Hi: currently, I am doing opus optimizing work on cortex-M4F(MT2523D), but it has little improvement, hope anyone can sync the work with me .

Hello Opus, I?d like to report a bug in the fixed point OPUS code: line 336 (or thereabouts), operand FIND_LPC_COND_FAC should be replaced with SILK_FIX_CONST(FIND_LPC_COND_FAC ,32), otherwise multiplication by zero typically occurs. please confirm.

Actually opus-tools-0.2 has the same issue. Sincerely Forrest Zhang -------------- next part -------------- Add "#define FIXED_POINT 1" into the top of resample.c, outputs of resample are all zeros. Actually the data transform is required before/after calling speex_resampler_process_native(). diff -Naupr libopusenc-0.2.1-vanilla/src/resample.c libopusenc-0.2.1/src/resample.c ---

Does a comprehensive set of instructions on how to compile Libvirt on a Microsoft Vista platform exist? Has this ever been accomplished? I would very much appreciate input from persons who can give me confidence that a Windows client application can be developed on top of Libviet that connects to a QEMU system on an Ubuntu server. The Libvirt Windows Support page

Hi, I would like to use OPUS codec to compress and decompress an audio stream for full-duplex intercom application; I would like to use a microcontroller equipped with Cortex-M4 core without NEON running at 72MHz. Does the OPUS codec works fine on that architecture? Do you have some benchmark data? Thank you in advance. Best regards. Daniele -------------- next part -------------- An HTML

Today I updated to trunk the toolchain for my work developing on Cortex-M4F. I was super excited to see three commits by Tim Northover that actually attempt to improve the machine code generation for my target, or any ARM target for that matter (as opposed to other important work on compiler correctness or architectural elegance or formatting comment white-space, I mean). Is he alone or are

Hi all ! I just learned about the Opus codec and would like to try it out on my NRF52 (Cortex-M4) target.   I've been struggling a bit with the "trival_example.c" setup but repeatedly run into "hard fault" crashes when stepping through the code. Firstly; for a "bare bone" configuration, does the following compiler directives make sense ? UDEFS =

I rebased my previous 3 patches to the current master with minor changes. Patches 1 to 3 replace all my previous submitted patches. Patches 4 and 5 are new. Thanks, Linfeng Zhang
