Faust conference: IFC 2018 videos are now online!

by Albert Graef

Hi everybody (and sorry for crossposting), as some of you may have noticed, IFC 2018 (the very first International Faust Conference) took place at the Johannes Gutenberg University at Mainz/Germany this week. It was a great conference IMHO, and if you couldn't attend, you can find videos of all the presentations and the Faust award on our YouTube channel now: https://www.youtube.com/channel/UCAr7dIdjRWkyZfeBU1nzOQg (If you have a YouTube account, please subscribe to the channel, then we might be able to get a nicer link in the future -- I think we need 100 subscriptions to be eligible for that.) All the videos are in a single playlist which is (mostly) in 1-1 correspondence with the program at http://www.ifc18.uni-mainz.de/#program. Click here: https://www.youtube.com/watch?v=6yvbWtD0asY&list=PLS2hQ1I9cbi4WFVhcBIuD259B… Apologies for the subpar audio quality in some spots! While most of our equipment was working really well and our stream team (Sebastian and Wingel) did a marvelous job, our wireless mikes turned out to be rather crappy -- we'll do better next time. ;-) Enjoy! :) Albert -- Dr. Albert Gr"af Computer Music Research Group, JGU Mainz, Germany Email: aggraef(a)gmail.com WWW: https://plus.google.com/+AlbertGraef

Are there benefits to running a USB 2.0 audio interface on a newer version port?

by hollundertee＠gmx.net

Hi, I've started to live stream a bit during the last year and just now added headphones to the mix. I started to wonder whether my audio interface can actually supply enough power to both a condenser mic and a pair of headphones. I figured out that newer USB standards allow for more power hungry devices, but does that in any way help with a USB 2.0 device? My interface is the same old Edirol UA-25 that I've been using for a couple of years now. It is USB 2.0 and bus powered. It needs to supply a Røde NT-1A with phantom power and drive my new AKG K702s at the same time. I noticed that I need to increase the output gain a fair bit to get a good level (roughly at 50%-60% whereas I have it at 20% with speakers). The rig I run this on I built last year, it is based on a ASUS PRIME B350-PLUS which provides USB 2.0, USB 3.0 as well as USB 3.1 ports (although I can't tell which USB 3.1, way to go on that naming scheme, my only explanation is they ran out of numbers). I don't have other gear to compare, do you think the UA-25 can handle it properly? Is it any help to plug it into a USB 3.0 or 3.1 port? Best Regards, Philipp

New soundset for Prophet-12 (Linux-edited)

by Jeanette C.

Hey hey, it's not strictly on-topic, but I did organise and name all the sounds on my Linux machine, using a self-written set of commandline tools. Alas, they're still in a sorry state. :( http://juliencoder.de/sound/Jeannys_Genius-Prophet-12-1.0.zip Four soundsets (uploadable to every internal bank(s)), HTML documentation, including browsable lists of patches by soundset, sound type, sound colour, genre and synthesis method. As pleasant a software synthesizers are and as powerful as they may be, sometimes a "custom taillored" hardware UI makes sound design and performing a more pleasurable experience. I hope that someone can/will enjoy them. Best wishes, Jeanette -------- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s And when you say those words It's the sweetest thing I've ever heard <3 (Britney Spears)

Jack, onboard souncard and headset

by Alf Haakon Pietruszka Lund

Hello list, I encountered a small but annoying problem on my Toshiba Sattelite p850 running an updated version of Ubuntu Studio 16.04 LTS: I'm currently in a location without my regular external soundcard available and wanted to do some project editing in Ardour. Running Ardour through jack outputs sound to my onboard speakers, however it would be convenient to listen through my headset while doing this. But speakers and headset turns silent as soon as I connect the headphone jack. I'd be thankful for any input that might point me in the right direction. Regards, Alf

Joining DTS audio from split files

by Bearcat M. Şándor

Hey folks, I have a set of 3 vob files that contain dts audio. There is no 'chapter' info in these files. There should be multiple break points, but the person that made them just made 3 files of reasonable length. What i'd like to do is join them and then resplit them where the breaks should be. My eventual aim is to turn them in to wavpack files. I can't find a good commandline method using ffmpeg, sox or cat to smoothly join them as vob files, w64 files or wavpack files into one. Has anyone done this successfully and can point me in the right direction? -- Bearcat M. Şándor Feline Soul Systems LLC Voice: 872.CAT.SOUL (872.228.7685) Fax: 406.235.7070
