Alleged bug in Silk codec
Hi Jean Marc,
please find attached the audio file (mono 16khz). I shortened it to about
10 seconds. I also add 2 patches that worked for me. Further info that
might help:
- The problem seems to be related to silk_burg_modified not reaching the
maximum gain, so the actual filter order is 16 rather than 2 (which is
what would be expected with a sine wave).
- The problem seems to happen when

Hi all !
If someone could give me a hint on how to proceed with the following i'd be
very happy:
I have a test setup on an nrf52832 (Cortex M4) in which I receive audio
from a PDM microphone (64 sample frame) and pass it directly to an I2S
device i.e. from ISR to ISR. With uncompressed audio this works just fine.
Now I try to insert OPUS1.3 in the path but cannot make it work. The

Suggestions and questions
Hi!
I'm not a developer but it takes one to answer my questions. I was just
thinking about how the command line encoder could work in the end (after
having played with encoder_example)
Some ideas:
1. There could be the option of having a -q switch (just like oggenc)
controlling BOTH audio and video so that for each level of q the sum of
video and audio bitrates could be known (sort of

Alleged bug in Silk codec
Hi Jean-Marc,
well spotted! The patch provided fixes the issue for me.
Nevertheless, in my code (and I would suggest doing the same in libopus) I
am going to replace the function with one that accumulates on 64 bits and
then calculates the shift, for at least 4 reasons:
- It is less and simpler code
- The result is likely to be slightly more accurate in case big numbers

Alleged bug in Silk codec
Hi Marcello,
Thanks for the info and the proposed fixes. I'm currently investigating
what's going on here before deciding on the best way to fix the problem.
Have you been able to figure out why it doesn't work for rshifts >= 3?
Cheers,

Alleged bug in Silk codec
Hi Marcello,
It turns out that the problem has a much simpler explanation. As far as
I can tell, it's actually a bug in silk_sum_sqr_shift() and this trivial
patch appears to fix the problem:
http://jmvalin.ca/misc_stuff/sum_sqr_shift_fix.patch
It would still require some testing to check that the fix doesn't have
any bad side effect. Let me know how well the fix works for you. Again,

Alleged bug in Silk codec
Hi Marcello,
Actually, we were careful to avoid the undefined behaviour here. In
fact, we are specifically running a clang test detecting undefined
behaviour. If you look at the silk_SMLABB_ovflw() macro, you will see it
is based on silk_ADD32_ovflw(), which is defined as:
#define silk_ADD32_ovflw(a, b) ((opus_int32)((opus_uint32)(a) +
(opus_uint32)(b)))
By casting to unsigned, all the cases

Alleged bug in Silk codec
Hi,
Apologies if this is a known issues, but I have found what I believe is a bug in the fixed point implementation of the Silk codec and could not find any mention on this in the archives.
The bug can be easily reproduced with the fixed point demo program (./configure ?enable-fixed-point ?disable-float-api && make) using the following command:
./opus_demo voip 16000 1 23000

Right, there shouldn't be a problem with undefined behavior.
That said, a 64 bit implementation will work very well - in fact that's how
it was done originally.
The reason for the current implementation is to minimize 64-bit operations
in order to improve performance on limited-width architectures. This
functions gets used extensively, and I think the current implementation is
faster on
