(well, YMMV, but it got me 12% on Mac OS X Public Beta on my test case). In vorbis/lib/scales.h, add the following after fromdB() #define sqrt_fromdB(x) (exp((x)*.11512925*0.5)) In vorbis/lib/psy.c at the bottom of bark_noise(), do: < noise[i]=sqrt(fromdB(v)); > noise[i]=sqrt_fromdB(v); This avoids the sqrt() call entirely by just doing it as part of the exp(). (I'd

Excuse me, if the following is FAQ or nonsense, I'm new to R (and the list)! After trying to import a textfile of 184897 Bytes, R (v0.63.0 on Linux 2.0.35/DLD 5.4) gives the following error message: > read.table ("db.out") Error: heap memory (1953 Kb) exhausted [needed 150 Kb more] > Is there a possibility to increase

Hi all, The decoder is down 30% execution time, identical bit output. Didn't get the mdct yet; 1024 point mdct is a bit much to brute-force, and I'm not going to hand-unroll the whole thing either (the machine- unrolled version produced a 1.5M executable; understandably, it wasn't very fast. Still waiting for processors with 1.5M L1 code caches ;-) Slowest parts now are: -- mdct --

Well, here you are. 24k; sorry if I'm not supposed to put this size things in your mailbox, didn't know where else to put it. And you all are subscribed to vorbis-dev, after all. I'm not that good at breaking patches apart, so it's one big patch. Sorry. Overview: configure.in make profiling easier & more useful decoder-example.c (#if 0'ed) dither output;

Folks, If I have a series mm of, say, monthly observations, and a series dd of daily dates, what's a good way of expanding mm such that corresponding to each day in dd within the corresponding month in mm, the values of mm are repeated? So e.g., if I have mm: mm <- c(15, 10, 12, 13, 11) names(mm)<-c("Nov 2008", "Dec 2008", "Jan 2009", "Feb

In the old centos 4 we had cpuspeed and we could send a SIGUSR1 to it so the CPU would run at max speed. In centos 5 cpuspeed is not running. (although running with cpuspeed -C will go full speed) what is the correct way now in centos 5 to on the fly say run at full speed then sometime later tell it to drop back down? I have no process to signal any more. Jerry

Thanks for your help. My teacher advised me to use the "load_kld cpufreq" command and it resolved the problem. Tomasz Kowal

Hi list, I'm using C7 and noticed that cpu freq is enabled with governor conservative. I've used cpupower utils for governor change, but at the next boot it restart with conservative governor. I've tried also to start cpupower service and setting OPT in /etc/sysconfig/cpupower but it does not works. Can someone point me in the right direction? Thanks in advance

At bit-rates above 32 kbps, Vorbis tends to produce better results than Speex, even for speech. The only advantages of Speex over Vorbis at these

Hi, speex developers! I'm new to speex, and trying to build a simple echo application. something like this. microphone -> speex encoder -> speex decoder -> speaker I first test it the simple way, microphone -> do nothing -> speaker and this works fine. But when I try to encode speex, and decode it, it works, but some high frequency noise is added. How can I fix it? The

Hi, I've tried vorbis on a stream that has ~500Hz tops and it worked quite good, but the raw data was converted to a fake 16bit 44Khz WAV Are there any chances I can take the code and tune it to work with nonPCM data that has info from about 5 up to 500Hz? It would be nice to know where to start. Thanks you. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I request that the "freq" argument to hist be deprecated. Reason: One nice thing about SAS is is the consistency of certain inputs across many PROCs. In particular, they have "weight" and "freq" statements. We have added "weights" and "freq" to a number of functions in S-PLUS, listed below. I would like to see the same in R. In porting the

Hi, I don't understand what hist(x, freq=FALSE) does. At first I thought it would be just the relative frequencies instead of the absolute frequencies, by just computing "frequencies / n" in every category. But with a small dataset the y-values (densities) don't sum to one. Is there a way to get the histogram doing that? Or what is the idea of this density-computation?

Dear R-users, I am looking for a R function that would be the equivalent of the SAS proc freq ( http://support.sas.com/documentation/cdl/en/procstat/63104/HTML/default/viewer.htm#/documentation/cdl/en/procstat/63104/HTML/default/procstat_freq_sect006.htm). The table, ftable, xtabs functions are close but do not quite offer the same capabilities (e.g. they just return counts and no %ages as far as

Hi I'm sorry for the my trivial quest. I Have asterisk 1.4 with TDM 400 with FXO and FXS, and works fine from several months. Now I want to connect a device to TDMFXS that want a ring frequecy of 25 hz to activate: i am italian, and usually the ring freq is 20 hz. The other time (I have used that device several times with other asterisk installation) I have modified /etc//modprobe.conf and

Hi Everybody I need to create a lot of frequency tables with frequencies and percentages (and cumilative freq and % as well) for a report. freq() in prettyR give more or less what I need. I am trying to export the result of freq() to html but the html doesn't look look the console output. See the following example library(prettyR) library(Hmisc) x <- matrix(sample(1:3, 12,
