Hi, Before I comment on the graphics you posted to visualize the difference between two audio signals, I'd like to ask for your help in evaluating my JPEG encoder. I've encoded an image with JPEG and then computed the difference with the original. I then converted the difference to sound. You can listen to the image difference on this clip: https://jmvalin.ca/misc_stuff/diff.wav Can you

Just to be clear, my goal here wasn't to make fun of anyone, but to drive the point that spectrograms should *never* be used to demonstrate quality. The only case where they can sometimes be useful is for diagnostic purposes. If you hear something and you're not sure what you're hearing exactly, then sometimes a spectrogram can help you figure out what it is. That's pretty much it.

Hello, you can find pure java version of Opus codec with java spi interface at my web-site: http://dmilvdv.narod.ru/Apps/opus.html   Text in Russian, but must be understandable.

FYI, the README file section on building for Windows says to see the README.md files in the cmake or meson subdirectories, but there are no README files in either of those subdirectories. -----Original Message----- From: opus <opus-bounces at xiph.org> On Behalf Of Jean-Marc Valin Sent: Monday, March 4, 2024 12:52 PM To: opus at xiph.org Subject: Re: [opus] Opus 1.5 is out -- now with ML

Hi Timothy, Because I don't see any memory overflow, remains only any memory corruption and for sure it happens inside the library. Has anyone managed to run this library on embedded systems such as STM32, NXP IMXRT1060? By using opus_demo code (decoding part)? Pls advise, Kind Regards, Leonid Shigris RT Engineer Email: LeonidS at riscogroup.com -----Original Message----- From: opus

Many people have run opus on small embedded devices. It may be the case that your VLA support isn't providing enough stack. You may want to try using the pseudostack mode which will instead put that memory on the heap and give you better control over making sure you have enough available.

And it turns out there was a missing meson file in the original release so here's 1.5.1 with the file added: https://downloads.xiph.org/releases/opus/opus-1.5.1.tar.gz Cheers, Jean-Marc On 2024-03-04 11:26, Jean-Marc Valin wrote: > Hi everyone, > > I'm happy to announce that Opus 1.5 has just been released.

Good morning. I've ran a test against MP3 format. Code: (first convert tested audio file to 16 bit 48khz with sox.exe if needed) lame.exe -b 320 48khzfilein.wav -o fileout.mp3 lame --decode fileout.mp3 -o fileout.mp3.wav opusenc.exe --bitrate 320 48khzfilein.wav fileout.opus opusdec.exe fileout.opus fileout.opus.wav wavdiff.exe 48khzfilein.wav fileout.mp3.wav -diff fileout.mp3.delta.wav

Hi everyone, I'm happy to announce that Opus 1.5 has just been released. Opus 1.5 is the first release to make extended use of ML in the encoder and decoder. You can read all the details in our demo page at: https://opus-codec.org/demo/opus-1.5/ Major changes since 1.4 include: - Significant improvement to packet loss robustness using Deep Redundancy (DRED) - Improved packet loss

Hi guys, as MP3 and Opus have very similar objectives, I think the original poster's question was a valid one: Why does Opus have more artefacts in the lower frequency ranges than MP3 has? The spontaneous suspect that lower frequency artefacts may be more noticeably than higher frequency artefacts seems plausible, also. Is it a matter of energy (which is higher for higher frequencies)? When

Hi, I have downloaded the latest stable version *1.0.2 opus audio codec* from the following link: http://www.opus-codec.org/downloads/ *Details of OS & CPU:* OS : Microsoft Windows XP CPU : intel core 2 Duo cpu I am using Microsoft visual C++ 2010 Express to build the codec (opus.vcxproj available in the package downloaded). I am able to build it & could generate the application

Hi On the opus-codec web page here ---> http://www.opus-codec.org/development/ Underneath "Source code repository" there are options to download the gits. As well as the traditional "$ git clone git://git.opus-codec.org/opus.git" there are also Snapshots. opus-master.tar.gz opus-1.0.x-branch.tar.gz It's a great idea... To download HEAD the command can be like this...
