I have what R seems to consider a very large dataset, a 12MB text file of lat,long,and height values, 130,000 rows to be exact. Here's what I get: Thomas Colson North Carolina State University Department of Forestry and Environmental Resources (919) 673 8023 tom_colson at ncsu.edu Calendar: www4.ncsu.edu/~tpcolson

I'm looking for suggestions as to the best multimedia headsets for a call center environment. A few considerations: 1) USB headsets are preferable, because they don't require a soundcard. 2) Omnidirectional microphones are problematic, because they pick up too much background noise.

Hi, I plan to use AEC for a live performance, storytelling for very young children (and their parents!) in a mongolian yourte . Actually the storyteller can make vocal loops, there is an omnidirectional microphone in the center of the yourte, 5 loudspeakers in a circle along the yourte's wall and Pure Data in a linux box. And now she wants to make vocal loops over music and loops over loops... Maybe aec will help her? I did some testing on a small setup, 2 desktop loudspeakers and have very g...

Please see the code below. When I try to run the variogram - vg.deft<-variog(rd,uvec=10) I keep getting this error- variog: computing omnidirectional variogram Error in vector("double", length) : vector size specified is too large Also, when I try to define distance-based neighborhood - nb.tr=dist.neighbors(tr.locs,2) I get this error - Error in vector("double", length) : vector size cannot be NA In addition: Warning message...

Hi All, Some time ago I emailed this list and mentioned (as well as a couple of techinical queries) that I was trying to contact the PRS for information on the copyright licencing requirements of a non-profit on-line radio station, a few people expressed interest in this and asked I keep them updated. Well I just sent my third email (transcript below) informing them that I will assume a further

...lly based on the previous probabilities? I had also experimented with the 3GPP AMR VAD code (which is, of course, copyrighted) to see how it compares, and it was still better than speex, but speex is still pretty good. 3) denoising: This option was the most interesting. Previously, using an omnidirectional microphone, like that in a notebook or whatnot, to pick up speech gave a really poor SNR; conversation was possible, but it was quite annoying. With the speex denoising filter, it comes through really clear, pretty much as good as if one were using a headset and a directional mic right next to...
