similar to: [PATCH] Fix const struct to work with C++ compilation

Hi, We are rebasing our audio compression subsystem using OPUS rather than SPEEX. The platform is Android but this piece is written in C code: we need to support armv5/armv7/x86 architectures.... and we use the released opus-1.1beta package from here<http://downloads.xiph.org/releases/opus/opus-1.1-beta.tar.gz>. A lot of our OPUS build system + code to drive the audio compression has been

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

Optimize opus encode (float only) usecase using ARM NE10 library. Mainly effects opus_fft and ctl_mdct_forward and related functions. This optimization can be used for ARM CPUs that have NEON VFP unit. This patch only enables optimizations for ARMv7. Official ARM NE10 library page available at http://projectne10.github.io/Ne10/ To enable this optimization, use --enable-intrinsics

I am in the process of adding speex 1.2rc1 to a project of mine, not via compiling as a static library yet including the source and compiling with my own to create a dynamic link library. This worked fine with the last beta release yet is causing problems with this release candidate. The problem is in the file scal.c which is about M_PI being undefined, this file was added to speex in said

As some of you know, I'm creating a hardware MDCT core. At the moment I'm working out the best way to create a lookup table for the trig values, as set up in mdct_init: /* trig lookups... */ for(i=0;i<n/4;i++){ T[i*2]=FLOAT_CONV(cos((M_PI/n)*(4*i))); T[i*2+1]=FLOAT_CONV(-sin((M_PI/n)*(4*i))); T[n2+i*2]=FLOAT_CONV(cos((M_PI/(2*n))*(2*i+1)));

Hi, I am looking into fixed-point code of the CELT decoder for real-time application. Here are some questions..

This array is being initialized differently for the decoder, depending on frame size and sampling freq. of the bitstream .. Could you provide us with fixed-point code for initialization of

Oops, I was a bit sloppy in my organization, and also sloppy on a few facts. I did not intend to imply that A-52 was lossless - I was merely using it as an example of an open specification format that cannot be implemented and sold without being licensed. I'm glad that we are finally getting lossless formats accepted in large public standards. The liba52 library may not be legal. I

Hi all! What is the right way to report bugs in libopus? I couldn't find any publicly available bugtracker. Anyway, the problem I need to report is that some source files in libopus are missing copyright headers. This breaks license check script that we use in chromium to validate licenses for third-party dependencies. Specifically the following files don't have copyright header:

Hi, I am trying to build a VERY basic neural network as a practice before hopefully increasing my scope. To do so, I have been using package "neural" and the MLP related functions (mlp and mlptrain) within that package. So far, I have created a basic network, but I have been unable to change the default activation function. If someone has a suggestion, please advise. The goal of the

First off, I'm not an expert in this field, but I thought I could probably answer a few of your questions. If anyone else wants to give a more complete explanation, please do.
