Opus for audiobooks etc
I know the focus for Opus is low delay, but I've been watching its
development with interest because of the potential for audiobook/podcast
use, where latency is practically irrelevant. I hear the upcoming USAC
codec will give good results for this niche (though listening test
results don't seem to be available to the public yet), but I also hear
it'll be extremely patent

High Frequency Hiss with Opus at 48 kbit/s
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi to everybody.
First of all I hope this is the right place to discuss such an
(nitpicky) issue.
I've just been testing the current Opus release and for mere curiosity
compared its performance to WMAPro with CD quality music at low
bitrates (48 kbit/s).
While Opus generally does a very good job, I found one particular

Patches for adding 120 ms encoding
Hi Felicia,
A few comments:
> - /* CELT can only support up to 20 ms */
> subframe_size = st->Fs/50;
> - nb_subframes = frame_size > st->Fs/25 ? 3 : 2;
> + nb_subframes = frame_size/subframe_size;
This will use six 20ms frames to make a 120ms packet, even for
SILK-only mode where frames can be up to 60ms. For SILK, two 60ms
frames would be a more

Patches for adding 120 ms encoding
Attached is the amended second patch. It now extends the multistream API as
well to 80/100/120 ms and incorporates changes based on Mark's comments.
Thanks,

CELT 0.3.2, listening tests
Hello all,
This is slightly off-topic, but should be of interest to some people on
this list. I just released version 0.3.2 of the CELT ultra low-delay
audio codec (http://www.celt-codec.org/). CELT is designed to encode
high quality speech and music with less than 10 ms delay and at rates
starting from around 32 kbit/s.
This version is "special" in that it is the basis for some

[EXTERNAL] Re: Developing OPUS on TI CC3220
Thanks Jean-Marc,
I was able to get both encode and decode working the CC3220 device! But for bi-directional communication, I need decode and encode to occur in less time than the frame size I’m sending (20 ms).
Currently decode takes 16~22 ms and encode is ~13 ms. What is the best way to try to reduce this time? Also, unsure why encode is taking less time than decode...
I've also

Patches for adding 120 ms encoding
Hi Ulrich, thanks for the suggestion. My concern is that one of the valid
inputs is "2.5", which would require conversion to an int, e.g. x10, but
doing something like this would start to affect the code readability.

PLC Question & OPUS Migration?
Hello everyone, I have been having trouble utilizing the PLC function (I
think). In older versions (0.7.1) a pointer to NULL did the trick, but with
code from the tip of the GIT repository, this method causes the codec to
crash on the C55x fixed point platform. I have not determined where the
crash occurs.
I have also attempted to pass in an array of zero's and this creates an

[RFC PATCH v1 0/4] Enable aarch64 intrinsics/Ne10
Hi All,
Since I continue to base my work on top of Jonathan's patch,
and my previous Ne10 fft/ifft/mdct_forward/backward patches,
I thought it would be better to just post all new patches
as a patch series. Please let me know if anyone disagrees
with this approach.

[RFC PATCH v1 0/5] aarch64: celt_pitch_xcorr: Fixed point series
Hi Timothy,
As I mentioned earlier [1], I now fixed compile issues
with fixed point and resubmitting the patch.
I also have new patch that does intrinsics optimizations
for celt_pitch_xcorr targetting aarch64.

For reference, you can use the Ne10 pre-built libraries

stack + heap sizes
??
hi ?Jean-Marc,
?
thanks for your answer.
But still I am struggling to find a reasonable upper limit for the RAM sizes.
?
You say we need 4.5/9.0 kB for enc/dec per channel.
But are those sizes really independent of any settings, like frame_size,
bitrate, complexity, etc. ?
?
at least in our configuration I find these requirements:?

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

memory violation in mode_create() !
?
There seems to be a memory violation when calling celt_mode_create(48000, 240).
?
The function compute_pulse_cache() calls celt_alloc (the second one,
bits=celt_alloc()) in order to allocate 343 byte, but it is using about 872
bytes at that location, which will be deleted by the following allocations.
?
In this case the following encoder call crashes at first run.
