 +====== NowNetArts 2018 ======
 +
 +  * Place: Stony Brook, New York
 +  * Date: 2018-04-19 to 2018-04-22
 +  * Programme: https://​nownetarts.org/​conference/​
 +
 +The following sections are Otto J Wittner'​s notes from presentations and demos at the conference.
 +
 +===== Campus network overview =====
 +  * 100G ot Internet2 and 20G to "​commodity"​ Internet
 +  * 10G fibers to rooms
 +  * 100G within building (!?)
 +  * 10G out from building
 +  * Nicer-net provide backbone in NY state, peers with Internet2
 +  * Public load diagrams: https://​status.noc.stonybrook.edu
 +
 +===== The NTNU-UNINETT gays... =====
 +  * Excellent presentation.
 +
 +===== Strategies for exploiting unstable networks ======
 +  * Rebekah Wilson
 +  * Background: STEIM Amsterdam, Chicago, now New Zealand
 +  * Can't play music together on commodity Internet
 +    * Can play, but not synchronously
 +  * WebRTC applied for music experimentation
 +  * Can't play old kinds of music, but can play new
 +  * Locations are out of sync => experiences at the different locations will be different
 +  * New instruments based on classical ones (e.g. pianos) may be constructed when interconnecting them via networks
 +    * E.g. two pianos going in and out of tune
 +  * Composer need to write music which is "​allowed"​ to sound different each time it is played
 +  * The digital tools do not need to be hidden / transparent.
 +  * Adding selected "​drop-out-sounds"​ to the audo stream too make packet drops more audible.
 +  * (Technical problems during demo, but webrtc was to be used.)
 +
 +===== Through a Window: Networked music composition =====
 +  * Naithan Bosse (PhD candidate)
 +  * iPad app for processing / management
 +  * A lot of tools applied in composition,​ e.g. ping and traceroute output mapped to produce chords and sounds
 +  * Stopwatch applied as conductor supplement
 +  * Synch opportunities added frequently in music score
 +  * One anchor musician (master clock)
 +  * Composition performed in 3 site setup, theater, "​wet"​ studio and "​dry"​ studio
 +    * Audience in all locations, surrounded by speakers
 +    * Noe video between sites applied, intentionally
 +    * Immersive experiences created (via surround effects)
 +
 +===== SpinStack =====
 +  * Michael Richison
 +  * A composition installation based on two turntables
 +    * Infraread sensors detect distance to spining stack of slices of shaped cardboard
 +    * A percussion machine is controlled by the turntable speed and the sensors
 +    * Projectors project graphics onto the slices
 +     
 +===== Evaluation of Network Music Technology =====
 +  * Chris Chafe, Trever Henthorn, Sarah Weaver
 +  * Jacktrip origin
 +    * A sw packages to connect three sights running the Jack sound server sw, hence Jack-triple or Jacktrip
 +  * Measurements showing jitter issues with different network connections
 +    * Wifi show up as rather messy => wires still recommended to keep losses low
 +  * What to replace lost packets with?
 +    * Jacktrip applies zeroes of a copy of last packet (waveform mode)
 +    * Should there be many small glitches or few larger ones...?
 +    * Clock drift between peers a problem not at all solved
 +  * ...
 +
 +===== Spirits of Water =====
 +  * Yoon Jeong Heo, Hilary Finchum-Sung
 +  * Korean Music across the Globe
 +  * Traditional Korean instruments and music
 +  * Historical info, north v.s. south ...
 + 
 +
 +===== Jamming in the 3rd room, Virtual real-time recording =====
 +  * Paul Ferguson et al
 +  * Intro to Lola
 +  * Lola a tool to enable real-time recording for studios
 +    * Instead of todays practice moving audio files between remote musician and studio
 +  * "3rd room" meaning the virtual room created by Lola rigg and the network
 +    * What are the musical rules to play in such rooms?
 +  * Gareth Dylan Smith (drummer) experienced a feeling of improved audio quality when video resolution was increased during a Lola session.
 +  * Quality of Lola audio stream is good enough for playing together, but not for recording
 +  * Funky demo with drums (local) and sax (remote from Edinburgh)
 +    * Almost in sync, no doubt two musicians playing together
 +    * But mix of live audio from drums and PA only audi from sax made experience for audience lesser
 +  * Success with synced recordings one both peers combined with Lola as "​cue"​-stream for musicians
 +    * When recordings stop they are pushed and shared in cloud storage
 +
 +
 +===== Music without borders and MIRCO =====
 +  * Maria Minaricova, Paolo Girol, Kristina Lillemets
 +  * Geant expansion eastwards in Europe
 +  * Services: Eduroam, EduGain, Prefsonar, Lola as a service (!)
 +  * Lola as a service includes equipment and support in getting nodes operative
 +  * Lola sessions to GARR (Claudio) and Estonia
 +  * Samples of misc master classes for classical music
 +  *
 +
 +
 +===== Survey paper on net music tools for music production ? =====
 +  * Rebekah Wilson, source-elements.com

 +  * Chris Chafe
 +  * Online 6 weeks course teaching Jacktrip, offered by Standford (?)
 +    * Kandenze MOC
 +  * Internet acoustics (for network reverbe)
 +    * Even though audio streamed of internet paths are impaired with added delay, the audio itself is unchanged.
 +    * Musicians reactions to Internet delay may change the audio
 +    * Internet applied as FDL (feedback delay loop)
 +      * (Some delay added locally to avoid all audio streams to have identical delay
 +    * Resulting reverberation resembles some kind of "​Internet room".
 +    * Feature is added to Jacktrip in upcoming version
 +  * Repetition of results from delay experiments with clapping
 +    * Model for human clapper was poor in 2012. Still being imporved
 +  * New experiments based on web page where user attempts to tap in sync with adaptive tapping algorithm
 +    * user taps along with metronome, sine wave driven metronome, adaptive alg and delayed adaptive alg.
 +    * "When do you sense your partner is listning?"​
 +
 +===== Staging Networked Music Performance =====
 +  * Ian Biscoe
 +  * Historical perspective on presentation of networked performances
 +  * Run through of Ian's projects including
 +    * Danish royal academy of music in 2017 performance
 +  * New visual project has premier April 25th in Miami
 +
 +===== Reflections on collaborative telematic music research =====
 +  * Zurich University of Arts and Onsite
 +  * Performance
 +    * Some local bass fed to local speakers to merge remote and local musicians better
 +    * Tables put up right applied as projection screen for single-person projection
 +  * Telematic rooms open doors to new musical performances
 +    * Care should be taken to not only "drive our new space shuttle down the highway the usual route"​.
 +  * System applied
 +    * Jacktrip for audio and Ultragrid for video
 +    * "TPF server"​ developed to manage it all
 +      * Software packages required are organized by TPF package
 +      * Written in Pure Data and Python
 +      * Available on Github
 +      * Seems to reinvent STUN and TURN functionality
 +  * Staging the telematic space: Videos in telematic space
 +    * Telematc space not only a technical space, but also a mental space...
 +    * Proportions
 +      * Imitate the life size of people, e.g. table based projection surface
 +      * Tech-choreography required
 +    * Apply a T-screen to offer monitor screen for on stage musicians and screen for audience
 +      * Additional projector and screen => complexity increase
 +    * Transparent screen
 +      * Musicians behind screen may still see projection
 +      * Impression of remote person being present is imporved
 +    * Embodyment
 +       * Monitor towers showing each remote musician, included audio monitors
 +       * Audience could walk around, between the musicians ​
 +    * Moving in space
 +       * A movable speaker represented remote person
 +       * Movable live size projection screen, applied for dancers
 +         ​* ​ Creates opportunities for explore the "​telematic space"
 +  * Transcending place but not time zone
 +     * Who has "prime time" when collaboration takes place across time zones ?
 +       * Time of day influences how a concert is experienced by the audience
 + 
 +
 +===== Panel: Carbon footprint and NetArts conferences/​work =====
 +  * Q1: To what extent is remote presentations given in music conferences?​
 +    * Still unusual. Only occasional. A fear for lost informal social interaction.
 +    * Important topic. Network-musicians do meet "​informally"​ and "​deeply"​ through online collaborations.
 +      * Upcoming online event illustrating CO2 evolution on earth. icewalkeath.org ?
 +  * Q2: What does it take to offer ti?
 +    * Given the venue is in an academic institution,​ infrastructure and support tends to be available
 +    * Hotel venues may refuse you/charge extra if Internet is to be applied for presentations
 +    * Zoom seems to be a game changer with respect to multi-participant on-line meetings
 +    * Avoiding a centralized system (relying on a hub/​management node) would be preferable
 +      * Ideally there should just be presistant rooms where people join and leave over time (WebRTC?)
 +  * Q3: What is required to make a better user experience for VC?
 +    * The community has talked to Zoom. No enhanced audio mode on the road map yet...
 +
 +===== Distributed performance at NY univ. Steinhardt =====
 +   * Tom Beyer
 +   * Manages a generous infrastructure including 3 theaters, 9 classrooms, 4 recording studios
 +   * Teaches courses including workshop in networked music collaboration in summer term
 +   * Historical summary.
 +     * Collaboration with UiT in 2012-2015
 +   * Upcoming concert
 +     * http://​wp.nyu.edu/​immersiveaudiogroup/​concert-links
 +     * 29th April 15:00 EST
 +     * Dancer with avatar on stage
 +     * 360 video and ambizonic audio
 +   * Apply clapping exercise with increasing tempo to measure which tempo works with respect to latency
 +     * Given tempo and "​on-second-beat"​ situations, students are asked to come up with playing strategies
 +
 +===== Double Brain =====
 +  * Brain waves applied as input to audio generators (brain wave soundification)
 +  * Presentation summarizing work done while sounds of speakers brain activity is mixed into the audio stream
 +  * Tool applied to share (peer-to-peer?​) brain wave data flows
 +    * Two prosessed streams (meditation and one other...) as well as raw data
 +    * Raw data show significant pulses on eye blinks
 +  * Concert project where audience were asked to ware EEG equipment
 +    * Questions were posted on projection screen, and EEG data from the audience drove audio generators when they answered questions in their brains ​
 + 
 +===== Virtual Cistern Concert =====
 +  * Improvisational concert i virtual version of a 100 year old water cistern in Zurich.
 +  * Very long reverberation time
 +  * Cistern concert also made in NY shopping mall successfully using the mall's built in info-speaker system
 +
 +===== Toporhythm =====
 +  * Ethan Cayko
 +  * Delays in the order of 50-150 ms are to short to attempt applying shifted rhythmic patterns, e.g. a shift by an 8th at 122 bpm requires a delay of 250ms
 +  * Earlier work on "​staying in synch"
 +    * The "​staying in synch"​-time window is interpreted rather differently by e.g. percussionist and string players
 +  * Tool/patch in Max developed which adds the "​missing"​ delay to enable wanted/​usable off beat rhythms.
 +    * Needs calibrations. Applying a metronome is recommended.
 +  * Three node rhythmic piece written with different delay between the three percussionists
 +    * Sometimes human error cause up to 20ms miss hits
 +    * Occasionally perfect synch happens => outputs a "​strange"​ crisp sound
 +  * How to create rhythms for more than 2 nodes...?
 +    * A Toporhythm visualizer made available to help compose
 +    * Algorithm generates notes for additional nodes when rhythm for "​master"​ node is prepared
