Min and max cutoff frequency
Dear list,
Could you please tell me the values of the minimum and maximum cutoff frequencies for each coding version of the 44.1 kHz sampled data? For instance, are the values fmin=100 Hz and fmax=12 kHz valid?
Thank you very much in advance.
Kind regards,
?

Questions: FLAC performance, compression ratio and extra documentation
Dear list,
I' m studying FLAC performance, and I'd like to know how much
compression can be achieved for different audio files.
1) It seems that
for nontonal sound (wideband noise), the compression factor is better
than for compound sound (tones + nontonal components),
which is typically 2. The reason for this result could be the following: the
LPC filter is more suitable for

Maybe Monty will make a video about it one day and we will all understand

Request: temporal windows
Dear list,
I am looking for different window functions used in perceptual audio coding. In the mp3 format, these windows overlap with each other, but I haven't found any information about their mathematical expression, nor their numerical values (see attached document). Which temporal windows are used in ogg audio coding?
Thank you very much in advance.
Kind regards,

Question about residue and pdf
Dear list,
I wonder if the flac encoded file has a great amount of bits due to the residue. I mean, what percentage of the flac file has information of the residue? Is this sequence represented by more than 80% of the flac file?
On the other hand, which is the value
typically adopted for the parameter "n" in the Rice coder?
I know these results depend on the input wav file, but I

Is FLAC hardware independent?
Dear list,
We are investigating about some state-of-the-art
lossless audio codecs and their performance in terms of? rate and
compression ratio. Therefore, it is very important to us to know whether a
codec is hardware independent, i.e. if it produces the same output file
regardless of the hardware. Could you please tell me whether FLAC is
hardware independent?
Thank you very much in advance.

Using line spectral pairs for LPC quantization
Dear Stefan,
In the paper "Improved Forward-Adaptive Prediction for MPEG-4 Audio Lossless Coding", a non-linear compander is applied to the parcor coefficients prior to quantization. This compander is designed in order to minimize quantization error, especially for magnitudes close to unity.
If you determine the typical distribution of magnitudes of the LPC coefficients, you could

Min and max cutoff frequency
Presuming that you are asking regarding the Ogg Vorbis audio format, the
correct answer is: there is no minimum or maximum cutoff frequency. Vorbis
can code all frequencies from DC to Nyquist. What Vorbis will actually do
is extremely complex, extremely nonlinear, and highly dependent on
bitrate. If you are in the mentality of linear time-invariant filters, you
will never be able to understand

Dear list,
Following Victor Westmann's idea, I'd like to translate FLAC's site to Spanish. I'd be very grateful if anyone offers to give me a hand in this.

FLAC suddenly compresses more - why?
Hi guys,
I use EAC to save and compress my CD's to my network drive. In the past my
compression to Flac was slightly worse than the file size shown by EAC. Now,
since about two weeks ago, my compression ends up at about half the size of EAC
i.e. I went from a compression ratio of approx 70% to a ratio of 30%. I get the
feeling that the compression is somehow missing something. Or is the

Win10 cannot access linux shares
Hi,
When I upgraded from Fedora 22 to Fedora 25 my Win10 box lost the
ability to connect to shares on the F25 box. The F25 box can still
access shares on the Win10 box.
F25 is currently running Samba 4.5.13 and I have a simple workgroup
setup. Let's call the Win10 box 'fred' and the F25 box 'ethel'.
When fred tries to access a share on ethel, I am prompted for username

CentOS for musicians?
Hello,
still searching but didn't find very precise answers yet, is there a
computer-aided musical creation -oriented flavor of CentOS (like the
Ubuntu Studio)? Or would it be about gathering stuff from different
repos and setting up everything by hand?
A repository that would provide low-latency kernel (realtime one?):
I've found the CentOS-RT from the CERN + (1)).

[LLVMdev] Measure execution time of each basic block
Jon,
I need to create a database of basics blocks and their execution time. The
only thing I'm concerned is if a block A is more expensive than a block B.
Do you think that even with the overhead I would be able to get the A > B
information?
Like: overhead + time(A) > overhead + time(B) => A > B.
If so, I'm not too much concerned about the accuracy.
Not sure if I was clear,

Port to SCO Openserver with PAM enabled
Hi all, I'm writing to you becuase I have compiled PAM in SCO (now Caldera)
Openserver 5.0.x, and when I tried to use SSH with PAM enabled, y realized
that OpenSSH depends on the user to exist en the /etc/passwd, and
/etc/shadow databases, or equivalent ones (it uses getpw...() functions to
determine validity of the user).
In Linux, the simlpe solution is to use nsswitch, but it seems to hard
