ultra-low bitrate stream?
I am writing a long-run sound recording application using OggVorbis. The user can adjust sound quality parameter to make balance between storage space and sound quality. The input sound is 22050Hz, mono. To maximize the recording capability on a given storage volume, we want the result bitrate as low as possible. I use -q0 parameter and it produces a 32.0kbps stream. It is too high (our

[PATCH] Updating the ReplayGain documentation
In this topic on Hydrogen Audio(http://www.hydrogenaud.io/forums/index.php?showtopic=105586) someone asked a question about the sample rates that FLAC supports for ReplayGain. The outcome was that the current documentation of MetaFLAC is outdated since Commit http://git.xiph.org/?p=flac.git;a=commit;h=0554a4aee6966bc5b251364753ef85de72dfab19 because as of 1.3.0 FLAC supports Replaygain with many

[PATCH 3/5] resample: Add NEON optimized inner_product_single for fixed point
From: Jyri Sarha <jsarha at ti.com> Semantics of inner_product_single have also been changed to contain the final right shift and saturation so it can also be implemented in the optimal way for the used platform. This change affects fixed point calculations only. I also added a new fixed point macro SATURATE32PSHR(x, shift, a). It does pretty much the same thing as SATURATE32(PSHR32(x,

e1071 SVM, cross-validation and overfitting
I am accustomed to the LIBSVM package, which provides cross-validation on training with the -v option % svm-train -v 5 ... This does 5 fold cross validation while building the model and avoids over-fitting. But I don't see how to accomplish that in the e1071 package. (I learned that svm(... cross=5 ...) only _tests_ using cross-validation -- it doesn't affect the training.) Can

[PATCH] 02-Add CELT filter optimizations
Please ignore my previous mail and patch, there is a new version :). Patch changes are: - Use MAC16_16 macros instead of (sum += a*b) and unroll a loop by 2.

[LLVMdev] POST MORTEM: llvm-test changes
For the heck of it I tried upgrading to gcc 3.4.2 (from 3.3.3). It didn't make a difference. So here are the failures for llvm-test.

The C function getQ0 returns a non-positive covariance matrix and causes errors in arima()
Hi, the function makeARIMA(), designed to construct some state space representation of an ARIMA model, uses a C function called getQ0, which can be found at the end of arima.c in R source files (library stats). getQ0 takes two arguments, phi and theta, and returns the covariance matrix of the state prediction error at time zero. The reference for getQ0 (cited by help(arima)) is:

Currently there is a jump from 11khz (at 22khz

modifying a built in function from the stats package (fixing arima) (CONCLUSIONS)
Thanks a lot to everybody that helped me out with this. Conclusions: (1) In order to edit arima in R: >fix(arima) or alternatively: >arima<-edit(arima) (2) This is not contained in the "Introduction to R" manual. (3) A "productive" fix of arima is attached (arma coefficients printed out and error catched so that it doesn't halt parent loops to search for

Using Predict and GLM
Dear R Help, I read through the archives pretty extensively before sending this email, as it seemed there were several threads on using predict with GLM. However, while my issue is similar to previous posts (cannot get it to predict using new data), none of the suggested fixes are working. The important bits of my code: set.seed(644) n0=200 #number of observations

Qualified parameters in SOAP body using .SOAP
Hello, I am trying to reach a web service using the SOAP package. I succeeded calling the web service, but not sending parameters to it. After much research and tries, I think I found that the problem lies in the namespace including the parameters in the SOAP body. In short, my question is: how can I send unqualified parameters in the SOAP body of a call produced through the SOAP package?

Damn!
I just tried rc4-cvs and I can't believe how good it sounds! I can hear very little difference between the wav and the q0-ogg on my above-average stereo... It really makes MP3 look (sound) *pathetic* in comparision! I did some comparisions on a few songs, from noisy 77-punk to Jean-Michel Jarre to EBM/Industrial, and q0/~64kbit RC4-vorbis sounds as good or better than V9/~128kbit LAME-mp3
