Hi all, for numerous reasons I am now trying to build Opus with Windows / Visual C++ Express. So far I have been using Linux/OSX/MinGW only. The normal Opus build works out fine but I wonder how I can enable the Opus-custom-mode with Visual C++ Express. Can anyone help ? Thanks in advance, best Alex -------------- next part -------------- An HTML attachment was scrubbed... URL:

Given the tests that had to be disabled for NE10, I suspect we will not really be able to use it for CUSTOM_MODES, which should be the only time nfft is a power of 2. So I'd suggest just disabling the support when CUSTOM_MODES is enabled and putting in an assert. >> It would not be too ugly if we put them together somewhere and document them well enough.

I think I was too quick: Today I compiled the whole project and I get these unresolved symbols: error LNK2001: Nicht aufgel?stes externes Symbol "_opus_custom...

Hi,I have been trying some different sample rate and bitrate combinations to get a feel for how CELT behaves,too, like Andrew Lentvorski. But I want to use VBR option.I want to ask a question about VBR in CELT codec.Can we use VBR option in CELT ??? "byte_per_packet" variable in code means constant bit rate, does not it ?In this code : bytes_per_packet is constant.len =

Hi all, I'm sending patch "Optimize silk_warped_autocorrelation_FIX() for ARM NEON" in an separate email. It is based on Tim’s aarch64v8 branch https://git.xiph.org/?p=users/tterribe/opus.git;a=shortlog;h=refs/heads/aarch64v8 Thanks for your comments. Linfeng

Right that I had completely missed, I have added the files and verified that it builds with CMake from the tar on Linux (out of the git repo) I am parsing the package_version file from the tarball if it exists so it should maintain the version info. //Marcus ________________________________ From: Jean-Marc Valin <jmvalin at jmvalin.ca> Sent: Tuesday, April 2, 2019 11:38 To: Marcus

Hi all, I have already added support for scaled forward non-power-of-2 floating-point FFT: https://github.com/projectNe10/Ne10/commit/79c3d787302f8d74b9bcfe6545d487cdf1b101d9 Two flags are added to cfg structure: is_forward_scaled and is_backward_scaled. By setting is_forward_scaled to anything but zero, ne10_fft_c2c_1d_float32_neon will scale the output. So we can remove need for one buffer on

...des. I don't completely understand what is going on in the following code. Could you provide some guidance on what parameters are now acceptable? I am trying to create a stereo channel with Fs=48000 and 128 byte frames, but get NULL returned from the celt_mode_create function. I am not defining CUSTOM_MODES_ONLY (because I don't know what it means). On the last couple of lines of code, there is no error (error=0), but it appears that you always return NULL..?

Normally, it should just be a matter of adding #define CUSTOM_MODES to the Windows config.h file. Cheers, Jean-Marc

Hi Felicia, I've not yet really looked into the details, but first here's a few comments and questions: 1) Why does the patch need to define SKIP_CONFIG_H and CUSTOM_MODES at the beginning? I can't see a reason for that. 2) The whole code is inside an #ifdef FIXED_POINT. It seems like it the file shouldn't be compiled at all for float, so that #ifdef would be unnecessary. Or did I miss something? 3) The code as it is written is pretty hard to follow. Can yo...
