Anyone got any experience of this unit. It looks very good (on paper), seems to have been in production for about 4 years, and is a very attractive price from the usual suspects. It appears to be class complient, and unlike many others doesn't have a lot of internal routing and effects. This suits me fine - no obscure windows only software controls! -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

[LAU] rtl-sdr ?

by Dave Phillips

Greetings, Does anyone here have experience with rtl-sdr, ideally on Fedora ? I'll receive my hardware tomorrow, I'd like to get up & running asap, so any tips would be much appreciated. I'm on Fedora 23, and I already know about http://rtlsdr.org/ and http://www.rtlsdr.com/. Btw, I'm interested in this stuff because of a relevant module for VCV-Rack (and because it looks like fun). Best, dp

[LAU] Small, good quality headphone DAC ?

by Niklas Reppel

Hi, recently i compared the headphone outputs of several Laptops and my audio interface. I was amazed (or shocked) how different they are, so i'd like to have something portable as a reference. I was thinking about something in the lines of FiiO, MiniDsp HA-DSP, or Apogee Groove. Should fit in the pocket, not a desktop product. Maybe somebody has some experience to share about this ? Best, Niklas -- Niklas Reppel www.parkellipsen.de

[LAU] Real-time percussion modelling 'demo'

by jonetsu

A few times in the past, and even recently, there were some comments regarding the lack of a technology that could translate relatively well the percussion gestures done by hands. That technology exists and is quite affordable. It comes from Standford University and was licensed by Yamaha. The Korg used it to make the Wavedrum. Since I connected mine today I thought of doing a quick 'demo', just 1 minute in which: - fingers are brushed - nails are brushed - fingers are tapping - nails are tapping - pressure is applied and variations thereof. The Wavedrum is connected to the usual stereo tube preamp and compressor used for acoustic guitar, but with different settings, and then a bit of reverb was added. The Wavedrum currently has a Remo drum skin. Sound On Sound calls it 'true physical modelling'. https://soundcloud.com/nominal6/wavedrum1 Cheers.

[LAU] Jack - buffers V periods

by Will Godfrey

I'm getting a little confused when comparing our (Jack) buffer sizes with those discussed on Windows, Mac and general music groups. These latter never mention periods at all, and it's always frames per buffer, so when trying to make comparisons should I take buffers as 1:1 or should I be comparing their buffers to our periods? -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

[LAU] [Almat] CALL - Workshop-in-Exposition: Thresholds of the Algorithmic - ALMAT @ BEK

by IOhannes m zmölnig

Call for Applications: Workshop-in-Exposition: Thresholds of the Algorithmic Bergen (NO), June 2018. (sorry for x-posting -- please distribute) Algorithms have been used in music and sound art even before the emergence of “computer music” in the 1950s, but today we witness an entire new wave of interest, reflected in festivals, genres, publications and research projects. It is the very notion of algorithms that is shifting. They are no longer an abstract formalisation, but emerge from artistic praxis and experimentation and become entangled in it. Almat and BEK are happy to announce a call for participation in a workshop-in-exposition taking place in Bergen, Norway, June 2018. This will be a part of BEK and Notam’s ongoing series of workshops for advanced users. It is a hybrid format that places the workshop inside an exhibition context, where the exposed works and artefacts form the basis of the workshop’s activity. Instead of “closed works”, what is exposed to the general public are objects, sounds or installations that are open to engagement and reconfiguration during the workshop. Algorithms that Matter (Almat) is an artistic research project funded by the Austrian Science Fund FWF, PEEK AR 403-GBL, and based at the Institute of Electronic Music and Acoustics (IEM) in Graz, Austria. BEK and Notam are centers for innovation and use of technology in music and the arts in Norway. Both Notam and BEK have a strong focus on education, and strive to establish new goals and provide new impulses for current music technologists and artists. - https://almat.iem.at - http://www.bek.no - http://www.notam02.no - Full text of the call: https://almat.iem.at/assets/downloads/almat-bek_call2018.pdf - Application form: https://almat.iem.at/assets/downloads/almat-bek_form2018.pdf ## Theme and Format Thresholds are locations of transitions, points where one modality becomes another, where a qualitative change occurs. In physics the point where an aggregate state changes—the phase transition—is a distinguished transitional location were the properties of the adjacent states become evident. Similarly, in this workshop-in-exposition we want to study the properties of the algorithmic by putting ourselves in threshold positions and actively shape them. More than merely separating two sides, one can spend time on a threshold, move along a ridge, performing a tightrope walk while trying not to fall to either side. Situated within the Almat artistic research project, this event aims at bringing together practitioners and researchers in the field of digital art, sound art and computational aesthetics. The hybrid format of workshop-in-exposition puts on display works of the participants pertaining to the theme, and at the same time avails them for interrogation, discussion and reconfiguration during the week long workshop. The full call embeds a list of three different ‘thresholds’ from which the applicants should point out a specific one, that they recognise as being addressed by their own artistic work. This will act both as a point for further exploration during the workshop and as a bridge towards audience perception. ## Application Please read carefully the call and fill out the form provided at https://almat.iem.at/call2018.html and send it to almat(a)iem.at along with the required accompanying documents. We aim at a balance of gender and background of the applicants. Conditions: - Duration of exhibition: from 08 June to 17 June 2018 - Start date (in situ): 04 June 2018 (preparation and set up from 04 June to 08 June 2018) - End date: 17 June 2018 - Applicants must be present during the workshop. - Workshop fee must be paid by confirmed participants (see form) **Application deadline: 16 February 2018** (e-mail reception, 24:00 CET) If you have further questions, please do not hesitate to contact us at almat(a)iem.at. iem.at | kug.ac.at | bek.no | notam02.no | fwf.ac.at

Re: [LAU] AMD graphics card

I am currently running 4.14.12 modified with the RT patches installed (the kernel provided for Fedora 27 by the CCRMA repository), and it is running quite fine with an Asus HD5450 card. That series of cards uses the older radeon driver and was previously broken for a few releases around the 4.11.x time frame, at least in the Fedora 26 kernels. I do not think Fedora modifies the graphics drivers, so I suspect that a regression with the older cards crept into the mainline at some point and was corrected in later kernels after it was noticed. I pulled the HD5450 card from a machine retired recently, I have been running a newer RX 460 card which uses the amdgpu driver (which replaced the radeon driver for AMD GPU for the latest generation devices). The newer card was prompted primarily by my kids who wanted better graphics for Minecraft, but with the working driver I do not see any noticeable difference in desktop use with a browser, playing youtube videos, etc. The HD5450 is single width vs. dual width, passive heat sink vs. fan heat sink, and lower power. I can recommend it for anything not involving 3D graphics, I used it for several years with no problems until the driver regression in the 4.11.x series of kernels, which as far as I can tell is completely corrected with the 4.14 kernel I am currently running. -- Chris Caudle
