similar to: CELT CFFT size configuration

Dear all I'm working on the implementation of the MDCT for the processor ARM-Cortex-M4 I'm trying to replicate the behavior of the MDCT for several overlapped values however I realized that current implementation of the MDCT is very close to the theory only in case in which we have and overlap exactly equal to N/2 where N is the size of the input vector as is shown in the examples for

Dear all. According with my question. CELT CFFT size configuration I'm not completely sure about how the kiss_fft works for sizes which are not power of two, as occur in the case of celt which calculate the mdct using a fft sizes of 480, 240, 120, and 60, I guess that internally the input data is padded with zeros in order to compute efficiently the mdct using the Cooley and Tukey

Dear all, Currently I'm working in and optimization of opus for an arm-architecture *"armv7e-m"* I've involved in the general opus documentation as well in the architecture, however opus Is so big and difficult to discover specific optimization points, I want to know if you could give me a general view about of the principal points that I have to consider in order to optimize

Dear all In the paper section describes how CELT and SILK had implemented a look/up head delay of (2.5ms), (5ms) respectively , could you explain me> 1) those values are fixed. 1) how you guarantee those values independent of the architecture's performance.

Hi Diego, Really, the only way to know what to optimize is to run a profiler. Optimizing without profiling is a waste of time and is often harmful.

Dear all: I want to formulate couple of questions about SILK codec: 1. I've seen the documentation to the SILK codec that is part of the OPUS exactly the paper with title "The opus codec voice coding with opus, and the "RFC 6716 specification of opus" . Well, I detected that in both is defined a High-Pass filter as part of SILK; however in the paper you put the following

Hi all: I'm successfully run OPUS in cortexM4 arm architectures using a cross compiler gcc-arm-none-eabi . I recommend to uses the following precompile flags before to compile you code: arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -mfloat-abi=hard -mfpu=fpv4-sp-dl16 -std=c99 -fasm -DARM_MATH_CM4 -DOPUS_ARM_INLINE_ASM -DOPUS_ARM_ASM .... and in your configuration file of OPUS you could use the

Hello, I have a small Puppet 2.7 module to configure Sonatype Nexus Professional. The module takes, among other things, a baseurl in the form of "http://example.com/path" and I''d like it to extract the "/path" from that variable into a separate variable IF an optional "path" variable haven''t been supplied. Here is an extract: class

Hola, El próximo 26-septiembre comenzamos la nueva temporada de reuniones del "Grupo de Usuarios de R de Madrid". Esta temporada trae algunas novedades, una de ellas es que intercambiaremos el lugar de las reuniones entre la Facultad de Ciencias de la UNED y ahora el bar S10 en el que esperamos mantener unas reuniones más próximas y si cabe informales. Por ahora tenemos un par de

Hola, Una breve nota para recordaros que hoy tendremos la reunión del "Grupo de Usuarios de R de Madrid". La reunión de hoy será un Taller práctico "Introducción a la elaboración de Mapas con R". ¡Os esperamos!

Deberías instalar también, como poco, ggmap. RStudio no suele venir nunca mal. No sé si hay wifi en el bar para instalar las últimas dependencias... Un saludo, Carlos J.

Hola a todos: efectivamente, esas son las librerias que convine tener instaladas. Llevaré los datos que utilizaremos en un pendrive (por si acaso falla la wifi) y también el *.md del código para poder seguir la demo sin escribir todo el código! Para esto, yo creo que lo mejor es abrir el *.md con R Studio. Esta tarde nos vemos! -- Beatriz Martínez @_bmartinez_

Hola Beatriz, Si me pasas el *.md lo subo a un Dropbox y si no es muy grande lo subo a R-Hispano (linkándolo a la agenda).... Saludos, Carlos. El 29 de octubre de 2013 15:56, Gregorio R.

Hi, I am working on DSP module of Ne10. I see there are fixed-point and floating-point FFT inside Opus. Is fixed-point FFT only a fall back for CPU without VFP? On ARMv7-A and ARMv8-A, benchmark result shows that fixed-point (int32) and floating-point (float32) FFT have similar performance. I guess fixed-point version is not often used on these platforms. Is it worth the effort to NEON-optimize

Hi LLVM developers, As PR35281 mentioned: $ llvm-objcopy -O binary llvm-cortex-m7.elf llvm-cortex-m7.bin llvm-objcopy: 'llvm-cortex-m7.elf': The file was not recognized as a valid object file. if (ELFObjectFile<ELF64LE> *o = dyn_cast<ELFObjectFile<ELF64LE>>(&Binary)) https://github.com/llvm-mirror/llvm/blob/master/tools/llvm-objcopy/llvm-objcopy.cpp#L200

Analog Devices sponsored a fixed point version for AEC which was posted early this year, but it seems from the source code that the fft routines are still in floating point. Is the port still not complete or am I missing something? Has anyone out there ported speex AEC on RISC architecture? Please let me know.
