FIXED_POINT
Hi,
I've recently successful built and run CELT under Windows using
"testcelt.c" example file. Since I'm about to port it on a embedded
platform i activated the FIXED_POINT #define.
I included fixed_generic.h and without other changes to the code i tried
to encode and decode the same file i previously used.
The output though is completely saturated i.e. it jumps from -32768 to

CELT decoder complexity
Hi,
We're using Celt 0.7.1 at the moment. We're thinking to update the code to
a newer version of it. Is there an appreciable complexity (decoding time)
difference among versions (0.7.1 - 0.8.1 - 0.9.1 - 0.10 - 0.11.1)?
If so, which one is the fastest?
Thanks

MAX_PERIOD
Hi,
In order to fit the decoder in memory in our embedded architecture we set
the MAX_PERIOD #define equal to the frame size. This doesn't affect the
code bit accuracy in normal decoding. The #define it's used
celt_decode_lost function though. Is it possible to get celt_decode_lost
to work with a value different from the default?
Thanks

Celt_decode_lost function (File: P0773)
Hi,
I'm using Celt version 0.7.1 in low complexity mode (i.e. no pitch
information). In case a packet is lost i was planning to use the
celt_decode_lost function. I realised though it uses pitch information
inside.
Does the celt_decode_lost function still works with no pitch information?
Are there some changes to be done?
Thanks

CELT complexity question
Hi,
I'm testing CELT 0.7.1 speed performance and I'm focusing now on the
complexity switch. I've dug in the archive and i found some information.
Is it still true that there are two ranges?
- 0-2 low complexity mode
- 3-10 high complexity mode
If no input is given is 2 hence low complexity mode the default setting?
Does the complexity mode affect decoding as well?
Thank you

Bitrev for FFT
Hi,
Our DSP has a built-in bitrev instruction so we're exploring the
possibility of calculating the bitrev every time instead of filling the
table during initialisation, hence saving some memory.
Our frame size is fixed to 320 samples. The two FFTs sizes for normal
block and short block are 160 and 40 respectively. It's not really clear
how the function

Celt 0.7.1 High complexity VS Low complexity
Hi,
I was checking complexity modes of CELT 07.1 encoder. If i got it
correctly everything is driven by pitch_available variable set in
celt_encoder_create function. By default it's set to 1 hence high
complexity mode is used all the time. I tried to disable it and although i
couldn't hear any particular difference in the decoded audio quality, the
cycle count of the encoder dropped

BYTES_PER_CHAR
Hello,
I'm porting CELT 0.7.1 to an embedded platform and unfortunately (at least
for me) CHAR is defined as 16 bits. I now got the vocoder compiling but
when i compare the encoded output with a windows build, they don't match.
Among the other problems i think that the char definition is one of the
biggest players. I've seen in arch.h the following definitions:

Error resilience
Hi,
We're testing CELT (version 0.7.1) error resilience capability. We've used
already celtdec packet-loss options. Hence we know what to expect in case
of whole packet loss.
How does Celt respond to a broken encoded packet? Is it always better to
discard it and decode the missing frame through decode_lost?
We have the hardware capability of protecting the frame with multiple
CRCs.

Celt 0.7.1 Fixed math
Hi,
I'm using Celt 0.7.1 in fixed math mode. In the celt_encode function, if
the variable has_pitch is true, the function pitch_search is called.
Within this function the find_best_pitch subfunction is called.
Here the variable "float score;" is defined.
Is this right? I was expecting not to see any float declaration in the
fixed math code. Is it possible to redefine it as

Possible Bug
Hi,
Fiddling with Celt i found a possible bug. I'm using CELT 0.7.1, frame
size 256, sample rate 32k and bitrate 64k.
Here is the scenario: decoding side, celt_decode function.
The "dec" structure is created at each function call and it's initialized
with ec_dec_init function. The attribute "end_byte" is not initialized
though. Decoding a file the behaviour is the

Stereo <-> Mono
Hi,
Does Celt (in particular version 0.7.1) exploits correlation between the
two channels in stereo mode?
In practice, is it possible to use the two channels as two mono signals
without affecting quality?
Thanks

uint decode error on visual studio...
Is this a common warning? The decoder doesn't return an error on it, but I
see it a lot in my test application on windows. It is non existent on my
linux box. I haven't tried mingw yet.
please note that I'm using visual studio 2008 w/the vcproj that Bjoern
Rasmussen made for 0.5.2 (w/some file references removed) at the moment and
it is giving a lot of C4554 warnings

A (minor) bug and a request
Cheers all.
I believe that the first line in the function FLOAT2INT16 in celt.c
which is now:
x = x*32768.;
should be:
x = SCALEIN(x);
This only makes a difference if you change the SCALEIN and SCALEOUT
macros (which I do).
The new feature I would like to request is the addition of a
CELT_RESET_STATE control for both the encoder and decoder. I cache
encoder and decoder instances and
