Hi Jean-Marc,
yes, problem exists in narrowband-mode, too.
I already twiddled with max_gain, but did not have real success. I changed line 337 of ltp.c (function pitch_gain_search_3tap_vq)
if (sum>best_sum && gain_sum<=max_gain) {
to
if (sum>best_sum && gain_sum<max_gain) {

Hi Jean-Marc,
dBFS means dB relative to digital full scale. In other words: a sine value of -42 dBFS will, on a 16 bit PCM signal, swing between 131 and -131 only (16384 * 10^(-42/20))
So we are far below +/-8000.
At the moment, I'm out of ideas how to debug systematically. That even very small rounding errors alter pitch values fundamentally makes the situation worse for me, because it

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
O.k., some more info:
I just tested bandwidth widening to fix this. But I need to go to gamma values below 0.9 to become stable -- clearly too much widening, I think.
I looked inside the Levinson-Durbin algorithm next. The lines
#ifdef FIXED_POINT
r = DIV32_16(rr+PSHR32(error,1),ADD16(error,8));
#else
r = rr/(error+.003*ac[0]);
#endif
look interesting. While for floating point,

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi again,
I tested lower cumul_gain limit values. In fact, I reduced the value to 240000, 230000, 220000, ..., 20000, 10000, 5000, 2000, 1000, 500. (quality 7, complexity 2)
For input signal 2000 Hz, the values 190000, 130000, 60000, and 1000 look o.k., all others don't. For 500, the (zoomed out) waveform shows some kind of amplitude ripple -- i think, this value is definetely too low.

Hi Jean-Marc,
I'm currently trying to analyze the LPC synthesis filter. For this, can you please tell me the exact format of the LPC coeffs (in variable interp_qlpc), please?
cheers,

Hi Jean-Marc,
do you have any other ideas what to look for? Or do you currently debug yourself? As I already wrote, I'm out of ideas...

Xen on Intel i7 Nehalem?
Hello,
i´ve got a new Intel Nehalem server with an i7-920 CPU.
I installed a Debian Lenny OS ...
Now, i cannot find any images for hypervisor or kernel that seem to be runable on that hardware.
:-O
All of that is AMD:
apt-cache search hypervisor

Find the three best values in every row
Hello,
i have a dataframe with the GDP for different Country (in the columns) and
Years (in the rows).
Now i want for every year the best three values, if possible with name of
the countries (columnnames).
For the best it's no problem but for the other two values.
Thanks,
Alfred

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
What happens if you change that line:
if (cumul_gain > 262144)
to use a smaller value? What value works OK (if any)?
One more thing, when things go wrong, do they eventually go back to
normal or does the codec never recover? It's unavoidable that the audio
goes bad for a short period of time because of the long-term predictor.

Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi Jean-Marc, all,
I didn't get any response to my issue up to now and would like to now if anyone can reproduce this behaviour and if there is some idea what happens. I am willing to fix this issue, but because I do not know the internals of speex, I need some advice on how to proceed...

Hi Frank,
Sorry, I *do* care about the problem and just happen to be overworked at
the moment. What I suspect is that the pitch gain gets close enough to
unity that the loss makes it bust. Did you test with the floating-point
code?

v.1.2.4 deliver maildir quota does not work

I'm using deliver for storing new mails (nfs).
Since v.1.2 deliver does not reject mails if over quota (maildir quota).

Peak Over Threshold values
Dear List
I hope you can help me: I?ve got a dataframe (df) within which I am looking
for Peak Over Threshold values as well as the length of the events. An event
starts when walevel equals 5.8 and it should end when walevel equals the
lower threshold value (5.35).
I tried ?clusters (?)? from ?evd package?, and varied r (see example) but it
did not work for all events (again

[LLVMdev] LLVM for heterogenous platforms
Hi llvm,
it's for sure an obvious idea to use llvm as IR for heterogenous
platforms (e.g. CPU+GPU).
In theory someone could write plain C/C++ code, which by clang is
translated to llvm-IL and then
together with JIT-backends packed in an appropriate executable. Thus all
the limitations
and hassles of openCL or CUDA could be avoided. I wonder if there
already is a related project?
