Hi All; This is my first post to the OPUS group but I would like to find out if anyone is using OPUS over Bluetooth? If so, I have some follow-up questions on the implementation strategies that have been used. Is anyone using OPUS over A2DP? Is it possible for off-the-shelf OPUS bluetooth devices manufactured by different companies to be compatible with each other? If so, which A2DP Audio

Opus is specifically designed to survive tandeming but you need to keep the frames aligned and not mess with the gain, which your tools probably do not do.

Hello, I am really curious about something. How does the quality of Opus compare to alternative VoIP codecs like AAC-ELD V2 and EVS? I heard that the use of ACELP in EVS and AAC-ELD offers a slight improvement in low bit rate performance relative to Opus but then I also heard that the improvement is insignificant. Thanks for taking the time to read my question. -- mo -------------- next part

using iTunes i've noticed that AAC is very good at re-encoding own lossy sound. let's test Opus! neroaacenc.exe -q 0.75 -if 000.wav -of 001.m4a neroaacdec.exe -if 001.m4a -of aac001.wav wavdiff.exe 000.wav aac001.wav Comparing 000.wav - aac001.wav...

Hi all, I am interested in using the OPUS codec for real-time application on an (preferable low-profile) platform. In order to choose the optimal processor (memory size, speed,...) I have the following questions: - We have compiled OPUS on a PC with Linux OS and on a dual-core Cortex A9 with Linux Kernel. Can OPUS run on a processor with no specific OS, or are there

Looking at the Opus comparison page[1], I can't figure out whether the Opus/AAC/Vorbis/MP3 lines are meant to imply a mono or stereo encoding. Could someone please update the caption to clarify this? The single dot for G.711 is clearly mono, but for stereo music, are the codecs at the top meant to converge near 128 kbps, or 256 kbps? [1] http://opus-codec.org/comparison/

Hello everyone. I would like to use the opus codec in the following scenario: the PCM audio signal, coming from bluetooth module is captured by STM32F446 MCU and then decoded by opus codec. However, I don't know where to start to build the opuslib for ARM Cortex-M4. Could someone provide any hints or give any brief guide on this?

Well, with stored music files, with close to transparency bitrate, you don't really need Opus. Now compare it with Vorbis when streaming on a low bandwidth connection with real-time latency... 2015-10-25 2:01 GMT-02:00 Christoph Anton Mitterer <calestyo at scientia.net>: > Hey. > > I just wondered,... which is the recommended bitrate and further > settings of opusenc (like

Everything above 96kbps on that table is speculative, as the highest multi-participant listening testing done was at 96kbps. Here's the results from that test, if you're curious: http://listening-test.coresv.net/results.htm As you can see, at that rate Opus ranged from slightly perceptible to imperceptible. Also importantly, note how few of the donors were able to give significant

Hello. I would like to ask if there are any chances for a tool for splitting an opus-file at a given position, and save the parts (as opus) without re-encoding (i.e. no quality loss). And vice versa: Merge two given opus file into one (if prerequisites hold). opussplit opusFile hh:mm:ss,ss ---> opusFileSplit1 opusFileSplit2 opusmerge opusFileA opusFileB ---> opusFileAMerge For mp3 and aac

Dear expert: I would like to ask about the CPU resources need if implement the "opus codec" as the Bluetooth transmission devices?(music ) we do have DSP with SRAM..., how much-approximated memory space need for running the encode, decode algorithm? any minimum CPU power requirement ??

The developers of Opus can help the adoption of Opus greatly by writing a filter to load/save files for the commercial Adobe Audition app. The older Audition 1.x/2.x/3.x versions, before Adobe went all Creative Cloud. Just a suggestion. Even if it's a GUI filter front-end for opusenc. Adobe abandoned their legacy plugins which supported a very wide range of formats - even HE-AAC, WMA Pro,

Hey. I just wondered,... which is the recommended bitrate and further settings of opusenc (like complexity and framesize) for general music (e.g. including classical music) to achieve more or less transparency? Talking about CD level audio (16bit; 44,1 kHz; Stereo) The only source I could find regarding that was: http://wiki.hydrogenaud.io/index.php?title=Opus#Music_encoding_quality But that
