Fwd: Custom mode
---------- Forwarded message --------- From: Peter Svensson <petersvenss85 at gmail.com> Date: tis 19 feb. 2019 kl 20:43 Subject: Re: [opus] Custom mode To: Emily Bowman Hi Emily ! Thank you for responding. I think my problem is not (yet) with OPUS itself. Encoding at complexity 0 takes 1.6ms ( 4.342ms at complexity 10 !) and decoding takes 1.9ms. 3.5ms, out of my 4.096ms budget, is

24 bits samples
Hi It pretty works for 16 bits samples but not for 24 bits samples. In fact, I am going to implement opus on ADSP-21489 (DSP processor from Analog Devices), I compiled "celt directory" from opus 1.1 and used "opus_custom_demo.c". It hasn't any problem with 16 bits samples but when I use 24 bits samples , there is no output audio. opus_decoder will still generate 16 bits

OPUS_SET_MAX_BANDWIDTH does not have expected results
Hi All. I am seeing the following unexpected behavior with OPUS_SET_MAX_BANDWIDTH. I expect that setting this to OPUS_BANDWIDTH_NARROWBAND would give similar results to passing an 8Khz sample rate stream, but OPUS_SET_MAX_BANDWIDTH has almost no effect with any settings. My test data has 4Khz bandwidth. I am testing the opus encoder (latest versions) with the following opus_encoder_ctl

Opus multi-stream/surround: Audio corruption on decoded content
Hello Everyone, I am using the opus 1.1 multistream APIs to encode a 5.1 surround stream on the server, stream it to client, decode it and capture the pcm data. I noticed that there was severe corruption/attenuation on one of the channels(specifically Back/Rear Right). This would appear to be the last channel in the stream. I am attaching an image of the PCM dumps from the original and the one

Global stack on Cortex-M4
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

[Windows]Issue with opus 1.2 : lnk2001
Hi, I got libopus 1.2 from the download page. I compiled it using visual studio 2015 with your configuration (Release). I integrated opus.lib and the new include files in my own solution, but when I compile, I found 28 link errors (lnk 2001): - silk_Encode - ec_enc_init - celt_inner_prod_sse - opus_select_arch - silk_InitEncoder - ec_enc_shrink - silk_log2lin - ec_enc_bit_logp -

Ask for suggestions about optimizing opus on STM32F407
Hello Thomas and Amit, Thanks for your notice and the detailed decode performance report. I describe the details of my encode/decode test on STM32F407ZG. A. opus version: latest 1.2.1 (TI: opus 1.1.2) B. KEIL 5.23 (TI: ARM compiler tool chain 5.2.7) C. setup the encoder as the below (fs is the sampling frequency) enc = opus_encoder_create(fs, chans, OPUS_APPLICATION_AUDIO, &opus_err);

Opus complexity and VOIP for mobile devices
Hi,? Anyone could provide more information on the level of complexity (OPUS_SET_COMPLEXITY(x) , x between 0 and 10 ?) which is recommended for generic Android devices ? How about the iPhone devices ??Is there a way to choose this complexity level according to the device model ? Any hints ? We've seen they set 5 in webrtc :http://code.google.com/p/webrtc/issues/detail?id=3093Freeswitch is

help to add assembly files
Hi , I am trying to optimize OPUS codec to TI compiler C64XX in CCS. I have created the make file and compiled the code in optlevel = 3. The MIPS are pretty high(99 MIPS for 8Khz stereo) for LFE channels and the most MIPS intensive function is the silk_noise_shape_quantizer_del_dec() function. 1. I am trying to convert this entire function to assembly. I have tried to incoporate .asm file but I

[EXTERNAL] Re: Developing OPUS on TI CC3220
Thanks Jean-Marc, I was able to get both encode and decode working the CC3220 device! But for bi-directional communication, I need decode and encode to occur in less time than the frame size I’m sending (20 ms). Currently decode takes 16~22 ms and encode is ~13 ms. What is the best way to try to reduce this time? Also, unsure why encode is taking less time than decode... I've also

[EXTERNAL] Re: Developing OPUS on TI CC3220
Jean-Marc, Thanks for the response and the helpful info. I am trying to get the library to build without using the pseudostack define, and use either VAR_ARRAYS or ALLOC, but it seems the global stack is not defined. Where do can I define this in my example? VR -----Original Message----- From: Jean-Marc Valin [mailto:jmvalin at jmvalin.ca] Sent: Tuesday, February 20, 2018 5:40 PM To:

Bug in ARM fixed-point ASM?
Hi, folks, I've been hunting down some strange bugs in audio I've been doing. While hunting my bugs down, I tripped across what appears to be an Opus bug, but it's not clear where it's coming from. Note that the optimization choices differ between the two in the config.log below. How can I force them to be the same? Presumably I need to force the android version toward the

ASM runtime detection and optimizations
I wrote a proof of concept regarding the cpu capabilities runtime detection and choice of optimized function. I follow design which had been discussed on IRC. Also, i notice a little drawback: we must propagate the arch index through functions which don't have codec state as argument. However, if it's look good, i will continue to implement it.
