mdct explanation

Suppose we want to calculate a MDCT (encode side):
(x_ is input (time) samples, w_ is window, b_ is output (freq) samples):
b_k = \sum_{j=0}^{4N-1} x_j w_j \cos{(2k+1)(2j+1-2N) \over 8N} \pi
After setting
a_j := w_{-j-1+N} x{-j-1+N} + w_{j+N} x{j+N}, j < N
a_j := w_{j-1-N} x{j-1-N} - w_{j+3N} x{j+3N}, otherwise
(or something similar; the cos'es should agree)
we get
b_k = \sum_{j=0}^{2N-1} a_j \cos{(2k+1)(2j+1) \over 8N} \pi
This is a DCT-IV.

We do this when determine the (n+1)^2 + 2j listed above, but we can
validate that here as well.
5) For opus_multistream_surround_encoder_init(), the same comments as
for opus_multistream_surround_encoder_get_size() maybe some code can be

[Patch] Non-diegetic support for channel mapping 254
Hello all,
Attached is a proposed patch for Opus that allows support for encoding
non-diegetic stereo audio as a coupled stream for use with channel mapping
254. It also rejects channel counts that are not (n+1)^2 + 2j, where n is 0
to 14 and j is either 0 or 1 (See IETF public draft doc attached for
clarification).
Please let me know any suggestions / concerns / comments.
Thank you for your time,
Cheers,

Describing this virtual accesses by using some kind of intrinsics

Like this you can simply transform your linked list into virtual

mdct question
Hi,
Can someone tell me which MDCT and invMDCT equation uses? I implemented the
invMDCT one given in
eusipco.corrected.ps file (handed out by Monty way back) and it produces
different time domain samples.
I tried both the FFT method and the slow way directly from the equation and
couldn't reproduce the results
from the original code. This leads me to believe that the forward

Again some questions about multilevelanalysis
...(G), and an explanatory variable at the second level (z[1])
If I am correct, this leads to the following model (I will write indices in
squared brackets and gamma as gm):
y = gamma[00] + gm[10]x[1ij] + gm[20] x[2ij] + gm[01]z[1j]+ gm[11]z[1j]x[1ij]
+ gm[21]z[1j]x[2ij] + U[0j] + U[1j]x[1ij] + U[2j]x[2ij] + R[ij]
Now I start modelling step by step and I would appreciate any corrections if I
got something wrong.

With one explanatory variable:

[LLVMdev] speculative parallelization in LLVM
Hi Tobi,
Thank you for your reply :).
I know that array accesses are handled as pointers in LLVM, but as I understood
Polly is focused on statically analysable code. As you mentioned: proving that
pointer accesses actually represent virtual array accesses.
In the case of a linked list for example, parsed with a pointer p = p->next, I
expect that Polly will not handle this code. So I
