inagy Posted July 18, 2012 Share Posted July 18, 2012 OPUS is a new codec from the Xiph guys who are behind the Vorbis and Theora projects. http://www.opus-codec.org/OPUS is a low delay royalty-free open source lossy audio codec which was initially developed for telecommunication purposes but as it turned out it's very good for archiving and streaming purposes aswell. It can be used to encode music, speech and mixed content. It's actually two codecs integrated into one: CELT (the pilot codec behind OPUS) and SILK (originally used by Skype for speech encoding). It can target bitrates from 6kbps to 510kbps and has VBR and CBR modes.Tests shows that Opus easily outperforms HE-AAC at 64kbps (http://people.xiph.o...eg/opus/ha2011/) and scales very well with bitrate. It also has a very good error correction mechanism for streaming.The codec just became an IETF standard and the latest Foobar beta now includes a decoder built in. There's an exp branch which focuses on optimizing the quality (similar to aoTuV by Vorbis).I think it would be a very cool addition to Poweramp to support this codec. It is embedded system friendly; as i know there's already an integer only decoder available in the source package.What do you think? HydrogenAudio guys are very excited about the codec http://www.hydrogena...showtopic=86580 Link to comment Share on other sites More sharing options...
australix Posted July 27, 2012 Share Posted July 27, 2012 I would also love to see Opus in Poweramp. I currently use HE-AAC, but Opus seems to perform better (and HE-AAC already performs admirably). Link to comment Share on other sites More sharing options...
Canar Posted August 1, 2012 Share Posted August 1, 2012 I would also love Opus support. Speaking as one of those "Hydrogenaudio guys", yes, this codec is very exciting. I'd like to help test, and one of the best ways to help test is to find places where Opus fails. One of the best ways for me to do that is to encode a bunch of music as Opus and then listen to it.

Undesirable Posted August 18, 2012 Share Posted August 18, 2012 +1 to OPUS support. I have encoded a number of files, and they sound great at 80 kbps. Link to comment Share on other sites More sharing options...

iGold Posted September 8, 2012 Share Posted September 8, 2012 Also vote for Opus support!Opus will be optimal music format for me on Android phone. I have audio player with 60 GB HDD and ogg music coded @ ~160kbps, but want switch to android with Poweramp as primary music player. And for the phone with 32 GB SD card which common for all phone apps small bitrate is prefered. But at small bitrate Opus is a format with the best sound quality (according to hydrogenaudio tests).So I also request to add Opus support to Poweramp.

MisakaImouto Posted September 13, 2012 Share Posted September 13, 2012 This feature is something I'd love to have as well.Opus is looking to be a pretty amazing codec and things like Firefox, FFMPEG and Rockbox all have support for it already, so if Poweramp had it I could encode my entire collection in it.

maxmp Posted September 14, 2012 Share Posted September 14, 2012 Actually, we're looking into adding it. Most probably will be in the next intermediate build.Thanks! Link to comment Share on other sites More sharing options...
Yoshi17 Posted September 15, 2012 Share Posted September 15, 2012 Thank you very much for your support.Since very early beta I'm doing test why CELT and now OPUS codec and I think it is a very promising codec since it approaches HE AAC V2 quality on some sample at 56 Kbps and the quality exceeds all other lossy codecs at 128 Kbps.I have converted all my lossless library in HE AAC V2 at 56 Kbps (fraunhofer codec) and it take less than 14 GB space on my android system. It is surprisingly small but the quality is just enough to beam sound on car speakers or bluetooth portable system (like my bose sound link), but not enough to listen with headphones.Hope to test OPUS coded files with my embedded android system and my Sennheiser HD650.

@Poweramp2 Posted October 6, 2012 Share Posted October 6, 2012 Opus would be very great. Any news on an ETA ?That's one thing we can never really give you is an ETA on updates... Due to the fact that bugs might come out of no where, or new phones might be released... Slowing down our release time. Sorry! Link to comment Share on other sites More sharing options...

skamp Posted November 1, 2012 Share Posted November 1, 2012 Great! Please make sure to add a preamp option specific to Opus though, since its replaygain implementation use a reference level of 84 dB, 5 dB lower than normal Replaygain. It would be nice to be able to match volumes between Opus and other codecs.Edit: on second thought, it might be simpler to systematically adjust Opus reference level (84 dB) to Replaygain reference level (89 dB). If users prefer the 84 dB reference level, they can always use the preamp. Link to comment Share on other sites More sharing options...
steckel Posted November 2, 2012 Share Posted November 2, 2012 Opus is successfully added to current Poweramp dev buildsGreat work. But I have not found a download link for the dev build. Can you tell me when this feature is released with an official update or give me a hint where to donwload the dev build ? Link to comment Share on other sites More sharing options...
haddy Posted November 2, 2012 Share Posted November 2, 2012 Dev builds are internal for developers only - is why they are called "dev builds"...Duh Link to comment Share on other sites More sharing options...

haddy Posted January 26, 2013 Share Posted January 26, 2013 Yeah I am awaiting Poweramp 3.0 beta too.Seems like Max is MIA these times on this forum.I want to test Poweramp 3.0 so badly. Link to comment Share on other sites More sharing options...
