Frequency and Phase Spectrograms
I know that there is a function, (spectro3D), that produces the Power Spectrogram. Are there R functions that produce the Frequency Spectrogram and the Phase Spectrogram? Thank you for your time. [[alternative HTML version deleted]]

Display an image defined on a polar grid [SEC=UNCLASSIFIED]
Dear R-help, I have a matrix of data values specified in polar coordinates, i.e. (r,theta). I know that I can transform this image to Cartesian coordinates and then use image to display the results, however, I want to display the image as is, without any coordinate transformations. This would require displaying individual "pieces of pie" colour-coded by their data value. A comparable

[LLVMdev] Is LLVM expressive enough to represent asynchronous exceptions?
Is LLVM expressive enough to represent asynchronous exceptions? --------------------------------------------------------------- Summary: Need new LLVM instructions or extending of all instructions. C++ exceptions are synchronous: the compiler knows when/where they are being raised. Asynchronous exceptions can be raised at any time. For example, an integer divide-by-zero may raise an

Help with a permutation test
Hello List and thanks in advance for all of your help, I am trying implement a permutation test of a multinomial logistic regression ('multinom' within the nnet package). In the end I want to compare the parameter estimate from my data to the distribution of randomized parameter estimates. I have figured out how to permute my dependent variable (MNNUM) x number of times, apply

Antw: Re: OPUS vs MP3
Hi guys, as MP3 and Opus have very similar objectives, I think the original poster's question was a valid one: Why does Opus have more artefacts in the lower frequency ranges than MP3 has? The spontaneous suspect that lower frequency artefacts may be more noticeably than higher frequency artefacts seems plausible, also. Is it a matter of energy (which is higher for higher frequencies)? When

Prosodic/phonetic analysis with R
Hi Folks, I'm interested in looking (in a beginner's amateurish way) at prosodic/phonetic analysis of recorded speech. In particular I would want to use R to formulate and evaluate specific models. So I would like to ask R people for their recommendations for a program which would a) Take as input a sound file in one of the common formats (".wav", ".au") b)

lmer with only random effect
Dear all, I want to fit a random effect model with only one random factor. I do not want to include the intercept term either. The model I using now is lmer(values ~ (1|lot), data=tmp) The results are as below. How do I take out the intercept term? Or if this is not possible for the lmer function, is it possible using lme function in the "nlme" package? Thank you very much in

Opus Tools -- low bitrates, new features in 1.5, "expect-loss"
> Why are you using a stereo file > containing the same sweep in both channels > and then downmixing to mono? When I first tried encoding at a higher bitrate, I needed to test the different behavior of the "mid" (l+r) and "side" (l-r) channels. That's why I made the first sweep identical on both the left and the right channel (i.e. "side" is silent)

OPUS vs MP3
Just to be clear, my goal here wasn't to make fun of anyone, but to drive the point that spectrograms should *never* be used to demonstrate quality. The only case where they can sometimes be useful is for diagnostic purposes. If you hear something and you're not sure what you're hearing exactly, then sometimes a spectrogram can help you figure out what it is. That's pretty much it.

[LLVMdev] RFC: How to represent SEH (__try / __except) in LLVM IR
Moving this month old RFC to llvmdev. Not sure why I sent this to cfe-dev in the first place... --- Based on code review discussion from John, he thinks filter expressions should be emitted into the body of the function with the try, rather than being outlined by the frontend. Instead of having the frontend create filter functions, we would use labels in place of typeinfo. The IR would look
