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

Please redirect me to another appropriate list if such a list exists. I have the very common problem of identifying which (subset of) variables are

Hi Everyone, I just merged a lot of changes in the CELT master branch. This should solve the following issues: - tonal artefacts (birdies) at low bit-rate - tonal artefacts in stereo at all rates - low-frequency noise (roughness) on low bit-rate speech The code has been simplified a lot, but there's lots of changes, so please give this a try and see if anything got broken. Cheers,

Hi -- I'm looking at adding Speex decoder and encoder support to the Miles Sound System, a commercial library used by game developers on various platforms including PCs, the Mac, and game consoles. As part of my initial evaluation, I've gone ahead and downloaded the 1.0.4 and 1.1.1 Win32 binary distributions and played around encoding and decoding various files with the speexenc.exe and

Hi, I am new in asterisk and i've bought a X100p and a TDM400... First of all, how can i verify my config files ? Secondly, when i'm trying to pass a call to the outside, i ve a Notice about appdial.c (l 554) telling me: unable to create channel of type Zap ...and i don't understand... Finally, when i plug my analog phones in RJ45 of my TDM400, there is no tonality ( i'm not

Hi everyone, I'm pleased to announce version 0.6.0 of CELT, with many quality improvements. This includes better stereo coupling, better handling of transients, and better handling of highly tonal signals. In addition, packet loss robustness has been improved through the optional use of independent (intra) frames. CELT now supports a larger dynamic range, suitable for encoding 24-bit audio

Hello everyone, I was curious if anyone has performed any listening tests or done work with solo instrument performances with the CELT codec? I experience quite a bit of noise coming up with a heavily tonal stimulus, the worst offender being a trumpet. I understand some of this behavior is to be expected, this is a perceptual codec afterall, but was curious if anyone was able to find an elegant

Hello all, Please try this "patch". It changes the way the noise floor is used for quantization in a not-so-subtle way. At the very end of _vp_compute_mask, add the lines: for(i=0;i<n;i++) flr[i]=.01f*sqrt(flr[i]); The .01 is there to ensure the current codebooks will work. We will really need different, newly-trained codebooks with this change; then the

Hello people, Looks like Santa Claus thinks I've been a good boy this year. Here's the third in my performance patch series: d.m.l Apply after applying d.o.n and d.n.m; I don't know how much of those got applied to the CVS tree. What's inside: Request for help! Look in os.h if you're using a compiler or processor I don't use (I use gcc on K5, K7, G3). New MDCT! Now we

Dear list, I' m studying FLAC performance, and I'd like to know how much compression can be achieved for different audio files. 1) It seems that for nontonal sound (wideband noise), the compression factor is better than for compound sound (tones + nontonal components), which is typically 2. The reason for this result could be the following: the LPC filter is more suitable for

Hi everyone. I did a rough recording of an instrumental (electric piano sound) & e-mailed it to a friend in Vorbis 11025 Hz / mono. I was seeking a bitrate in the range 8-16k/sec. The song is 2:55 in length. q=-1 happily achieved a 12.6k/sec bitrate. All file sizes I mention in this are for files without informational tags. And I hope this isn't interpreted as trying to plug my music or

I've made a block diagram of the encoder because I tried to find out, how it works http://stoffke.freeshell.65535.net/ogg/block.html Although there are specifiation docs, that give very detailed information about single aspects of the encoding (or decoding) , I'm missing documenations that give a more general overview, about how the encoder works. (Vorbis Illuminated seems a bit

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.

Changes from RFC PATCH v3 - Just rebased on tip - For all else, please see notes from RFC PATCH v3 at http://lists.xiph.org/pipermail/opus/2015-March/002902.html - latest wip opus tree/branch https://git.linaro.org/people/viswanath.puttagunta/Ne10.git branch: rfcv4_final_fft_ne10 Viswanath Puttagunta (1): armv7(float): Optimize encode usecase using NE10 library Makefile.am

Changes from RFC PATCH v1: - passing arch parameter explicitly - reduced stack usage by ~3.5K by using scaled NE10 fft version - moved all optimization array functions to arm_celt_map.c - Other cleanups pointed out by Timothy Phil, As you mentioned earlier, could you please address all compile and linker errors/warnings coming out of Ne10 library? You can find my working Ne10 repo at [1] You

Changes from RFC PATCH v2 - fixed compile issue when just compiling for --enable-intrinsics for ARMv7 without NE10 - Notes for NE10: - All compile/link warnings are now in upstream NE10 - Only patch pending upstream in NE10 is the one that needs to add -funsafe-math-optimizations for ARMv7 targets. - Phil Wang @ ARM is working on getting this fixed. - Note that even without

Try using WavPack, http://www.wavpack.com/ This can losslessly compress 32-bit floating point WAVE-EX files, and faithfully preserves every chunk (which FLAC does not do). It is also free.
