific one. But I've also received sporadic reports from users on chrome, firefox, mac, and windows and various other

REALTIME and VARIABLES
Hi, I'm having some problem with realtime: let's say I have a dialplan like this [globals] IPPHONES=_3XX [sip] exten=>${IPPHONES},1,Answer A call from ip phone 300 comes in, and it's been answered. Then I "switch" the sip context to realtime, putting the exten in the db and using the variable name for this as in the file version. [globals] IPPHONES=_3XX [sip]

rpart results - problem after oversampling
Hi all, I am trying to predict a target variable that takes values 0 or 1 using the rpart command. In my initial dataset I have few positive observations of the target variable; therefore I have oversampled the rare event by a multiple of 6 (i.e. from 762 to 4572). However, in my results, I end up with a number of positives in one of the terminal nodes that is not divisible by 6. As I have the

Efficient way for multiplying vectors with a only certain number of rows in a matrix
Dear R-users, I am working on a problem that I am currently not able to solve efficiently. It is about multiplying one column of a matrix with only a certain number of rows of another matrix. Let me illustrate my problem with an example: n.obs = 800 n.rowsperobs = 300 n.param = 23 Designmat = matrix(rnorm(n.obs*n.rowsperobs*n.param),ncol=n.param) Betamat =

Moving to ORCv2 - Where are my global constructors and destructors?
Heyho, Recently I tried out the ORCv2 JIT, especially the LLJIT. I gotta say, that I really like the new interface and the way you use it! However there is one thing I'm missing. I wrote a small bit code file, which should force having a global constructor. int wuff(); __declspec(noinline) int miau() { printf("Huhuhu"); return wuff(); } const int x = miau(); When I

Support for ultra-high sample rates?
Hi. I was wondering if there was any interest in extending the flac container format to support sample rates above the 655k current limit. Please note this is not for using ridiculously high sample rate sourced audio for some imaginary audible benefit. I've been involved in some experimentation with offline upsampling in software prior to delivery to an external DAC as a way to bypass the
