Previewing oggvorbis files in GNOME...
Hi. I'm wondering if anyone out there can give me a little help trying
to figure something out: I presently am running CentOS4.1 with GNOME as
my desktop (It runs quite well, I must say!). I just have a little
curiosity: I have a few audio files (.wav, .mp3 and .ogg) and I like to
"preview" them. When run my mouse over the .wav files (and mp3 files)

How to evaluate an lm() object for generating warning statement in a function
Hi, there
I tried this post on R-help but did not generate any replies, so I thought
I might try the waters here since it's a more programming-based group.
I have written a function that will allow me to calculate the variance
components for a model II (random effects) single factor ANOVA (perhaps
this is
me re-inventing the wheel, but I handn't yet come across anything in R that

Questions regarding OPUS_APPLICATION_AUDIO vs OPUS_BANDWIDTH_NARROWBAND
I have an audio device whose 'driver' gives me Opus encoded frames using
OPUS_APPLICATION_AUDIO and max bandwidth set to OPUS_BANDWIDTH_NARROWBAND.
How does Opus encoder decide the center point of the 4K bandpass filter?
Is it done frame by frame?

adaptive bandwidth
Thanks Dragos,
I assume I will be setting those parameters during initialization of
encoder right?
Question is, if connection gets too lossy, how will opus adapt to it? Can
it automatically shift bitrate down to minimize impact?
Mark from IRC suggests that the app has to be aware of the losses and
change it on the fly.
Has anybody on the list tried this?

bandpass filters in R
Hi,
does anybody have any ideas regarding the easiest and most efficient way
of implementing a bandpass filter in R ?
any help would be truly appreciated.

Do you refer to any particular version of c++filt? I tried, but seemed
not to work. For example, when I run a command as below:
c++filt _ZNSt4listIiSaIiEEaSERKS1_
The output remains the same as the input symbol.

Combining 2 columns into 1 column many times in a very large dataset
*Combining 2 columns into 1 column many times in a very large dataset*
The clumsy solutions I am working on are not going to be very fast if I can
get them to work and the true dataset is ~1500 X 45000 so they need to be
efficient. I've searched the R help files and the archives for this list and
have some possible workable solutions for 2) and 3) but not my question 1).

Designing and incorporating a digital filter
I have a time series of data from an electroencephalogram (EEG).
I wish to filter the data to get rid of 50Hz mains 'hum'. I have
'designed' a combination bandpass and notch filter using a web-
site. The site returns the filter in "ANSI C" source code. It is:-

[LLVMdev] C++ Mangled Names
I have encountered a need for manually generating the mangled name of an
arbitrary C++ function. The only way I currently know how to do this is
to generate a dummy C++ source file, compile it, and look at the
output. This approach is so ugly that I would like for it never to see
the light of day. The c++filt tool generates demangled C++ names given
the mangled ones, which is the opposite

OPUS encoded data size and bandwidth of encoder
Hey, I am having trouble with the size of the encoded bytes by Opus. I am
also having issue with the Bandwidth ctl.
Here is the scenario.
If I encode 16khz sampled audio:
opus_encoder_ctl(enc,OPUS_SET_MAX_BANDWIDTH(OPUS_BANDWIDTH_WIDEBAND))
opus_encoder_ctl(enc, OPUS_GET_BANDWIDTH(&x)) = 1102
opus_encoder_ctl(enc, OPUS_GET_MAX_BANDWIDTH(&x)) = 1103
average encoded size = 120 bytes
