For those who are interested, I've run 3 EAQUAL tests on both the LAME and OGG encoders: LAME with the --alt-standard preset (with and without --nspsytune) and OGGENC (RC3) with -q 6 (my personal "sweet spot") I am somewhat unsure though about the validity of these tests, since the original and decoded files were not the same size (2...

I am but a poor code & compile illiterate, making it impossible for me to create Windows binaries from the EAQUAL source (http://sourceforge.net/projects/eaqual/). Would someone be interested in providing said binaries? They would be very helpful to me in evaluating Ogg Vorbis and other audio codecs. I'm also sure that other people would benefit from the program. -- GMX - Die Kommunikationsplattform im...

Well, this question comes once and again. I have RC3 and Garf's RC2 tuned versions (160 and 350) in a nice graph. Nobody should be surprised that RC3 is better, but in some cases GRC2 shows better EAQUAL/bitrate results. There seems to be room for improvement in RC3 with some tweaking. See it by yourself at http://audio.sinderman.com/ Cheers, AGS. <p>P.S. do not abuse the dynamic graph generator. If overloaded the machine will switch to a static pag...

I have run an ogg analisis using EAQUAL from -q 0 till -q 10 evaluating bitrate and quality. The results are shown in a nice graph, and can be seen here: http://audio.sinderman.com/ One thing I have found is a bug, as it is cleary shown by the blue lines. Other discoveries are written in that page, and others are still evolving in my m...

Hi, I just built a sample application with speex resampler in linux and I tried to resample 8K sine wave tone mono to 48k using speex_resample_process_int. I am using a tool called EAQUAL for audio quality. I find the quality of Speex resampler to be decreasing when I increase the quality q of the resampler init function. Can some one give me pointers regarding this?? As per the API, if the quality factor is increased, it is assumed that the quality should increase which is no the...

...em is that for each trial it gives me one text file (and I run between 30 to 50 trials at a time) and I would ideally like to merge all these text files into one large data frame with each column representing a single trial. It is not a problem if NA characters are added to make all the columna of eaqual length. Right now I am doing this by opening each file individually and cutting and pasting the data into an excel file. How can I do this in R assuming all my text files are in one directory. Is it also possible to customize the column headers. For example if I have 32 trials and 16 are experi...

...his application to the "tasks" file connected to this cgroup the threads belonging to this application will NOT be moved to the new group. Is it right? If so, is it OK? I mean, in the current implementation, threads created before the attachement of the parent process are not treated eaqually to those created after. Could you tell me if you know something about the rules of attachement of pid, or tid, to cgroups? -- what ID is OK to write to "tasks" file and what we can expect as a result? Tsuruta-san, how about your bio-cgroup's tracking concerning this? If we wan...

...in system(cmd, intern = TRUE) : 'unzip' not found Does it mean I have to install some special softwares for zip and unzip operation. Another question is whether ff always create physical files for vectors, I found when a ff ffdf object is created, the number of physical files created is eaqual to the number of data frame columns.

Dear all, I hope to remove a whole column from a data frame or matrix (> 2000 columns). All value in the column are same. The first thing is to select those columns. For instance, I hope to remove the V3~6 column, for all the value in those colume is zero. V3 V4 V5 V6 V7 V8 V9 V10 1 0 0 0 0 0.000 0.000 0.000 0.000 2 0 0 0 0 0.000 0.000 0.000 0.000 3 0 0 0
