Hi all I have spent the last three days evaluating CELT on our supported platforms. I found a bug in quant_bands.c, that due to processor/compilation differences did not cause an issue on x86 platforms, but is a problem on the MIPS processor embedded devices. When decoding on the MIPS devices, there was a lot of noise added during the decoding, the noise is mainly in the 15 khz to 21 khz range. The amount of...

Gents, In Version 8.1, QCONST16 is defined as follows in arch.h within the FLOATING_POINT section: #define QCONST16(x,bits) (x) However, in both celt.c and quant_bands.c, QCONST16 is referenced without a conditional FLOATING_POINT define. So when I compile as FIXED_POINT I get an "undefined identifier" for QCONST16. Am I doing something wrong? Thx, MikeH -------------- next part -------------- An HTML attachment was scrubbed...

Tim, et al, I have run into several problems with V0.8.0. I will address them seperately. 1. My compiler is complaining about the following code in celt.c which seems to define metric first as celt_word32, then as celt_word16. Am I mis-interpreting something? ?? VARDECL(celt_word32, metric); ?? ALLOC(metric, len, celt_word16); Thx MikeH -------------- next part -------------- An HTML attachment

Hi everyone, I have profiled Opus on AArch64. I just run opus_demo with some pcm files. Following is time proportion of FFT with different bitrate. Bitrate | Time cost by FFT/iFFT 24kb/s | 15% 48kb/s | 15% 96kb/s | 13% Any comment? I want some data close to real application, any suggestion?

Hey everyone. I've been designing my own audio codec with extremely strict decode-performance constraints (including a fixed block size), which led me to attempting a number of unorthodox things to squeeze as much quality as possible. One surprising thing I discovered just earlier today was an extremely cheap method of reducing pre-echo during transients, without using short blocks (and

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

Hi All, Since I continue to base my work on top of Jonathan's patch, and my previous Ne10 fft/ifft/mdct_forward/backward patches, I thought it would be better to just post all new patches as a patch series. Please let me know if anyone disagrees with this approach. You can see wip branch of all latest patches at https://git.linaro.org/people/viswanath.puttagunta/opus.git Branch:
