Allocating all memory up front
Hi guys,
I'm currently working on a CELT implementation for FMOD, and one of the
things we want to do is have all memory required allocated beforehand.
This is before we have any information about what sounds will be played.
We would like to create all of our CELTDecode instances up front.
Because celt_mode_create() requires a sample rate and number of channels
passed in, this

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

ASM runtime detection and optimizations
I wrote a proof of concept regarding the cpu capabilities runtime
detection and choice of optimized function. I follow design which had
been discussed on IRC.
Also, i notice a little drawback: we must propagate the arch index
through functions which don't have codec state as argument.
However, if it's look good, i will continue to implement it.
Best regards,

Cross Platform Audio Library
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi all,
I was wondering if anyone had any advice on an audio library that is
better suited to be paired with Celt in terms of latency. I'm working
on an application that I would like to have running on both
windows/Linux systems. I started by using the OpenAL library but I have
run into an issue when feeding OpenAL small mono sample sizes that

CELT/Opus Status Update
Hi everyone,
I've made several posts recently about CELT being "replaced" by the Opus
codec ( http://opus-codec.org/ ) and I thought it was time to give an
update on what's going on.
As many of you know, I've been involved at the IETF on this new Opus
codec, which essentially merge (a modified version of) Skype's SILK
codec with CELT. This is more than just two codecs

ARM NEON optimization -- celt_fir()
Hi all,
This is Linfeng Zhang from Google. I'll work on ARM NEON optimization in the
next few months.
I'm submitting 2 patches in the following couple of emails, which have the new
created celt_fir_neon().
I revised celt_fir_c() to not pass in argument "mem" in Patch 1. If there are
concerns to this change, please let me know.
Many thanks to your comments.

STATIC_MODES, fft and prob members
Hi Guys,
I've just been looking into STATIC_MODES. My plan is to generate and
store the modes as part of our sound banks when they are encoded.
I have noticed that even with STATIC_MODES turned on, celt_mode_create
still allocs and generates the fft and prob members (via
pitch_state_alloc and quant_prob_alloc respectively). I also notice that
in dump_modes.c, these two members are just

Some additions to CELT_RESET_STATE for 0.7.1
Hi Jean-Marc,
As the self-appointed keeper of CELT_RESET_STATE (since I may be the
only one actually using it) I've been kind of lax lately and have only
now tried to reconcile it with the state structures in the 0.7.1 drop. I
think (and feel free to contradict me here) that the following lines
should be added to CELT_RESET_STATE in celt_encoder_ctl:
st->fold_decision = 1;

[PATCH] Moved the application of the pitch gain to (un)quant_bands(). This doesn't change anything to the codec, but will make the next changes easier.

Ogg Drop?
Hi,
I asked this before, but it seems it hasn''t been updated. Who is responsible
for this and what are the problems?
The changes are in CVS (IIRC), but not in the current EXE available for
downloading.

[RFC PATCH v1] armv7(float): Optimize decode usecase using NE10 library
Optimize opus decode (float only) use case using ARM NE10.
Mainly effects opus_ifft and ctl_mdct_backward and related
functions.
Work based on previous Encode optimization using ARM NE10
library.
TBD: Add commit id of upstream Encode NE10 optimization patch
so that users have reference of how to enable this optimization

ogg vorbis on the pocket pc
Hi,
i'm not too familiar with how the ogg vorbis community works, so
i hope this is within the topic of the list, but i didnt really want to
leave this thing i've did out in the dark either. :)
i've just ported libvorbis, libogg, and vorbisfile stuff to the pocket pc
a while ago, it was pretty straight forward (just add a few more #ifdefs
around the ftoi function and some others) and

to meet me, just let me know.
