similar to: OPUS on the ARM-linux platform

Hello, I am interested in porting OPUS to an embedded platform. The idea is that the encoder and decoder will run on different processors. In order to choose the proper platform, I need an estimate of the resources which are needed for OPUS. I read the following in the OPUS wiki: "The Opus code base is written in C89 and should run on the vast majority of recent (and not so recent) CPUs.

Respected Sir/Madam, I am working as Research Scholar at IIT, Bhubaneshwar, which is one of the pioneer educational organization in India. ( http://www.iitbbs.ac.in ) My assigned task is to transfer voice signal (Audio in future) over wireless sensor network. I have Arduino DUE, Arduino Mega, TMS320C6713 DSP board, TMS320F28379D Lunch pad, FPGA boards and necessary Microphone, filter, amplifier,

Hi, I am trying to compile the opus-1.0.2 source code for ios. When I import the files in Xcode and try to build, the build fails. How can we successfully compile opus using Xcode? Are there any special configurations? Thanks a lot in advance! -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I’m currently using the Opus encoder in an embedded device with a small ARM Cortex M4, compressing audio in real time and it works great. My implementation is similar to the application note from Texas instrument “Implementing OPUS Voice Code for TM4C129x Device”. The next step in my application is to add voice activation capability in real-time while compression is in progress. Reading

Hi Dan, I suggest you try the code in git master, which has further ARM optimizations compared to 1.1.

Hi Ralph, I have pushed patches to enable radix 3 and radix 5.

Hi, Just to clear things up... So 1.1 has some new analysis code that increases the amount of CPU. When building as floating point (which you appear to be doing, right?), the new code is enabled at complexity 7 and up (opusenc defaults to complexity 10 IIRC). This is why you've been seeing an increase in the CPU time. In version 1.0.x, complexity 5-10 are the exactly the same for music.

The patch prevents KEIL MDK compile warnings, like:   warning:  #1035-d: single-precision operand implicitly converted to double-precision Actually ARM Cortex-M4F has only a *single precision* (float) FPU. It's suit for all platforms. See the comment at the begin of patch file. Sincerely Forrest Zhang -------------- next part -------------- Specify the floating point constant with single

hi folks apologies for sending a commercial mail. I am the CEO of http://talk.to - a unified messaging product. We are still in early stages of launch. We intend to build in voip capabilities in our product. Our product is intended to work in browsers and on all mobile platforms. We are looking for someone who can provide us an ARM-Neon optimized version of Opus for use on mobile platforms so

Hi, I'm planning to use Opus codec on a ARM cortex M7 device running at 400MHz. Con you please suggest the best configuration directives that I have to set in the config.h file in order to obtain the best perfromances on the cortex M7 architecture? Actually I have compiled libopus 1.2.1 with the following cnfiguration parameters: #define VAR_ARRAYS  1 #define FIXED_POINT  1 #define

Hi everyone, I have lately been evaluating the performance of various audio decoders, particularly for ARM devices (Cortex A8 / A9). The context is audio playback in a game engine, and thus decoding performance is of particular interest. Looking at Opus versus Vorbis on a Cortex A9 smartphone, the numbers look approximately like this: Vorbis (tremolo decoder) 9.3 Mb PCM/s Opus (libopus 1.1)

Hi everyone, I am working on Ne10 project. Ne10 provides NEON optimized FFT routines that are much faster (compared to those without NEON), on most ARMv7-A and all ARMv8-A devices. How about integrate it into Opus? I am not familiar with configure script, but I find "Optinal Packages" in it. If we provides --with-ne10-fft option, the one extra thing that users need to do is to

Hi,I have a question about implementing opus codec and I appreciate you to answer it.I want to implement this codec on LPC1768 which has ARM cortex m3 and in keil uvision4, I don't know which file of opus library should be added to the project environment.Best regardsHamed KarbasiSharif University of Technology -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Thank you for your response. I pulled yesterday to commit da97db1ca1f92592af3534c9a2596da0e9a009ca, added a bunch of more defines to my compile options, and assembled & linked in armopts.s,celt_pitch_xcorr_arm.s. Performance jumped up from about 4.8 Mb/s to 5.3 Mb/s on the same device, so it is improvement. Not sure what other tweaks there would be to try, but if it could match the

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 .

I?m trying to build Opus (git master) for iOS, and it doesn?t build unless I disable the ARM assembly. It looks like the problem is that Apple?s assembler doesn?t support all the assembler directives that the GNU assembler does. I suspect this is a combination of the fact that Apple platforms are Mach-O rather than Elf, and just the fact that Apple?s assembler is extremely divergent from the
