Packet loss concealment ??
Hi,
I would like to know which method uses Speex to conceal the loss of packets. I've reviewed the code and haven't found anything.
Thanks in advance.
Iago Soto.

Fixed-point version
Hello list
I'm joining the effort to port speex to a fixed-point version, but as
I'm a physicist used to deal only with floating point numbers (lots
of them), I have no practice in working with fixed-point versions of
such numbers.
For instance, in the first source I'm trying to work with, nb_celp.c,
it is hard to see that the following two lines of code yield the same

Plans for tighter integration of reference classes in R.
Hello Everyone! Here are a couple of thought/questions on refClasses
integration in R core functionality.
First, coexistence with S4:
> X <- setRefClass("classX", fields = c("a", "b"),
+ representation = list(c = "character"))
> x <- X$new()
> x at c <- "sss"
> x
An object of class "classX"

Monty on holiday
Hi folks,
My wife and I are taking a long weekend to celibrate our anniversary. I won't
be around again until Wednesday to answer email or do anything else on Vorbis.
Yeah, I know, I usually answer my email once a month anyway (so likely no one
would notice me being gone), but just so folks know if anything really juicy
comes up :-)
I'll be merging my latest branch with mainline

frame size in speex
Dear Speexers :-)
I am trying to change the frame size from 20 ms to 10 ms, I did that by
changing the value of the frame_size from 160 samples, to 80 samples in
the sampleenc.c file. The number of frames increased as expected, but the
size of the encoded stream of each frame remain the same! For example, if
I use quality mode # 8 (corresponds to 15 kbps), the encoded streams size
in bytes equals

nutdrv_qx interface change proposal item_t::preprocess
mmh..
At the moment there are 3 distinct preprocess functions that operate
on 2 different types:
- info_rw_t - preprocess();
- item_t - preprocess();
- item_t - preprocess_answer().
For info_rw_t: range/enum values are preprocessed just to see if that
specific value is to be used or not depending on the conditions the
driver meets at runtime (e.g.: low voltage devices -> low voltage
ranges).

Adding robustness to Speex on wireless networks.
I've not so much bandwidth to add channel coding but i've few bytes to spare for error detection. With a polynomial CRC-8 i've already more than 99.6 % to detect a burst error in a frame.
So let's suppose the critical fields of Speex are:
Wideband bit
Mode ID
LSP
OL pitch
OL pitch gain
OL Exc gain
So my plans are to calculate a CRC on these fields for each frame i send, then if i

SAMBA eats up all memory...
Hello,
I am running SAMBA 2.0.7.0 on AIX 4.3.3.0
I have a 1 Tera Byte filesystem on AIX made available to NT and MAC.
There is heavy IO activity on this filesystem and all of a sudden the NT's
and MAC's can't read or write any file on this shared filesystem.
Also AIX is running out of memory whenever this happens and files cannot be
copied onto the said filesystem even at unix

audio preprocess questions
Jean Marc,
I have been fiddling around with preprocess to try to get it sounding
less metallic/underwater- so based on some things said recently,
I have been first fiddling with mean_post and mean_prior to try to
get them to do change the update rate, so that update_noise gets
called at the right times.
Haven't made it too deep into the code, but I have a few
questions in speex_preprocess:

Possible fixed point overflow/div 0 preprocess.c
Hi,
I'll try to keep this as brief, yet descriptive enough to save everyone
some time.
If I'm off with this one please forgive me, but it has fixed my issues.
I am not
sure whether it is just my compiler (gcc 3.3.5) doing the wrong thing
with the cast.

Speex preprocess & loudness
Hi,
Does someone know if I could use SpeexPreprocessState::loudness or
SpeexPreprocessState::loudness2 to create a VU meter. And if so, how?
<p>Thanks,

speex preprocess redux
Jean Marc,
Thanks for the advice. The estimate update may come in handy.
I have had some time to play with the adaptation time. I tried
making the adaptation time 80, 160 and 320. It seemed like
the smaller value was actually the best in my initial testing,
but I need to test this against a more noisy setup than I have here.
I am guessing that for vad a shorter adaptation time is probably

nutdrv_qx interface change proposal item_t::preprocess
Hi and thank you for your effort.
You are very close to what I want to achieve, but I was already aware of
the impossibility of querying direct from a command. I wanted the
following (both would be covered by your changes):
1. preprocess an item_t in the direction: NUT->DEVICE
in order to be able to support queries like ups.generated.yesterday

speex preprocess redux
Steve,
The main problem I am having with the system is clipping off the start
of someone's speech when they first start talking- the ends of the sentences
seem to be handled properly. I am wondering whether this is the fault of the
audio playback system or whether this is a speex issue-
I also get the musical artifacts problem with the denoiser. This seems to
be more of a problem on open
