You're right! I forgot to say that I need only the encoder side (and
only for voice).

Using opus on ATMEL 32-bit RISC microcontroller
Hello Daniele
It would be worthwhile to attach an external serial flash or USB thumb
drive, if the intent is store data. This allows for far more flexibility in
storage

Well, the first question is whether you want encoding, decoding, or
both. If there's one you don't need then you can remove that

Using opus on ATMEL 32-bit RISC microcontroller
Hi all,
thanks a lot for your replies!
Sorry for my typo, the flash size is 8MB (Byte) :-)
Unfortunately I cannot use another flash because I'm working on a
proprietary board.
Jean-Marc, thanks for your suggestions.
I thought to use fixed point for convenience, but I can work on floating
point too, so I will take in account the codec2 (I didn't know it).
Moreover, if you all have

Then you can remove all of the decoder. As for the encoder, it depends
on the bitrate and sampling rate you want (more below).

Minimum files for building an embedded Opus library
Dear sirs,
I'm trying to build an Opus library for an embedded application to run on a
Microchip PIC32MX processor and I get a lot of errors in compilation time.
My question is, what should be the minimum files and options needed to have
such building, having in mind that only the very basic functionality in
fixed point arithmetic is needed?
Looking forward to your answer.

Fwd: HW requirements?
Hi all,
I would like to implement an opus encoder on a TI CC2650 MCU (128 kB Flash).
I did not find any information about the hardware requirements of opus, but
I found that someone already had trouble with the flash size with the 512
kB ATMEL AT32UC3B0512. (http://lists.xiph.org/pipermail/opus/2016-August/

[PATCH] Refactor silk_LPC_analysis_filter() & Optimize celt_fir_permit_overflow() for ARM NEON
Hi Jean-Marc,
The original celt_fir() is a little bit messy. It has 2 branches chosen by
#ifdef SMALL_FOOTPRINT.
For floating-point, the 2 branches are identical (except the operation
sequence of accumulating x[i] to sum, which is not a big deal).
For fixed-point, the 2 branches are different. I separate them into 2
functions: the new celt_fir(), and celt_fir_permit_overflow() which is the

So, one of the points of SMALL_FOOTPRINT is to reduce the code size on
targets where this matters (even if it means running slower), but this
is an awful lot of code.
I think it makes much more sense to expose the

patch to fix error in src/opus_multistream_encoder.c when DISABLE_FLOAT_API is defined
Hello,
for your consideration.
The following patch moves the channel_pos()
function from within the #if !defined(DISABLE_FLOAT_API).
This change is required when compiling with FIXED_POINT
and DISABLE_FLOAT_API defined.

[PATCH 02/22] drm/atmel-hlcdc: Use simple encoder
The atmel-hlcdc driver uses an empty implementation for its encoder.
Replace the code with the generic simple encoder.

Thanks Boris.
@Daniel, do you want me to resend this patch or will you fix it directly in mode-fixup git branch?

[PATCH 03/20] drm: atmel-hlcdc: Rely on the default ->best_encoder() behavior
We have a 1:1 relationship between connectors and encoders and the
driver is relying on the atomic helpers: we can drop the custom
->best_encoder() and let the core call drm_atomic_helper_best_encoder()
for us.

Speex for TI MSP430 microcontroller - estimating CPU speed requirements?
Interested in building a speex codec (basically audio <-> speex <-> data
stream) using TI's small MSP430 microcontroller. Is there any way to
estimate feasibility based on CPU requirements? Example - speex is happily
encoding on an old Pentium-1 processor (166 MHz) using about half the CPU
(as reported under Linux); the TI microcontrollers are much slower yet
(8-16-25 MHz) and

I can fix the typos, but I'm meh on the whitespace change ;-) Imo that
