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

The following patch allows memdisk to support compressed floppy images created by WinImage. WinImage creates a PKZIP-style archive with a single member, the .img (or .ima) file containing the floppy image. WinImage names such archives with a .imz extension. This patch lifts the header/trailer checking code from gunzip() to a new function, check_zip(), which both checks for a valid ZIP image and

Hello, I encountered some unexpected behavior of unzip when using info-zip's unzip instead of R's internal program. Specifically, unzip("file.zip", list=TRUE, unzip=/usr/bin/unzip) produces incorrect output if the zip archive has filenames with spaces, and results in an error if the zip archive includes an archive comment or file comments. Here is some code to reproduce along

I'm still stuggling with files left open. My app is a Dialogic application on a Win2K box. The host is running AIX 5.1 ML2 and samba 3.0.23a. Whenever my PC app speaks a prompt stored on the AIX box, the file stays open. smbstatus, fuser and lsof all agree the file is open. All other apps that I've tried, Winzip, pkzip, vi, etc., behave properly. I just can't believe this is a

No. I want the tightest possible compression, while remaining 100% compatible with the subset that all known FLAC decoders can

I don't think you guys should worry too much about messing up old decoders, but no matter what you choose to do FLAC MUST REMAIN LOSSLESS.

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

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

Greetings- I am in the process of constructing a nonlinear model using nlme. The model is attempting to fit a nested data structure from some public-opinion data (the data are from individuals nested within organizations). The question I have is fairly simple (I hope). The data were collected in two stages: a 15,000-subject randomly-sampled telephone interview (the SCREEN), with 2,517 subjects

Hi, I often have to do this: select a folder (directory) containing a few hundred data files in csv format (up to 1000 files, in fact) open each file, transform some character variables in date-tiime format make into a dataframe (involves getting rid of a few variables I don't need concatenate to the master dataframe that will eventually contain the data from all the files in the

Hello All, I have all the packages as .zip files in a folder, say zipfolder. Does "pkunzip -d c:\zipfolder\*.zip", while I am in the library folder of R home, install the packages just like installing each package individually from the RGui Packages menu?

In species distribution modeling where one uses a large sample of background points to capture background variation in presence\pseudo-absence or use\available models (0\1 response) it is frequently recommended that one weight the data so the sum of the absence weights is equal to the sum of presence weights so that the model isn?t swamped by an overwhelming and arbitrary number of background

The Wine development release 1.3.23 is now available. What's new in this release (see below for details): - Support for stubless COM proxies on x86-64. - Builtin dxdiag now outputs real information. - Monochrome bitmap format in the DIB engine. - Beginnings of a true shell Explorer builtin. - A number of new D3DX9 functions. - More support for Indic text shaping. - Various bug

No. If you want such things, try TAK, OptimFROG, Monkey's Audio or even LA, you'll lose hardware compatibility anyway and they do much better than FLAC will with a -9 option. FLAC 1.0
