SPEEX tech specs
Thank you Jean-Marc.
My understanding is that G.729 is a telephone
codec, so there must have been some reason why
its developers went to 10ms/frame. Do you know why that might be?
From a recent post on this list I saw somebody
talking about your decoded sample rate being
8KHZ/sec. and then he mentioned that being 160
bytes at 20ms/frame. That said, I take it that
your decoded samples are

SPEEX tech specs
Thank you. You're right ... my error ... I meant
to say 12 bytes (including the 2 bytes for VAD).
And it is 10ms/frame. No matter ... thank you for
the SPEEX specs. In terms of quality, what SPEEX
bit rate compares with G.729 at 8kbps data rate
please? Is there some reason why you chose the
20ms frame rate? Do you keep that same frame rate
for the different bit rates? The faster frame

arithmetic and logical operators
Why, in R, does (0.1 + 0.05) > 0.15 evaluate to True? What am I missing
here? How can I ensure this (ostensibly incorrect) behavior doesn't
introduce bugs into my code? Thanks for your time.

Scripting issues
Users,
I am currently running scripts on a rather large dataset. Many times I sort
the data into smaller datasets and must analyze them individually. My
instincts are to make a for loop, but I can't seem to find a way to index
each sub-dataset (data frames as the case would have it). I would make an
array, however, the data types of the columns are different and as I
understand, an array

Array dimnames
Dear all,
Possibly a rudimentary question, however any help is greatly appreciated. I
am sorting a large matrix into an array of dim(p(i),q,3). I put each entry
into a corresponding matrix (1 of the 3) based on some criteria. I figure
this will assist me in condensing code as I can loop through the 3rd
dimension of the array instead of generating 3 separate matrices and using
the same block of

Print Summary
Dear All,
I am currently working on a project involving a rather redundant task. I
have 11 files that I will be generating anova tables and plots for. I am
contemplating writing a for loop to process each file, create an anova
table, the appropriate plots, and save them to my hard drive. I've included
pseudo-code below.

SPEEX tech specs
Hello Jean-Marc:
How many bits do you have in a frame please and what is your frame
rate? For example, G.729 (ACELP) has 12 bits/frame including VAD and
the frame rate is 100/second ... I'm looking for the comparable
figures for SPEEX.
Thank you.

unzipping with ff
I've noticed that ff uses the unzip utility available on it's host OS to
load datasets via ffload. It seems to work fine in linux, but when I try
to use the package in Windows (hence dling Windows unzip utils) I get 2
errors, one telling me that the options aren't being passed to unzip
correctly and another indicating that my filename is incorrect. First,
does anyone know of an unzip

compressed audio tutorial - "major" update
I've made a large update to the introduction to compressed audio. I
completely rewrote the first section, which I wasn't happy with. It now
features two diagrams (worth 1000 words each!), and is broken up into a
couple of sections.
http://cs.leander.isd.tenet.edu/~mitchell/vorbis_intro.html
I have also continued to tweak other sections based on feedback from email
and this forum.

Beta upgrade (could not find a decent answer yet)
Greetings All from Florida.
As of tonight, Sunday April 14th, 07, I finished loading the dvd iso
of 5 beta (or 4.92 as it is shown to be) and went archive diving to see
what was up with the updater not finding the 4.92 files on the mirrors..
I only saw a few notes about removing a dev file and something else,
then a comment about removing an image file, then a comment about
not doing it in X as

Haven't done formal testing and it depends on whether it's G.729 or
